Abstract
In this article, circularly polarized microstrip patch antenna with a 5.8 GHz frequency for the Industrial Scientific Medical is designed and fabricated. The proposed modified crossโslots antenna composed four separate slots by removing the intersection of the crossโslot in conventional structure. The proposed antenna improved characteristics of the gain, radiation pattern, and impedance bandwidth than the conventional crossโslots antenna. As a result, the proposed antenna obtains impedance bandwidth of 240 MHz (VSWR < 1.5) and maximal gain of 5 dBi. ยฉ 2007 Wiley Periodicals, Inc.
