A printed dipole with rotated tapered arms is of considerable interest as a broadband antenna element, and has good potential for use in low cost wireless base station (tri‐band TD‐SCDMA) antenna applications. The antenna which employs a planar reflector is composed of two tapered arms fed by an integrated balun and loaded with a lumped element (a 0.6 pF capacitor), leading to a broad impedance bandwidth and stable gains. The capacitor and the balun comprise the adjustable matching network. Measured result shows that the antenna provides an impedance bandwidth of 40% for voltage standing wave ratio (VSWR) less than 2. Good radiation performances and gains over the operating band are observed. Parametric study of its performance is also performed to provide more information for the antenna design. © 2011 Wiley Periodicals, Inc.
