Abstract :
A switchable ultra-wideband (UWB) to tri-band antenna with the presence of the three RF switches is presented. The proposed antenna capable to perform UWB at 2.7GHz to 11.9GHz and tri-band antenna at band 1 (2.43GHz to 2.65GHz), band 2 (3.18GHz to 6.58GHz) and band 3 (7.41GHz to 10.81GHz) under the minimum impedance matching of -10dB. The novel design antenna with a partial ground has a compact size of 38 mm × 38 mm. Furthermore, the simulated antenna gain demonstrates 5.5dBi for the high speed wireless digital communication system. The simulated of ideal switch fully reveal the performance of the projected antenna.
