Microstrip antennas are well known for its advantages such as light weight, low fabrication cost, mechanically robust and capability of dual and triple band frequency operation. These antennas are used in many modern communications systems such as personal communication systems, satellite and other wireless applications. This paper is to design wideband rectangular patch antenna printed on FR-4 substrate. Higher bandwidth can be achieved by unsymmetrical feed and a reduction in ground plane with proper gap distance. The rectangular patch antenna works from 1.4-4GHz at 95% bandwidth with a 2.1mm wide microstrip line feed.
