Abstract
A simple wideband magnetoelectric dipole antenna with a defected ground structure (DGS) is proposed and investigated. The dimensions of the pair of the quarter-wavelength patch antennas and the half-wavelength electric dipole antennas are changed to extend the impedance bandwidth. A defected ground structure is used for impedance matching. A prototype of the proposed antenna is designed, fabricated and measured. Combining of impedance bandwidth and radiation pattern, measured results show that the proposed ME dipole antenna achieves an operating bandwidth of 86.9% (1.38-3.5 GHz) for |S11| < -10dB, and a stable gain of 7.2 ± 1.2 dBi is realized. Low cross-polarization level and low backlobe radiation level are found across the operating bandwidth.
