摘要

The electromagnetic surface antenna array(EMSAA)has been proposed for obtaining reflection suppression and ex-cellent radiation simultaneously.The antenna with rectangular radiation patch is used to design anisotropic electromagnetic surface.Preternatural reflection characteristics of the element antenna can be tailored depending on the incident polarizations.EMSAA can be constructed by using single structured element antenna with 90° rotation and orthometric arrangement.This or-thometric arrangement of EMSAA is helpful to achieve reflection suppression and excellent radiation.The simulated results show that the reflection of EMSAA is suppressed from 5.0 GHz to 8.0 GHz with peak reduction of 12.3 dB.The linear-and circular-polarized radiation properties of EMSAA are obtained and the maximum gain is 14.3 dBi.The measured results are consistent with the simulation results.The results demonstrate that the re-flection suppression and excellent radiation are achieved simul-taneously.Such design of EMSAA will open the path for integrat-ing antenna fields and electromagnetic surface(EMS)fields.
