Abstract :
Using inexpensive foam materials in the design of aperture-coupled patch antennas, large bandwidth and excellent cross polarisation properties can be achieved. This paper shows the mathematical treatment of such antennas using a spectral domain approach and the exact Green´s functions for multiple dielectric layers. The performance of a 16 × 16 element array for 12.625 GHz will be demonstrated.
