Abstract

In this paper, a compact design and construction of microstrip Ultra Wide Band (UWB) antenna is proposed. The proposed antenna has the capability of operating between 1.8GHz to 12GHz. Bandwidth enhancement is required for practical application of microstrip antenna for wireless communication. Enhanced bandwidth supports high speed of data communication. The antenna parameter in frequency domain analysis have been investigated to show its capability as an effective radiating element. The designed antenna has a compact size of 47mm * 36mm * 1.6 mm. The simulation results demonstrated good ultra wide band linear transmission performance. The highest efficiency claimed 92% at 2 GHz and minimum efficiency is 70%.The claimed bandwidth from proposed antenna is 2.1 GHz to 10 GHz that is 7.9 GHz. Bandwidth obtained with the proposed design is very good to incorporate all applications of UWB band.

Abstract

The microstrip patch antenna is one of the most preferred antenna structure for low cost and compact design wireless system and RF application. In this paper, various design are suggested and analysed for different height of different substrates for rectangular patch antenna (RPA) operating at 3 GHz as centre frequency. Using transmission-line model, analysis was done for the behaviour of the antenna for different types of substrates, modified thickness, patch geometries and shifted feeding point. This design of RPA is made to several dielectric materials for different thickness and the selection is based upon which material gives a better antenna performance with reduced surface wave loss. The result shows that Polyguide and RT Duroid 5880 for the thickness of 2.7 mm are the best materials for proposed design to achieve an enhanced Bandwidth (BW) and better gain with lower value of VSWR. The characteristic of the patch antenna are analysed by the MOM using Feko EM solution software version 6.0.
