Design of a 3-D Integrated Wideband Filtering Magneto-Electric Dipole Antenna
A new design of 3-D integrated wideband filtering magneto-electric dipole antenna with high selectivity is presented. The proposed antenna is mainly composed of a horizontal planar dipole and a vertically oriented shorted patch antenna. A pair of C-slots is etched on the planar dipole to obtain shar...

A new design of 3-D integrated wideband filtering magneto-electric dipole antenna with high selectivity is presented. The proposed antenna is mainly composed of a horizontal planar dipole and a vertically oriented shorted patch antenna. A pair of C-slots is etched on the planar dipole to obtain sharp skirt selectivity near both band-edges. In addition, a slotline loaded with the patch antenna provides good impedance matching. The proposal exhibits a quasi-elliptic gain response with three introduced radiation nulls without additional filtering circuits. To verify the design concept, a prototype is fabricated and measured. The result exhibits an impedance bandwidth of 55.4% with <inline-formula> <tex-math notation="LaTeX">$\text {SWR}\le 1.5$ </tex-math></inline-formula> from 1.58 to 2.79 GHz.
