Mutual influence reduction of dual band reflector backed dipole antenna using edge folded FSR

摘要

This paper investigates the effectiveness of the edge folded frequency selective reflector (FSR) structure in reducing mutual influence between low and high band radiation patterns of a dual band reflector backed dipole antenna (RBDA), which employs FSR in the high band RBDA. As the results of the moment method analysis related to the half-power-beamwidth (HPBW) and the front-to-back ratio (FB) characteristics of the RBDA, it is confirmed that the edge folded FSR structure is effective to reduce the radiation pattern distortion in both the frequency bands.
