What is a horn antenna?
A horn antenna is an antenna that consists of a flaring metal waveguide shaped like a horn to direct radio waves in a beam. Horn antennas are used as antennas at UHF and microwave frequencies that are above 300 MHz.
Horn antenna are typically fed by a section of a waveguide, the waveguide itself is often fed with a short dipole.
An insects horn is called an antenna.
Horn Antenna is best exited by waveguide
The opening angle of a pyramidal horn antenna is to match the impedance of the horn antenna to that of free space. With this enlargement of the dimension, the velocity of the wave travelling will decrease. This will increase the guide wavelength, which in turn increases the impedance of the horn. This gives an impedance value closer to that of free space there by giving better power transfer.
Why might a parabolic reflector horn type microwave antenna be preferable to a parabolic dish type microwave antenna?
The reflector horn type antenna has greater "side lobe" rejection, directionality and sensitivity (efficiency) than a dish type.
microwave. it couples the waveguide to open space.
waveguide is a metal pipe that contains and guides microwaves from place to place in a microwave system (e.g. oscillators, amplifiers, mixers, modulators, filters, antennas) horn antenna has a waveguide connected at its focus, in transmit mode the waveguide feeds the horn which then emits a microwave beam, in receive mode the horn collects a microwave beam and concentrates it int the waveguide
Horn antennas are extensively used at microwave frequencies when the power gain needed is moderate. For high power gains other antennas like lines or parabolic reflectors etc are preferred rather than horn antennas.
Answer GAND MARAO pyramidal horn are antennas in which the walls of the rectangular wave guide are flarred in both e-plane & h-plane directions. applications:- --> when there is a high gain requirement. --> when there is high directionality requirement.
Recently replaced the antenna motor in a 1998 Nissan maxima but now the antenna motor won't even turn on keyless entry will not work and in-dash clock has gone out any ideas what happened-how to fix?
Did You check the fuse 7.5A, does the horn work?
In GSM mainly using Panel type antennas but in the case of Microwave Antenna using Horn antennas. Microwave anteenas propogate signal straghtly. So line of sight (LOS) is main issue in the case of Microwave antenna, it means that both antennas must be allign in face to face. Microwave antennas are using for link between BTS but GSM antennas are directly link with customers. Antenna Gain also very much difference both cases. JPS o,[.[;.;[.]/]/ pppppppppppppppp
It 'collects' the radio waves, and they reflect off the dish to a 'focal point' - At the focal point is a 'horn' containing a tiny antenna. This is connected by cable to the receiver.
The underlying electromagnetic radiation mechanism is illustrated by evaluating the scattered radiated field and its effects on the aperture efficiency by considering the theoretical limits of a radiating conical horn with infinite length
Hertz Antenna is lambda by 2 antenna & marconi antenna is lambda by 4 antenna...
An active antenna has a amplifier built in, a standard antenna does not. AKA powered antenna.
Transmitter => Antenna =========> Antenna => Receiver Receiver <=== Antenna <========= Antenna <= Transmitter

Begin by removing the antenna cable from the bottom of your 2003 Pontiac antenna. Remove the antenna retaining nuts. Reverse the process to install your new antenna.
A folded antenna is a dipole type.
end-fire antenna = surface-wave antenna
antenna is antenna. It's the same language.
The 2000 Elantra's are equipped with a fixed antenna * Use a wrench on hex portion of the antenna mast to remove the exterior antenna * Remove the antenna base is acced by removing the interior trim panel * Disconnect the antenna lead from the base of the antenna and remove the mounting bolt
Remove the nut, spacer and bushing that holds down the antenna on the outside car body. Then turn the radio ON. As the antenna extends out, carefully pull out the antenna mast. There will be a plastic portion with teeth at the end. Remember the direction of teeth. When you install the new antenna, the teeth will go in that direction. Insert the new antenna into the antenna housing. Make sure the antenna teeth engages… Read More
The antenna mast screws into the antenna mount on the fender. Unscrew the old one and crew in the new one. If you need to replace the entire antenna mount, you will need a new antenna mount assembly with antenna cable.
You can replace your 2003 Toyota Echo antenna. Remove the antenna retaining nut. Remove the cable from the bottom of the antenna. Reverse the process to install the new antenna.
Begin by removing the wiring harness from your Volvo antenna. Remove the antenna retaining nuts. The antenna will come off. Reverse the process to install your new antenna.
An omnidirectional antenna can be practically implemented but an isotropic antenna cannot be implemented practically. An isotropic antenna resembles an ideal antenna with ideal values for all parameters.
No, spiders do not have antenna.

Rephrase the question, What antenna?
Remove the plastic cover from inside the wheel well to expose the antenna. Remove mounting bolt. To replace antenna purchase an antenna with an adapter. Cut old antenna wire at base and connect new antenna using the adapter.
You can replace an XM radio antenna with a CB antenna, a ham 40-meter mobile antenna, a cellphone antenna, a GPS antenna, a TV antenna, a wire coat hanger, a 6 GHz microwave antenna, or a chain of paperclips. However, since none of them is optimized to operate at the frequencies of XM radio, like the XM antenna is, none of the others will work as well. Most of them will likely be so inefficient… Read More
The answer depends on how much of the antenna system you want or need to replace. The motorized antenna system on a 1986 Honda Accord consists primarily of 3 components. The antenna assembly, the antenna motor (which raises and lowers the antenna) and the up/down switch. There is also a 10 amp antenna motor fuse in the fuse block which is located under the dash, just below and to the left of the steering wheel… Read More
Manual antenna on Elantra. Unscrew the screw on top of the antenna pull out the insert antenna and replace with new one. Simple as can be.
You would need to get a tool to remove the notched chrome piece that holds the antenna mast, or carefully use pliers to unscrew it out. After you remove that, the antenna itself is held by a 10mm bolt. to get to it you'll need to open up the trunk lining near the antenna location and remove that bolt. Then, pull the antenna far enough to disconnect the antenna wire and power. Assuming the antenna… Read More

I think Printed Antenna ( array microstrip antenna)
A digital antenna offers a clearer sound and signal than a regular antenna. There is no interference or static. However, while an analog antenna can get the signal through a hill, the digital antenna must be able to see the broadcast tower. ************************************************************** There is no difference. An antenna is designed for a particular frequency or band of frequencies. The mode of modulation is totally irrelevant.
remove the nut at the base of the antenna. Slide off the grommet. The antenna will drop os hold on the the antenna as you remove the nut and grommet. Once this is removed. You will see how to remove the antenna unit.

The stock roof-mounted antenna on the 2005 Toyota Matrix will unscrew from the antenna base that is attached to the roof. If your original antenna has been stolen, you should be able to obtain a replacement antenna and just screw it on the the antenna base that is still attached to the roof of your Matrix.
There is an antenna, but it's inside the case. (Incidentally, this is the root of the uproar about the iPhone 4's antenna issues. The antenna was on the outside of the phone, causing people to muffle its antenna-ness when holding it tightly.)
The antenna is located in the rear window defroster. There is no true exterior antenna.
Antenna is singular - a car has a radio antenna. Antennae is plural - insects have two antennae.
it will depend on what the antenna is shaped like and certain other aspects of the antenna
