Abstract :
Dielectric antennas have proved their utility in higher frequency ranges due to low loss, light weight and high performance. Rectangular slab is the commonest dielectric antenna configuration used for diverse applications like mobile and satellite communication, missile guidance etc. Its directivity has been improved by introducing a truncated hollow pyramid in front of the antenna which also resulted in improvement of return loss and VSWR bandwidth appreciably. Computer simulated results are presented for the novel dielectric slab antenna with a pyramidal tapered wave launching section fed by a rectangular metallic waveguide.
