Description |
This article proposes efficient high gain with low sidelobe level (SLL) antenna structures using circular array of square parasitic patches (CASPPs) for wireless applications. The antenna structure consists of a microstrip antenna that feeds a CASPP fabricated on a low cost FR4 superstrate. The patches on superstmte are suspended in air at about lambda(0)12. The structure with 19-element CA,SPPs is designed, fabricated, and tested. The measured VSWR is 20 dB. Antenna with CASPPs on finite ground requires 25% less ground plane size as compared to planar coral. The proposed structure can be packaged inside an application platform. (C) 2010 .
