Circular Disc Monopole Microstrip-Fed Antenna with Damaged Waveguide Structures
In a bid to enhance the performance of antennas, this paper presents a circular disc monopole microstripfed antenna with damaged waveguide structures which are constructed and analysed. By incorporating artful application of waveguide imperfections, the proposed antenna would aim at delivering wideband features as well as improvement of radiating properties. The electromagnetic simulation indicates that damaged structure of the waveguides can also lead to a better impedance matching and bandwidth. Experimental data confirms the validity of the simulation; it shows an improved gain and constant radiation patterns in the whole operation range of frequency. The compact size of the antenna, high bandwidth and efficiency renders the antenna suitable to a variety of wireless communication applications. When all is considered, a circular disc monopole microstrip-fed antenna integrated with damaged waveguide structures is a new alternative of maximizing antenna performance with maintaining a simple low profile design.
