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.
microstip patch array antenna is basically ,thecollection of antenna that give the double directive gain
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.
Depends on what you mean by high frequency. The rabbit ears antenna used in broadcast TV is a dipole and is used for VHF.
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.

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.
microstrip circuits can radiate
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?
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.
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.
antenna can be used in both transmission and reception
it is used in space
quasi-TEM
Sure. When used as an antenna, a magnet should exhibit the same properties as an identical unmagnetized piece of metal.
