This paper presents a low-cost ultra-wideband microstrip antenna for wireless communications. Printed on a 40times50times1.83 mm3 Isola Gigaver 210 substrate, the antenna features a microstrip feed line with two 45deg bends and a tapered section for size reduction and matching, respectively. The ground plane is partial and comprises a rectangular part and a trapezoidal part. The patch is a half ellipse,...
In this paper, a novel printed-circuit-board (PCB) antenna that employs electronic tunability is presented. The antenna is based on a 10 mm times 25 mm times 1.6 mm FR4-epoxy substrate, is microstrip-line fed and has a partial ground plane. The proposed antenna is designed and simulated using the Finite-Element Method (FEM) and the Method of Moments (MoM) for two different switching conditions. The...
This paper presents a new approach for the design of a multi-band bowtie antenna. By incorporating slots with different shapes and sizes on the arms of the bowtie, resonance is obtained in the 2.4 GHz, 3.5 GHz, and 5 GHz bands corresponding to Wi-Fi 802.11a, 802.11b, 802.11g , 802.11n, and WiMAX 802.16-2004 standards. A study of the effect of circular and triangular slots, their size and their location...
This letter presents a new approach for the design of a multiresonant printed bowtie antenna. Several techniques were attempted to obtain one antenna which is operational in the 2, 3, and 5 GHz bands corresponding to many wireless applications. The idea of creating different slot configurations on different parts of a single antenna is the basic principle. A prototype of the final antenna design was...
