Abstract

This paper presents the design and study of a high performance microstrip rectangular patch antenna for the 2.5 GHz ISM band. The proposed antenna make use of small multiple circular slots embedded in the radiator to enhance the performance of the traditional patch antenna. Introduction of the new multi-slot arrangement offers a low profile antenna with reduced size, improved impedance matching, broadband operation. A comparatively wider -10 dB impedance bandwidth of 95 MHz is achieved. The maximum achievable gain is 6.8 dBi.Good performance, light weight, mechanically rugged and inexpensive design make this antenna a potential candidate for wireless portable devices.
