Abstract :
An experimental investigation is presented on the impedance bandwidth of an electromagnetically coupled, probe-fed stacked annular-ring microstrip patch antenna. A bandwidth of 12.6% is achieved around a centre frequency of 2.38 GHz. Measurements on gain and radiation patterns are also presented. The antenna presented is suitable for use in planar and conformal arrays. It could find applications in the industrial, scientific and medical (ISM) frequency bands.
