Abstract

A new 2 times 2 microstrip antenna array is presented. The element used in this array is a tooth-like-slot patch. This patch is electromagnetically coupled by a microstrip feed line. In addition to the easy feeding, the proposed structure possesses the advantages of being wide bandwidth, high gain and the low cross-polarization level. The patch element has the peak gain 10.2 dBi and the cross-polarization is lower than -23 dB within the impedance bandwidth. The measured VSWR of 2 times 2 array show that the impedance bandwidth is 34%. The gain of the array is 14-16.3 dBi at 4.8-6.1 GHz. And the cross-polarization level of the array is lower than -20 dB within the impedance bandwidth
