DESIGN OF DUAL FEED MICROSTRIP PATCH ANTENNA FOR INTELLIGENT TRANSPORTATION SYSTEM (ITS)

In this paper, a switchable dual-feed multiband patch antenna is designed. Twopin diodes are used in this antenna for switching purposes, and it is feed with two microstrip lines operating in 3 to 20 GHz frequency. The antenna designed here is used for many applications like ITS, satellite communication, WLAN, weather radars etc. We get different frequency bands by changing the induced current, which is done by switching the PIN diodes. The percentage bandwidth of the proposed antenna is up to 38 %.
