Abstract

In this paper, a high-gain annular ring with meander slots antenna array is presented. The proposed design is realized on two different substrate materials separated by a foam layer of 7.5 mm to enhance the operating bandwidth. The antenna is designed to operated as UHF-RFID reading antenna over center frequency of 915 MHz with operating bandwidth of 49.25 MHz (around 5.38%). The overall antenna optimized dimensions are 240×240×11.56 mm3. An overall total realized gain of 12.5 dBi is achieved at the intended center frequency. The proposed antenna exhibits stable radiation capabilities over the operating band. Good agreement is obtained between both CSTMWS, and HFSS simulators.
用于RFID应用的高增益环形弯曲槽天线阵列
本文提出了一种高增益环形弯曲槽天线阵列。该设计是在两种不同的衬底材料上实现的,由7.5 mm的泡沫层隔开,以提高工作带宽。天线设计为UHF-RFID读取天线,中心频率为915 MHz,工作带宽为49.25 MHz(约5.38%)。天线整体优化尺寸为240×240×11.56 mm3。在预期的中心频率下,实现的总增益为12.5 dBi。该天线在工作频带内具有稳定的辐射能力。在CSTMWS和HFSS模拟器之间得到了很好的一致性。
