Wideband highly-efficient transparent/miniaturized antennas using clear colorless acrylic sheets for space/WLAN applications

Abstract

Two novel resonator antennas are proposed for space/WLAN applications. The whole antenna system including substrate and resonator element is realized using clear colorless acrylic sheets. The first antenna is over 90% optically transparent and covers the entire Ku frequency band for satellite communications. By changing the boundary conditions using metallic plates, the second plastic antenna with significant size reduction is achieved to operate at 5-6 GHz frequency band for WLAN applications.
