Abstract - In this article, the rectangular multiband
Microstrip patch antenna is introduced. Here one cross slot in the patch is used to produce different resonant frequencies. The correct probe feed location is decided by parametric method give the promising results. The interesting features of proposed structure are that we get a multiband response in the frequency range 2.54GHZ2.67GHZ, 5.11GHZ-5.26GHz and 5.8GHZ-6GHZ which has applications for IEEE 802.11a and IEEE 802.11b WLAN.

1. INTRODUCTION In the modern wireless communication devices, the most important device to develop wireless communication link is an antenna. Microstrip patch antennas fulfill these requirements. These antennas have been used in an increasing number of wireless communication systems because of their simple structures, low weight and their production of low-profile, broadband radiation patterns. The selection of the size of length and width of the patch and materials of the substrate is most important part of designing desired antenna [1-2].To increase the bandwidth either slit or slot should be made on the ground plane. The compactness of the antenna is done by embedding slots in the correct position on the radiating patch [3-4].
of dielectric constant 4.4 have a tangent loss (tanᵟ) =0.02 and thickness is 1.6mm. The inner and outer diameter of the feeding probe is 1mm and 3mm respectively. The performance of reference antenna is optimizing using change the position of the slot on patch and ground plane and dimension is given in table 2.

In this article, the rectangular multiband Microstrip patch antenna has been proposed. In this proposed antenna the close ended rectangular slot is inserted in the ground plane. The radiating patch is generally made by any conducting materials and it can be any shape like a rectangle, triangle, circular and elliptical. After inserting a cross slot in the patch it creates a slow wave effect and shifted in lower band frequency which is applicable for WLAN.
