Abstract
Bandwidth, size and polarization optimizations of a single layer wide-band full and half E-shaped patch antenna fed through a coaxial probe are described. The finite-difference time-domain (FDTD) method was used in the simulations. Measurements and simulations using capacitive feeding and shorting pins are presented. Using these techniques, the bandwidth can be improved up to 32% and the antenna area can be reduced up to 60% without significant change in the frequency band. Using four raised conducting walls on edges of the ground plane, the cross-polarization level is improved. © 2010 Wiley Periodicals, Inc.
