提出了一种新型2×2微带天线阵列。该阵列中使用的元件是齿状槽贴片。该贴片通过微带馈线进行电磁耦合。除了易于馈电外，所提出的结构还具有宽带宽、高增益和低交叉极化水平的优点。该贴片元件的峰值增益为10.2 dBi，并且在阻抗带宽内交叉极化低于-23 dB。测得2×2阵列的VSWR表明阻抗带宽为34%。该阵列的增益在 4.8-6.1 GHz 时为 14-16.3 dBi。并且在阻抗带宽内阵列的交叉极化电平低于-20 dB
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
