A Microstrip Line Fed Hexagonal Square Shaped Fractal Monopole Antenna for Ultra-Wide Band Applications

A compact hexagonal-square shaped fractal monopole antenna is etched out from circular patch for ultra-wide band application. This proposed antenna has an overall physical dimension of 54 × 35 mm2.The parameters of antenna such as Return loss, percentage Bandwidth, VSWR, E-plane and H-plane pattern, Gain, are analyzed. The partial ground plane and microstrip transmission line is employed to achieve ultra-wide band (UWB) operating bandwidth from 2.1 to 13.5 GHz (155%) with reflection coefficient close to −30 dB. This makes it suitable for the commercial, aerospace, and military telecommunication besides the traditional radar imaging application. The proposed antenna is fabricated. The simulated and measured outcomes are in very close agreement.
