Abstract

The RFID systems are used more and more widely, and the low profile and low cost antennas are strongly needed for some base stations. Here a novel 3D miniaturized RFID antenna is proposed. It consists of two vertical printed triangular monopole antenna elements. And top-loading is used to reduce the antenna´s profile. Four tuning poles are adopted for better matching and broader bandwidth. The measured return loss is -33dB and its -10dB bandwidth is about 20%. The measured maximum gain is 3.73dB. Compared with conventional RFID antenna, 50% size reduction is achieved.
