ABSTRACT
A single-layer single-patch wideband microstrip antenna could be developed, and impedance bandwidth greater than 30% can easily be achieved for a microstrip antenna with a probe feed, A broad-band design of a probe-fed rectangular patch antenna with a pair of wide slits is studied, and the simulated, radiation characteristics are studied. The proposed design is with an air substrate of thickness about 8% of the wavelength of the center operating frequency, the proposed antenna have an impedance bandwidth about 31.32%, with respect to center frequency. For frequencies within the impedance bandwidth, good radiation characteristics are also observed, with a peak antenna gain about 9.3 dBi.  in this paper the wide slits are inserted at one of the radiating edges of the rectangular patch and increasing the length, width of slits and reducing the distance between them upto the specific limit the, proposed design has achieved the wide impedance bandwidth and good radiation characteristics details of the proposed antenna and Some simulation results obtained by IE3D and are given.
