2.45 GHz Field Adjustable Gain Antenna

HFSS was used to design an antenna with an adjustable gain. The basic antenna is a circularly polarized microstrip patch antenna. A medium gain director and high gain director which screw-into the basic antenna were designed and fabricated

The Realized Antenna Design is Shown on the Left. The HFSS Model used to Design and Analyze the Antenna is on the Right
