Abstract
In this paper, the characteristics of numerous types of artificial magnetic conductor (AMC) surface structures are investigated on high-frequency structure simulator (HFSS) and presented. These AMC surface structures are presented with zero-degree reflection phase property for a plane wave at 28 GHz frequency band. The ±90° in-phase reflection bandwidth, magnitude, and surface impedance of all AMC structures are simulated and compared with others. The simulated results show that all AMC surfaces act as a high impedance surface and good reflector. The simulated fractional bandwidth of proposed AMC type I, II, III, and IV structures are 4.68%, 7.12%, 9.03%, and 20.64%, respectively. The better performance of the proposed AMC type IV makes it as useful to improve the antenna’s characteristics.
