Abstract

The gain of dielectric resonator antennas (DRA) above a ground plane is enhanced by placing a dielectric disc on top of the ground plane by a half wavelength. The dielectric disc is of a quarter dielectric wavelength thicknesses. This technique is also used to enhance the array antenna gain as well as reducing the number of the array elements by 75%. The dielectric slab acts as a lens as well as a Radom. A microstrip feeding network is used with all 50 Ohms microstrip lines with the 2 D arrays that reduce the feeding network discontinuities.
