Abstract: A simple ring slot antenna with a in built filter to reduce the higher order modes is proposed in this model. The proposed antenna is having circular polarization at the operating frequency of 8.6GHz. In general antenna will be having higher order modes of operation and to nullify it we will be having filters in the transceiver circuits but it will increase the mutual interference levels in the system and also the complexity of the system which will lead to reduction of the life span of the device and also effect the efficiency. So to make the system simple a antenna with inbuilt filter is proposed which will not receive the signals from the higher order modes and there will be no necessity for the additional filter circuits.
Keywords: Strip Feed, Filter, Higher Order Modes.
Scope of the Article: Micro Strip Antenna
