Microstrip Antenna Design for Ultra Wideband Application by Using Two Slots

摘要：

This paper presents a multiresonator microstrip antenna using a rectangular patch located on top of two slots, with different lengths and excited by a U-shaped feed line. The patch and slots are separated by a substrate with low dielectric constant and an air gap. The results show that the bandwidth of the antenna increases by using two slots. Finally an antenna with VSWR< 2 from 9.8 GHz to 22 GHz and 6.1 GHz (42％) gain bandwidth (above 7 dB) is obtained. The simulated gain of the antenna is over 5 dB from 9.8 GHz to 19 GHz and with a maximum gain of 9.16 dB at the frequency of 14 GHz.
