In this thesis, the radiation principle and the structure of slot antenna are studied and the impacts on its performance of every structure parameter in a slot antenna design are analyzed. On this foundation, a design plan of planar slot array antennas is proposed. The design has some structural feature as follows:(1) with different dielectric layers and microstrip line structure to guide the electromagnetic wave effectively;(2) the feeding network formed of microstrip line can match with the radiating slots expediently;(3) in order to increase the bandwidth of the antenna, the wider slot and branched feeding microstrip line are adopted to form a double resonance.
