Band widening technique for small integrated packaged antennas

Abstract

In this work a different approach to widen the bandwidth of an electrically small antenna is proposed. Unlike other methods reported in literature the idea explored here uses the feeding network to improve the bandwidth. The methodology is illustrated using a circular patch antenna for testing purposes, but there is no fundamental reason why this approach would not work for other types of antenna. All presented results were obtained from full wave simulations of the antenna structure using commercial software.
