摘要

介绍了用于ISRA雷达的水平极化微带贴片阵列的设计。这项研究的第一步是设计一个单一的天线元件。为了增加增益和缩小波束宽度,然后将每个单天线布置为5×1和5×4。为了获得水平偏振,在底部贴片的右侧有一个矩形槽。天线阵由20个正方形贴片组成,在垂直和水平方向上均匀分布。结果表明,该天线阵的谐振频率为9.3 GHz,反射系数为- 31.93 dB。天线阵列的增益为17.9 dB,而垂直波束宽度和水平波束宽度分别为16.8°和21.4°。天线馈电使用接近技术,该技术利用两个基板,底部基板上的传输线和基板顶部的贴片天线。该技术可使天线带宽提高59.36%。

Microstrip patch array antenna with horizontal polarization for ISRA RADAR
The design of microstrip patch array with horizontal polarization for ISRA radar is presented in this paper. The first step of this research is designing a single antenna element. To increase the gain and to narrow the beamwidth, each single antenna is then arranged as the 5×1 and the 5×4. To obtain horizontal polarization, a rectangular slot is located on the right side of the bottom patch. Antenna array consists of a 20 squareshaped patch with uniform distribution to the vertical and horizontal directions. The results showed an antenna array has a resonant frequency of 9.3 GHz with reflection coefficient value of −31.93 dB. The resulting gain of the antenna array is 17.9 dB whereas the vertical and horizontal beamwidth antenna array is 16,8° and 21,4°. An antenna feeding uses a proximity technique which utilizes two substrates, the transmission line on the bottom substrate and the patch antenna on top of the substrate. This technique can increase the bandwidth of the antenna by 59.36%.
