摘要

提出并研究了一种提高宽带缝隙天线阻抗带宽的设计方案。在50欧姆SMA连接器上采用有限地平面的宽带槽天线来提高阻抗带宽。天线的测量结果表明，天线的阻抗带宽与有限地平面的尺寸有关。通过适当调整有限地平面的尺寸，可以实现IEEE802.15.3a的超宽带(UWB)天线。对于10db的回波损耗，建议天线的带宽范围为2.3 GHz ~ 12ghz。增益变化从0.2到6.98 dBi。试验结果与仿真结果吻合较好。

Impedance Bandwidth Enhancement For UWB Slot Antenna

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.
