Abstract
This chapiter starts with a general definition of the antennas. The next parts will talk about a microstrip antenna from the side of the double band in order to get an antenna that can do both reception and emission as well as developing the azimuth and angular resolution. This chapter has also introduced an antenna that separates the feeding part from the rayonnant one in an effective way that can enable us to develop the abilities of the radar antenna. Besides, it would also cope with the mechanic relation of the antenna. Another work has been presented to make electronic scanning more effective and faster. This would allow us to get rid of mechanic circulation by using butler matrix. Developing the antenna from the angular resolution has also been presented through widening the bandwidth by DGS technique and widening the reach via using the antenna array. Among the biggest problems are the surface waves and mutual coupling that present significant challenges to the designer because of their graduation of the antenna performance especially in the radar system.
