Optimization of impedance bandwidth for the printed rectangular monopole antenna

Abstract

This paper describes a printed rectangular-plate monopole fed by microstrip line. The effect of varying the plate width, feed-gap height, and feedline width on the impedance bandwidth is examined. It is shown that for a fixed ground-plane size, that optimization of these parameters can yield an impedance bandwidth ratio of 4.3:1, without using any broadbanding techniques. © 2005 Wiley Periodicals, Inc.
