Abstract
A configuration of circular notch band monopole antenna with DGS structure is demonstrated in the present article. The proposed MSP antenna is feed by microstrip line feeding with circular radiating element on top side of FR4 substrate and defected ground structure on the lower side. The basic circular monopole antenna is initially designed to operate in the wideband (2.5–12 GHz) and the modified proposed antenna is oriented to operate as notch band antenna (7.5–8 GHz). In order to attain single notch band characteristics, square shape slots in the ground plane are used. Better gain characteristics of 4.9 dB are realized by placing defected ground structure in the antenna model.
