P Vijay Muni 01 02 In a bid to enhance the performance of antennas this paper presents a circular disc monopole microstripfedantenna with damaged waveguide structures which are constructed and analysed By incorporating artfulapplication of waveguide imperfections the proposed antenna would aim at delivering wideband features as well asimprovement of radiating properties The electromagnetic simulation indicates that damaged structure of thewaveguides can also lead to a better impedance matching and bandwidth Experimental data confirms the validity ofthe simulation it shows an improved gain and constant radiation patterns in the whole operation range of frequencyThe compact size of the antenna high bandwidth and efficiency renders the antenna suitable to a variety of wirelesscommunication applications When all is considered a circular disc monopole microstripfed antenna integrated withdamaged waveguide structures is a new alternative of maximizing antenna performance with maintaining a simplelow profile design Copyright (c) Journal of Engineering Technology and Sciences.
