Abstract—This paper presents, a compact coplanar waveguide (CPW) fed frequency reconfigurable antenna integrated with PIN diode. The electrical length of the radiating patch is modified due to diode which acts as a switch in proposed antenna system with proper biasing circuit. The prototype of design is made on FR-4 substrate. The antenna parameters; return loss, gain and radiation pattern have been presented for validation of antenna characteristics. The operating frequency ranges of the antenna are 3.1 to 3.6 GHz, and 6 to 8.8 GHz in ON state while 3.8 to 5.05GHz and 7.55 to 9 GHz in OFF state of diode respectively. The obtained results reveal that proposed antenna could be very useful for 5G and specific UWB applications.
