A micro-strip antenna works on the principle of resonant cavity (short circuit walls on top and bottom, open circuit walls on the sides).
A resonant cavity stores energy unlike transmission lines or wave guide which transmits electromagnetic energy from one part to another. A R.C is equivalent to LC device at low frequencies.

What is microstrip patch array antenna?
microstip patch array antenna is basically ,thecollection of antenna that give the double directive gain
Where is Microstrip antenna used?
Micro strip antenna has following advantages : 1) Low profile : conformal (most important) 2) Easy to fabricate 3) Can be used in array 4) Easy to feed the most important use of micro strip is its conformity as it can be conformed to the air crafts, missiles, satellite. A stealth aircraft has about 50-70 micro-strip antennas. the most popular of conformal microstrip antennas are Cylindrical, conical as the are mounted on various parts of aircrafts, missiles etc. they have many use on armament department.
What is a reconfigurable antenna?
an antenna that is able to be formed, or bent
Can you replace an XM radio antenna with any other antenna like a 3ft hard cb antenna?
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 at the satellite radio frequencies that when you use one of those, you hear nothing at all on your radio.
Is end fire array antenna non resonant antenna?
yes
What kind of antenna is used in base transceiver station?

How does an microstrip patch antenna radiates?
The source of radiation for rectangular microstrip radiator is the electric field that is excited between the edges of microstrip element and the ground plane.The fields are excited 180 degree out of phase between opposite edges.Each edge therefore radiates an omnidirectional pattern into half space above the ground plane.The opposing edges are excited out of phase but their radiation adds in phase normal to the element. For more details see Antenna Engineering handbook by Johnson and Jasik. Thanks.

How do you install a universal antenna?
Remove the old antenna. Attach the universal antenna to the radio and replace the radio after finishing the task. Install the new antenna. Test to ensure the wiring works.
How do you test a pl-259 connector leading to a ham antenna?
the best way is to first ohm it with the antenna disconnected test from center to shield for "open" it should be open then test from center to center for "short" it should be shorted replace the antenna and test the VSWR on your antenna
How do you practically realize the design of a double-stub impedance match using microstrip?
microstrip line is unbalanced line so it works in same way as other unbalanced line. so in double stub, the microstrip line forms the reactance wanted to match. Hey what happened to methods involving the schmidt chart?
Why test antenna in receiving mode?
If you run the antenna under test in the receiving mode, then while it is rotated, you'll monitor signals received by the antenna under test. If you run the antenna under test in the transmit mode, then while you rotate it, you'll monitor signals received by a different antenna on the test range. Either way, the varying signal must be monitored at the receiving end of the link. It's a lot more convenient, and a simpler configuration, to have the signal monitor and the rotation/excitation controls for the antenna under test in the same place, in order to react appropriately to any funny things noted during the test run.
Definition of quiet zone of antenna measurement?
A quiet zone in antenna measurement refers to an area surrounding the antenna test zone where electromagnetic interference is minimized to ensure accurate testing. It is essential for obtaining precise measurements of the antenna's radiation pattern and performance. The quiet zone is achieved by reducing reflections, scattering, and diffraction from surrounding objects and walls through proper test setup and shielding.
What is the dominant mode of propagation in microstrip line in low frequency approximation?
quasi-TEM
How do you replace a ferrite antenna with a whip?
To replace a ferrite antenna with a whip antenna, first, disconnect the ferrite antenna from the device, ensuring the power is off to avoid damage. Then, connect the whip antenna to the same point where the ferrite antenna was attached, ensuring proper orientation and secure connections. Finally, test the device to ensure that the new whip antenna is functioning correctly and providing the desired signal reception. Adjust the positioning of the whip antenna as necessary for optimal performance.
