Design and Analysis of Novel Integrated Antenna Using Band Pass Defected Micro strip Structure (DMS) Filter

Abstract

This paper shows the design of multiband antenna that can be reconfigured for five different frequencies without any changes in resonant modes. This reconfigurability is done by band-pass filter that is integrated on the feedline of the antenna. Filter is of Tshaped defected structure with switches which helps in switching the frequency. This structure consists of dual sided tapered antenna which helps in remaining very less distortion. This type of antenna can be used for application like cognitive radios which makes use of free white space available on the spectrum. This novel antenna is simulated using Ansoft High Frequency Structure Simulator (HFSS) fabricated and tested.
