Optimization Of Impedance Bandwidth For The Printed Rectangular Monopole Antenna, Matthias John, Max Ammann
Articles
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.

A monopole antenna, printed on low-cost laminate and fed by a microstrip line, is examined. These types of antennas are becoming popular in view of their broad bandwidth and low-profile structure, enabling easy integration as a terminal antenna. The move away from a classical ground plane (with normal radiator) is one of the attractive features of these antennas, but the full effects of the radiator and ground plane being on opposite sides of the same laminate are often not investigated. The effect of these ground planes on the impedance bandwidth and radiation pattern is investigated experimentally and numerically.
