Abstract

This paper describes a new low‐profile X antenna array separated 0.1–0.15 wavelengths from a flat or rimmed square reflector of 0.6 wavelengths in size. The array consists of two closely spaced elements: an active two‐port folded‐wire X antenna, which radiates two cross‐polarized fields and a passive X element. This very compact double X reflector antenna has around 8–9 dBi peak directive gain, 12.5% bandwidth on average around the design frequency of 1800 MHz, a high interport isolation (about 25–30 dB) and low cross‐polarization in the whole input‐match frequency range. The practical applications of the properly designed and tuned double X reflector antenna may include among others, base station antennas with polarization diversity for GSM PCS or DCS bands, or for the whole UMTS band. © 2010 Wiley Periodicals, Inc.
