This paper presents a study of a novel monopole antenna for ultra wideband (UWB) applications. Printed on a dielectric substrate FR4 and fed by a 50 microstrip line, a planar circular monopole has been demonstrated to provide an ultra wide 10 dB return loss bandwidth with satisfactory radiation properties. A T-shaped slot, cut in the radiating patch, increase the impedance bandwidth of the proposed antenna up to 131%. The parameters which affect the performance of the antenna in terms of its frequency domain characteristics are investigated. The proposed antenna is optimized by ANSOFT High Frequency Structure Simulator (HFSS). Details of the proposed antenna design and simulated results is described and discussed.
This paper presents a design of compact triple-mode resonator with Defected Ground Structure. This resonator consists of a square open-loop half-wavelength resonators and a stepped impedance resonator structured in the middle which is connected to the mid
