Abstract :
Bandwidth and size optimisations of a single layer wide-band E-shaped patch antenna, fed through a coaxial probe are described. Maxwell equations are discretized and solved using the finite-difference time-domain (FDTD) method Simulations and measurements 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.
