Abstract
A wideband multiple-microstrip dipole antenna with
dual polarization is proposed in this letter. The antenna consists of
a radiator, a cross-shaped slot coupler, a pair of microstrip baluns,
and a reflector. When baluns are excited, the cross-shaped slot
coupler would work as a four-way equal-split power divider and
generate four differential signals at four ends of the slotlines. Afterward, the signals would be coupled to four modified dipoles to
radiate and synthesize slant ±45° linear polarizations. The proposed design is verified by the fabrication and testing of a prototype antenna. Measured results agree well with the simulated
ones, giving a wide impedance bandwidth from 1.68 to 2.75 GHz,
a high port-to-port isolation (better than 37 dB) within the operating frequency bandwidth, and a good radiation pattern. Besides,
the proposed antenna maintains a compact structure measuring
0.78λ0 × 0.78λ0 × 0.18λ0 .
