A Compact W-Band Planar Quasi-Yagi Antenna on GaAs Substrate for Active Phased Array Antenna
In this paper,a design of compact W-band planar Quasi-Yagi antenna is presented. The proposed antenna is fed by 50 Ohm coplanar waveguide with a broad-band balun in order to convert from unbalanced grounded-coplanar waveguide (G-CPW) mode into balanced coplanar strip line (CPS) mode. This antenna is realized on a high dielectric constant substrate,GaAs -relative dielectric permittivity of 12.9,thats compatible with active devices and circuits. Using the truncated ground plane as a reflector,the proposed antenna has a broad relative bandwidth of 18.07% with its return loss better than-10 dB,front to back ratio is 15.6 dB and 6.08 dBi of gain at 94GHz. This antenna can be widely applied in wireless communication systems,active phased array antenna or millimeter-wave imaging systems.
