[IEEE 2018 International Conference on Microwave and Millimeter Wave Technology (ICMMT) - Chengdu, China (2018.5.7-2018.5.11)] 2018 International Conference on Microwave and Millimeter Wave Technology (ICMMT) - A Novel Circularly Polarized Yagi Antenna

摘要： This paper presents a novel circularly polarized Yagi antenna, consisting of a reflector patch, an oscillator patch, two director patches and two conductor rings. Through the use of Yagi antenna structure and conductor ring structure, antenna gain has been improved. The simulation results show that the antenna has a gain of about 9dB, which is about 4dB higher than that of the existing patch antenna.
