Abstract

Two configurations of broadband microstrip antennas are proposed and analyzed numerically by the full-wave spectral-domain method. One is a square Archimedean spiral microstrip antenna which yields circular polarization; the second configuration is a log-periodic patch microstrip antenna, which radiates linearly. In this paper, the definition of bandwidth of an antenna is redefined and is based on both VSWR and radiation pattern behavior. A 25% bandwidth for a square Archimedean spiral microstrip antenna and a 2:1 bandwidth for a log-periodic patch microstrip antenna are achieved using electrically thick (1/8λ to 1/4λ) substrates. © 1993 VSP.
