Modified Wang Shaped Ultra-Wideband (UWB) Fractal Patch Antenna for Millimetre-Wave Applications

Abstract

In this work, a microstrip line fed ultra-wideband (UWB) modified Wang shaped fractal patch (MWFP) antenna has been proposed. The parameters of the MWFP antenna such as operational bandwidth, efficiency, gain, and radiation pattern have been examined numerically. Four bands, 14.8-16.3 GHz, 19.6-21.5 GHz, 32.65-36.1 GHz and 40–160 GHz, are achieved. The operational bandwidth of the fourth band is from 40–160 GHz (U, V, E, W, F & D bands) which shows the fractional bandwidth as 120%, stable gain around 9.81 dB, efficiency of 80% and VSWR less than 1.8. The examined characteristics show that the proposed antenna is a good candidate for the applications of millimetre-wave.
