Fox-Face Compound Reconfigurable Antenna for Wireless Systems

A compact multiband Fox-Face compound reconfigurable antenna is proposed in this paper using two PIN diodes. On switching the states of the PIN diodes, the reconfigurable antenna resonates at multiple bands, having one band in each case for which the bandwidth is highest and is considered as the primary band. Primary frequency band is reconfigurable from 5.5GHz (used in 5G services) to 6.7GHz (used in digital high-capacity fixed point-to-point links), while a secondary band is present at around 9GHz (used in satellite and military applications) in all the four configurations possible in the design.
