Abstract
Description
Different dielectric materials affect the electrical characteristics of a patch antenna differently. In this paper, the
design frequency and the thickness of the substrate were kept constant, while different substrate materials were used in the
design of an inset fed rectangular patch antenna in other to study the effect of these substrate materials on the Gain and
radiation pattern of the antenna. Substrate materials like FR4 with dielectric constant of 4.4, Duroid (tm) with dielectric
constant of 2.2, Foam with dielectric constant of 1.05 and Neltec NH9348 with dielectric constant of 3.48 were investigated.
The antenna was designed and simulated using HFSS software. The result obtained shows that foam, with the least dielectric
constant has the highest gain with a wide beam radiation pattern, followed by Duroid, while FR 4 has the least gain.
