Ultra wide band monopole eliptical patch anteena

Abstract

Telecommunication industry has always competed against limited resources, various upcoming application and increasing number of users. This aspect has given a significance importance to the microwave radio band. Numerous telecommunication equipment and devices are operating in this band in today’s world. Ultra Wideband (UWB) Antennas are now becoming attractive tool for them as they can cover the large portion of microwave band. Telecommunications systems operating at various frequencies are currently using number of RF Antennas for provision of various services which are occupying range of frequency bands. The requirement of an UWB antenna which can operate on all frequencies of that particular system has gained significance. In recent times there has been an increase in the tendency of using UWB antennas for various applications in communication systems where the manufactures desire to have a single antenna that can it is desirable to have a single antenna that can cover an ultra-wideband. The project intends to develop an indigenous UWB antenna which can operate on a frequency range from 1-30 GHz. The project started with the design of single element monopole antenna with maximum gain and minimum losses. Later on series array design consisting of two monopole antennas and finally a corporate fed array design of four antennas with Wilkinson power divider are designed. Tapering technique is used in Wilkinson power divider to achieve the desired bandwidth in corporate array. The antenna design is initially simulated in HFSS and then was converted to an AUTOCAD file for fabrication.
