Reconfigurable Planar inverted F Antenna for Cognitive Radio & Mobile Systems
Abstract— This paper proposes a method of controlling the operation of the frequency reconfigurable planar
invert F antenna (FRPIFA antenna) by FPGA. In order to tune the antenna operating frequency, the operation
of PIN diodes – electronic switches are carried out through switches present in the FPGA board rather than a
predefined code, which provides high flexibility for testing & performance. A very low return loss & hence
low VSWR values is obtained. We were able to tune to frequencies as low as 766 MHz and frequencies as
high as 8.4 GHz. It also covers the ISM band. This can be used in cognitive radio module as a reconfigurable
antenna.
