The poposed antenna is designed on FR4-epoxy substate and the pefomance is obtained by using CST Micowave Studio. The antenna has been analyzed fo vaious dimensions of slots and the optimum design has been chosen. By inceasing the numbe of slots, the gain, bandwidth and etun loss of the stuctue has been impoved. The simulated antenna stuctues also show dual band chaacteistics. The antenna offes application in WiFi IEEE80.n (.4 to 5 GHz) and UWB ange especially fo X-band uplink satellite system ( GHz). As the designed stuctues esonate in C-band (4-8 GHz), it offes applications in Fixed Satellite Sevices (FSS) and militay also. Index Tems: Micostip Patch Antenna, Ulta Wide Band, Fixed Satellite Sevices, Retun Loss. I. INTRODUCTION As the demands of wieless systems have inceased day by day, low pofile systems have dawn the inteest of the eseaches towads the Micostip Patch Antennas []. The gowing wieless communication systems equie small size and compact antennas which have wide bandwidth than conventional antenna design []. In the design of communication systems of low-pofile, size of antenna is a most citical facto. Theefoe, miniatuization techniques ae used fo the design of diffeent kinds of antennas []. Multiband antennas povide an effective integation of seveal communication standads, in addition to low-cost and high data ate featues. Multiband antennas can be designed by feeding techniques [ 3], etching slots [4 6], adding multi-banched stips, factals etc. Slots ceate some sot of discontinuity in the electic cuent path leading to positive impact on input impedance theeby ceating additional esonance fequencies. Reseach shows that cutting slots and slits in adiating patch and gound plane [8-] shift the opeating fequency and incease esonating fequencies. The poposed antenna woks in the WiFi IEEE80.n (.4 to 5 GHz) and UWB ange especially fo X-band uplink satellite system ( GHz). This stuctue can also be used fo C-band (4-8 GHz) applications in Satellite communication and also fo medical uses to detect cances and tumos whee the safe fequency ange fo human tissues is 4 GHz GHz.

By inceasing the numbe of slots and deceasing the size of the slots, we can obseve that the gain of the poposed antenna has been inceased. The pape is divided into thee moe sections. Section II shows the antenna design, Section III shows the paametic study of hexagonal patch antenna and Section IV shows the paametic study of poposed antenna. A compaative study of hexagonal patch antenna with the poposed antenna with slots is discussed in Section V. II. ANTENNA DESIGN The micostip antenna consists of a vey thin patch placed above a gound plane. The patch can be of any shapes such as ectangula, cicula, tiangula. In this wok, the hexagonal patch with slots is selected fo the analysis. Although the tansmission line model yields less accuate esults, it is a vey simple model and povides a good physical insight of the basic antenna pefomance. Among the vaious feeding methods, micostip line feed is chose as it is simple to model and easy to fabicate. A. Design of Rectangula Patch The model of Micostip Antenna can be epesented by two slots of width (W) and height (h) sepaated by tansmission line of length (L). The width of the patch can be calculated fom the following equation [7]. v W 0 f The effective dielectic constant of the substate can be calculated as follows, () eff h W The actual length of the antenna is diffeent fom the calculated L since the finging field also needs to be consideed hee. The actual length is calculated by subtacting the excess lengths fom both the sides of the patch. The length of the Patch Antenna L is given by, W eff c h (3) L 0.84h f W eff eff h Highe values of pemittivity allow a shinking of the Patch Antenna. Paticulaly in cell phones, the designes ae given vey little space and want the antenna to be a half-wavelength long. One technique is to use a substate with a vey high pemittivity.

Using highe values fo pemittivity is fequently exploited in antenna miniatuization. The height of the substate h also contols the bandwidth - inceasing the height inceases the bandwidth. B. Design of Hexagonal Patch The aim is to design a patch shape othe than ectangle; a ectangula patch fo the paticula fequency is designed initially. The paametes of ectangula patch ae modified to obtain the dimensions of the othe patch shapes like cicula, hexagonal etc. The adius a of a cicula patch whose esonant fequency is f is given by, X mnc a (6) f Xmn =.8 fo T M mode The effective adius of the patch can be calculated as, h a a a ln.776 (7) e a h If the patch is hexagonal, then the sides of the hexagon can be calculated using the effective adius of the cicula patch.
