A Co planner Wave Guide (CPWG) fed with octagonal patch antenna is modified from their respective rectangular patch are presented for WLAN application. The dielectric material applied in the design process for both co planar and micro strip patch antenna is FR4 Epoxy Glass, which has relative permittivity of 4.4 and substrate height 1.6mm. Antenna parameters used to check the performance. A comparison is made between the octagonal co-planar antenna and octagonal micro strip antenna available. Ansys HFSS is used for antenna design and analysis. Both designed antennas are suitable for wireless local area network application and the design parameters of the antenna are optimized to resonate at 3GHz frequencies for WLAN applications. It has been found that octagonal micro strip patch antennas have lower return loss and are more directive than co planar patch antenna. High directivity of octagonal micro strip antenna is due to the presence of ground plane under the substrate of antenna. The results obtained by simulations have also shown that octagonal co planar patch antennas have high radiation efficiency (a measure of the power radiated through the antenna as an electromagnetic wave to the power fed to the antenna terminals) and which implies a wider bandwidth as compared to an octagonal micro strip patch antennas. The radiation efficiency obtained for micro strip patch antenna is 24% and that for co planar patch antenna is 67%, the directivity for micro strip patch antenna is 3.75 dB and that for a co-planar patch antenna is 3.25 dB.

Abstract: The performance of a microstrip patch antenna for a practical wireless local area network application is investigated in this research. This design is built around the transmission line concept. The antenna design substrate is FR4 (lossy) with a dielectric constant (Er) of 4.3 dielectric material, and the ground and patch materials are copper (annealed). The substrate is 71.62mm in width and 55.47mm in length. The height of the dielectric material is 1.6mm, which is the normal size for FR4 material. The conducting patch element has a width of 35.81mm and a length of 27.73mm for a resonance frequency of 2.573 GHz. A simulation with CST studio suite was used to optimise the antenna design.

Novel Method

This paper proposes a unique, first of its kind fabrication technique for the making of textile antennas. A novel method that provides scope for automation in textile antenna production is presented here. A completely integrated textile antenna fabrication method that eliminates the tasks of positioning and fastening of the various components of a patch antenna is discussed. The technique employs multilayer weaving for the production of a wearable antenna on a cotton substrate. Silver yarn is used for the conductive regions of the textile antenna. Two layers of woven cotton serve to isolate the radiating patch from the ground plane of the antenna. The designed antenna was chosen to operate at the frequency of 2.45 GHz for Wireless Local Area Network. The built prototype resonated at 2.43 GHz with a |S11|of −18.62 dB. The integrated textile antenna exhibited a gain of 1.06 dBi at 2.43 GHz.
