Abstract

This letter presents the design and performance measures of a printed dipole antenna with band rejection characteristics for ultrawideband (UWB) applications. The proposed antenna operates in the frequency range 3.65615.64 GHz with impedance bandwidth of 11.027 GHz and maximum gain of 6.046 dBi. It consists of five dipole strips of different resonant length combined orthogonally for effective signal reception. Inverted L-shaped slots were introduced in the ground plane for WLAN band rejection. The band rejection is from 5.066.012 GHz. The radiation pattern is nearly omnidirectional in both the elevation and azimuthal plane due to the orthogonal configuration of the dipole strips. The consistency of the radiation pattern exists within the operating band. The performance of the proposed antenna is confirmed by simulation and experimental method.
