Frequency Agility using Gunn diode on a Rectangular Microstrip Antenna

Abstract

With the advancement of science and technology in the field of wireless communication ,microstrip antenna is considered a versatile antenna .Apart from increasing its limitation of narrow bandwidth by active devices ,the operating frequency of loaded antenna can be controlled by the bias voltage of active devices .In this paper the active device is a Gunn diode and using equivalent circuit concept the analysis it on loading on Rectangular microstripantenna reveals that it offers wider tunability (9.9 GHz-10 GHz) for bias voltage from 8-15V for a given threshold voltage of 2.9 V.
