Abstract

A Multi slot dual band with an ultra-wide band ‘T’ and ‘G’ slots shaped Micro-strip UWB Patch Antenna proposed has been discussed in this paper. The sizes of length & widths of the uwb-patch has been chosen and varied in such a manner that it occupies compact volume of 32 × 28 × 1.7 (1523 mm3) and it is designed on a substrate FR4-epoxy having a dielectric constant of εr = 4.4. The antenna is capable to operate in dual band with second band being a wide band ranging from 3.59 GHz to 10 GHz. The first band operates in 2.32 GHz–2.48 GHz range and is obtained by slot size variations in the ‘TG’ slot geometry. The advantages of the proposed ‘T’ and ‘G’ shaped slots design is that of the two band obtained, one ultra-wide band frequency range of operation can be achieved without the slots size variations using the same specifications or dimensions thus overcoming the need for extra enhancement of the surface area while designing the antenna. TG shaped Antenna is covering applications from ISM 2.4 WLAN Band, LTE band No 40 and wide band wireless applications in 5.2/5.8 GHz ISM WLAN, Radio altimeters (4.2 GHz) and Wimax (3.5/5.55 GHz). Direct probe feeding method using a 50 Ω micro-strip line has been used with the width 3 mm for the micro-strip line. The Coupling between the two slots plays a better role for obtaining the wider bandwidth. The analysis of the parameters such as directivity, bandwidth, return loss (dB), gain and VSWR (Voltage Standing Wave Ratio) of the Microstrip patch antenna with ‘T’ & ‘G’ slot has been performed using HFSS v15 [24] tool. The obtained return losses (RL) and the radiations patterns are found to be suitable for the LTE operations and moderately omnidirectional in nature. With the variation in the length (L) and width (W) in the ‘T’ & ‘G’ slots shaped geometry, the performance of uwb patch antenna has been studied with the comparisons of the simulated results in this paper.
