Abstract
A planar dipole antenna is presented for ultrawideband applications. The proposed antenna consists of two patches forming a half-wavelength center-fed dipole. The differentially-fed dipole couples with an integrated balun-transformer and ground plane to achieve a stable broadside radiation pattern and consistent gain of 7.5-8.8 dBi. An impedance bandwidth from 3.1-4.8 GHz (43%) for a reflection coefficient of |S11 | <; -10 dB has been achieved.
