Abstract
We presented a miniaturized patch antenna with enhanced bandwidth. Reactive Impedance Surface (RIS) was introduced instead of the traditional metal floor, and bandwidth enhancement is realized by loading slotted parasitic patches. The reference antenna and the antenna 1 loaded with the parasitic patch are designed, that impedance bandwidth changed from 8.5% to 23.6%, the peak gain and the front-to-back ratio was also improved by 2.2dBi and 7.8dB respectively; The metal floor of antenna 1 was instead by using RIS periodic structure to design Antenna 2. The absolute bandwidth of both antenna 1 and antenna 2 is about 1GHz. Antenna 2 is 22.4% smaller than the reference antenna and 28.6% smaller than antenna 1. The simulation results show that the proposed bandwidth enhancement and miniaturization methods are effective and ensure a certain improvement in gain.
