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 microstrip patch array antenna?
microstip patch array antenna is basically ,thecollection of antenna that give the double directive gain
How do you test a microstrip antenna?
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.
How do you measure Characteristic impedance of microstrip line?
The characteristic impedance of a microstrip line can be measured using a network analyzer or by employing the time domain reflectometry (TDR) method. To use a network analyzer, you can connect it to the microstrip line and measure the reflection coefficient (S11), which can be used to calculate impedance. For TDR, a pulsed signal is sent down the microstrip, and the reflections are analyzed to determine the impedance based on the time delay and amplitude of the reflected signal. Additionally, impedance can be calculated using the dimensions of the microstrip line (width, substrate height, and dielectric constant) with appropriate formulas or simulation tools.
Why dipole antenna not used for high frequency?
Depends on what you mean by high frequency. The rabbit ears antenna used in broadcast TV is a dipole and is used for VHF.
Why yagi uda antenna is used?
Some advantages of the Yagi- Uda Antenna include that this is a widely used design and low cost. The construction also is simple. Some disadvantages are that the receiver of the Yagi-Uda Antenna may have problem receiving signal.
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 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?
How does a smart antenna work?
A smart antenna is used to identify signal signature and to track an antenna beam on the target. Some are for beamforming which is used to create the radiation pattern of the antenna.
What is a car antenna booster used for?
A car antenna booster is used to 'boost' the radio waves of the car's antenna. This is usually used to improve radio quality and reduce static that might be heard.
Where helical antenna is used?
it is used in space
Can magnet be used as an antenna?
Yes, a magnet can be used as part of an antenna system, commonly known as a magnetic loop antenna. The magnet helps to concentrate and focus the radio frequency energy, improving the antenna's efficiency and performance. It is a popular choice for portable and low-profile antenna setups.
What is the dominant mode of propagation in microstrip line in low frequency approximation?
