Abstract :
A design for enhancing impedance bandwidth of wideband slot antenna is proposed and studied. The wideband slot antenna with a finite ground plane on the 50 ohm SMA connector is used for enhancing the impedance bandwidth. The measured results of the proposed antenna show that the impedance bandwidth is related with dimensions of a finite ground plane. By properly adjusting the dimension of finite ground plane, the antenna of UWB (ultra wideband) for IEEE802.15.3a can be achieved. For the 10 dB return loss, the bandwidth of the proposed antenna is from 2.3 GHz to 12 GHz. The gain variation is changing from 0.2 to 6.98 dBi. The test results agreed well with those of simulation.
