Abstract

This paper discusses the design of a ring coupled rectangular microstrip patch antenna at a design frequency of 2 GHz for wireless applications. Additionally the effect of U-shaped slot on ring and centre path is also studied. The microstrip patch antenna is excited using strip line feeding method. The antenna is mounted on a FR-4 glass epoxy substrate. The antennas are designed and simulated using Mentor Graphics IE3D simulation software. The antennas have been fabricated and the measured results agree with the simulated results. Highest bandwidth and sizable virtual size reduction of 12.54 and 20.53 % are obtained.
