Design of the Triple Photonic Crystal Fractal Slot Array Antenna

Abstract

According to the performance requirements of the antennas for the multi-band compatible mobile communication system and RFID system, a novel triple photonic crystal antenna is proposed creatively, and combined with the cross fractal slot array structure, a triple photonic crystal fractal slot array antenna is designed, and the antenna samples are made and tested. According to the test results of antenna samples, this antenna can work in the frequency bands of the 2G, the 3G, the 4G and the 5G mobile communication system and three working frequency bands of RFID system at the same time, and has a large working bandwidth and strong radiation power in each working frequency band. This antenna has high stable radiation characteristics in all working frequency bands and is expected to be used in mobile phones with RFID reader and writer functions.
