A miniaturized printed UWB antenna with dual notching for X-b and and aeronautical radio navigation applications

Abstract

A low cost miniaturized ultra-wideband (UWB) microstrip antenna with dual notched band for X band and aeronautical radio navigation (ARN) is presented in this article. The antenna (19×25 mm 2) is composed of a half-circular ring as a radiation patch with an incomplete ground plane. The measured results indicate a fractional bandwidth of 112% for 11 ≤ −10dB between 3 to 10.6 GHz. The dual notched band has been achieved by incorporating window shaped microstrip closed ring resonators at the rear surface of the designed structure. The first notch band is centered at 7.5 GHz (7-8.1 GHz) to reject interference with X-band downlink (7.25 to 7.74 GHz) and second band centered at 9.1 GHz (8.6-9.4 GHz) to reject interference with ARN (8.7 to 9.2 GHz). The simulated and measured return loss, radiation pattern, and gain shows good agreement which confirms the applicability of the designed antenna for the intended UWB applications.

Graphene based rectangular microstrip patch antenna for UWB applications

“…Graphene's high speed, enormous carrier mobility, and low power consumption make it an ideal material for electronic devices. Because graphene has high carrier mobility, the SPP wave has an optimal path in graphene [27]. SPP wave propagation in the THz frequency band makes Graphene-based antennas easier to operate.…”
