Abstract :
A dual-loop printed antenna fed by coplanar strip-line (CPS) with high gain is proposed. This antenna not only has the high gain of 10.13 dB, but also has the low cross polarization level less than -30 dB, which can be used in a low power density application. Furthermore, the broad beam width with more than 62 degrees HPBW in the E plane is able to avoid the precise main beam alignment. For measuring, a balun from the CPS to a microstrip line is designed. The simulated results show that this balun has little effect on the antenna.
