Abstract:

 A dualloop printed antenna fed by coplanar stripline (CPS) with high gain is proposed. This antenna has a high gain of 10.8 dB, capable of receiving more power at certain power density. It has a low cross polarization level that is less than -38 dB, and a broad beam width of more than 70° halfpower beamwidth (HPBW) which does not require strict alignment of the main beam. This antenna can be used in communication systems. Balun from the CPS to a microstrip line is designed. The measured results are in agreement with simulations. 

Key words: high gain; cross polarization level (CPS); wide broad beam; coplanar stripline (CPS); Balun
