Abstract

Compared to traditional antennas, microstrip antennas offer numerous advantages, such as low prices, low weight, ease of feeding, and attractive radiation characteristics. A microstrip antenna is a radiator covered with a dielectric cover layer for protection from rain, snow, and other environmental conditions. When placing the dielectric cover layer on the microstrip patch antenna, it effects the antenna parameters. In particular, the resonant frequency is lowered, causing tuning problems and severely degrading the antenna performance. This paper discussed the effect of cover layer thickness on antenna parameters such as resonant frequency, gain, bandwidth, beam-width, VSWR, return loss, and radiation patterns. The proposed patch antenna is designed for an S-band frequency of 2.4 GHz. The proposed antenna is used in wireless and bluetooth applications. This paper experimentally studies the effects of cover layer thickness on microstrip patch antennas.
