Abstract
In this letter, a new substrate integrated magneto–electric dipole (ME) antenna has been proposed for ultrawideband application. The proposed antenna is composed of a bowtie patch functioning as an electric dipole and a pair of circular vertical shorted vias that are equivalent to a magnetic dipole. A Γ-shaped probe feed is employed to excite the ME antenna, and some planar metal reflectors with shorted via holes are located at the corner of the antenna to improve matching and radiation pattern of the antenna. A prototype was fabricated and measured. The simulation and measurement results demonstrate an impedance bandwidth of 110% with SWR≤2 from 3.1–10.66 GHz and a stable gain of 8.4 ± 2.5 dBi. Good unidirectional radiation patterns with low back radiation and low cross-polarization radiation are achieved across the operating bandwidth. With the use of multilayer printed circuit board technology, the proposed ME antenna is low-cost and easy to fabricate.
