Effective Microstrip Feed Line Length in Ultra-Wideband Responses and Wireless Applications

Abstract

In this article, an effective feed line technique is used instead of DGS (Defected Ground Structure) and CSRR (Complimentary Split Ring Resonator) which are commonly used for achieving UWB (Ultra-Wideband Applications) responses. A classical antenna is designed for 2.4GHz frequency with a feedline of 180° electrical length. The resonance of proposed antenna responses as UWB and it has interesting current distributions through the patch antenna. This paper avoided all aspects of existing techniques which are proposed to achieve UWB.

High Gain Compact UWB Antenna for Ground Penetrating Radar Detection and Soil Inspection

“…When the feed-line width is around 1 mm, the optimum BW is obtained. The impedance BW of the antenna is degraded, especially at the middle of the working BW when the width exceeds 1 mm (the references regarding the theory of the impacts of feed-line width and length are [ 25 , 26 , 27 ].…”
