Effect of dielectric constant on the design of rectangular microstrip antenna

In this work, the effect of dielectric constant on the bandwidth of rectangular microstrip antenna (RMSA) operating at center frequency of 2 GHz is considered. The design of a rectangular microstrip antenna is made with different dielectric materials, the choice of material is based on materials that provide good antenna performance with reduced surface wave loss. Alumina 99.5%, Quartz (Fused) and Roger RT5880 are the materials for the proposed design to achieve a broader bandwidth. The design that gives voltage standing wave ratio (VSWR)≤ 2 is considered the best for the proposed antenna. The antennas are simulated using Sonnet lite software.
