摘要：

A wideband and dual-band dipole antenna with an integrated Abstract-A wideband and dual-band dipole antenna with an integrated Abstract-A wideband and dual-band dipole antenna with an integrated balun feed is given. First, the antenna structure is optimized and a 41.5% bandwidth is obtained where voltage standing wave ratio (VSWR) is less than 2. In order to further get a larger bandwidth and dual-band capabilities of this antenna, some rectangle apertures are etched onto the antenna surface, and a better dipole antenna is fabricated. Through investigating rectangle aperture with different sizes, a 47.8% bandwidth is obtained at L-band, and a 15.1% bandwidth comes true at S-band. Agreement between calculations and measurements is very good. The result indicates that the novel design not only may obtain better wideband characteristic but also can let the dipole antenna work at L- and S-bands.
