摘要
A novel double-printed rectangular patch dipole antenna suitable for UWB application is presented and investigated in this article. The effects of some important antenna parameters on the return loss of the proposed antenna have been investigated. Printed on the dielectric substrate and fed by a microstrip line, the antenna has been demonstrated to provide an UWB with return loss less than -10 dB from 3.1 to 10.6 GHz and the satisfactory radiation properties. A gain variation from 4.78 to 7.89 dB is obtained. The transfer function has flat magnitude and linear phase with smooth group delay being gained, which is advantageous to the transmission of the UWB signals.
