fringing field in microstrip patch antenna design

Ground plane are safe because the dimensions of the patch are limited along its length and its weight the em field at the patch edges undergo fringing. The dimensions of both the slots of patch and In third shape a similar h shaped slot has been taken out from the ground plane of the proposed antenna that forms defected ground structure. the introduction of slot in structure increases the electrical length of the antenna. The dimensions of slots are l= 20 mm and w = 28 mm. the presented second antenna structure has H shaped slot on patch in its design which account for its small size and lower cost. The height is a small sized planar patch antenna, the that has its length, L = 24mm and width W =32mm. The antennas have been design with fr4 substrate having height of 1.6mm.

In this paper a small size microstrip antenna with slot and defective ground structure have been designed to examine the relationship between the resonant performances of these antennas. Defect in ground plane helps in increasing capacitance and inductance. 05 wavelength) microstrip antennas have got great applications in military missiles Rockets, aircrafts and satellites defected ground structure is etched periodic or non periodic cascade defects in ground plane of microstrip antenna. microstrip patch antenna comma because of its small size, low profile, Low building cost and ease of working with feed networks are extensive applications in wireless communication system. the demand of introducing compact emptiness. Increasing demand to combine different Technologies into Micro equipment has greatly increased. There is a remarkable progress going on in wireless communication system. KeywordsDGS, microstrip antenna, return loss, gain. But also has an advantage of low cost and small size for S band C band and X band wireless applications As a result this new antenna exhibits multiband behavior and Better resonant characteristics than its original structure the proposed antenna not only has characteristics of good radiation. It is observed that a size reduction of 55.66% has been achieved by taking out an h shaped slot from both the patch and ground plane.
