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.
