摘要
A compact and wideband printed dipole antenna is presented for C- and X-applications. The proposed balun-fed antenna consists of a double-sided printed dipole structure with a microstrip-fed modified spiral-dipole printed on the top side of the substrate, and a capacitive-coupling rectangular-patch, a connecting strip line and the ground plane printed on the bottom side. For the proposed antenna, a wide resonant band which extends from 6.2 7 to 12.4 7 GHz, with a fractional bandwidth of 66%, is observed. Details of the experimental and simulation results are presented and discussed. (C) 2008 Wiley Periodicals, Inc.
