Abstract

This paper presents the concept of using a harmonic trap to design a wideband reconfigurable antenna. The reconfigurable antennas can be used to select one of a number of operating frequency bands. If these bands cover a very wide frequency range, then one of the higher‐frequency bands can be a harmonic of a lower band. When the antenna operates at the lower band, it can have a good match at the high frequency. This paper proposes a technique for designing a wideband reconfigurable printed dipole antenna so as to select only one of the operating frequency bands by using a harmonic trap. The antenna is designed, fabricated, and measured. It is shown that by using switches and harmonic traps, a reconfigurable printed dipole antenna can be designed over a frequency range of 3:1. The antenna is thus suitable for frequency switching in the FCC ultra‐wideband allocation. © 2006 Wiley Periodicals, Inc.

## Abstract This paper presents a wideband printed dipole‐antenna element. The broad bandwidth is achieved by optimization of the feeding network, which is implemented as a microstrip tapered balun. The design is based on double‐sided flat‐dipole implementation. The prototype antenna exhibits a mea
