Abstract

Design and analysis of a conductor-backed coplanar waveguide (CBCPW) fed circular coplanar patch antenna are presented and compared with microstrip line-fed one. Similar performances such as resonant frequency, gain, and radiation patterns are observed between them in both TM₁₁ and TM₁₂ modes. When via-holes are placed alongside the CBCPW feed-line and surrounding the circular patch, the side plane resonances could be eliminated, and the via-loaded design has a larger antenna gain and smoother radiation pattern than those without via-holes.
