DESIGN OF DUAL STUB LOADED MONO AND BI-PLANE CENTER-FED MICROSTRIP BOW-TIE ANTENNAS FOR WIRELESS APPLICATIONS

Abstract

Design approach of the extended model for dual-band operation of traditional frustoconical-shaped microstrip bow-tie antennas in mono and bi-plane topologies is presented and investigated numerically by simulations. Numerical investigations of the input characteristics are carried out using an electromagnetic approach based on transmission line theory in traveling-waves. Electrostatics approach solution is used to perform the calculation of the radiated electric field pattern. Some input and output performances of the designed extended model of the proposed antennas such as a dual-band, a -10dB return loss bandwidth of about 88%, a half power beam-width of about 90° and a stable gain of about 5.5dB have been achieved
