Compact printed hexagonal ultra wideband monopole antenna with band-notch characteristics

This article presents a compact, printed hexagonal monopole, ultra wideband antenna along with band-notch characteristics. The proposed monopole antenna consists of a printed hexagonal radiating element and a defected ground structure. Printed round-slot geometry and defected ground structure play a vital role in achieving the ultra wide bandwidth. Band-notch characteristics for eliminating the interference arising from the existing WLAN (5.15 – 5.825 GHz) band has been incorporated in the antenna frequency response by the insertion of C-shaped stubs near the feeding segment. The antenna shows a decent gain of ≥ 3.0 dBi throughout the entire bandwidth except at the notched frequency band. Measured results agree well with the simulated values

Investigations on a low-profile, filter backed, printed monopole antenna for UWB communication

106-112A compact, printed dual band-notched, filter backed antenna or filtenna, with suppressed radiation characteristics outside the ultra-wide frequency band (UWB) has been scripted in this manuscript. The filtenna has been designed to work in the UWB frequency domain (03.1 - 10.6 GHz), as prescribed by federal communications commission (FCC). Band-notching structures have been incorporated in the radiating element for realization of dual band- notches for WLAN and WiMAX. The novelty lies in the fact that, a microstrip band pass filter has been introduced in the antenna feeding section for improvement of the cut-off frequency and frequency selectivity. An impedance bandwidth (S11 ≤ -10.0 dB) of 03.1 - 10.6 GHz has been obtained excepting two frequency-notches having centre frequencies of 03.5 GHz and 05.5 GHz, respectively. Promise able simulation results followed by measurement, justify the applicability of the novel filtenna for UWB communications
