Classification: CPC H | IPC H

Claim 17:
18. An antenna, comprising:
an antenna ground plane comprising an antenna element, the antenna element being fed at a first feeding point from N different sides, where N is an integer greater than 1;
an unequal 1:N power divider connected to the antenna ground plane as a feeding network to excite the fist feeding point;
a power divider bottom part of the power divider;
a bottom substrate disposed on the power divider bottom part, the antenna ground plane being disposed on the bottom substrate;
a top substrate disposed on the antenna ground plane;
a power divider top part of the power divider disposed on the top substrate; and
a power divider via connecting the power divider bottom part to the power divider top part at a first location and going through the bottom substrate, the antenna ground plane, and the top substrate,
the first location being spaced apart from the first feeding point,
the bottom substrate being in direct physical contact with the power divider bottom part,
the antenna ground plane being in direct physical contact with the bottom substrate,
the top substrate being in direct physical contact with the antenna ground plane,
the power divider top part being in direct physical contact with the top substrate,
the antenna having a bandwidth that is at least 75% larger than a bandwidth of a single-side-fed antenna with a same footprint as the antenna,
each side of the N sides exciting a same mode of operation of the antenna at its own respective impedance, and
the antenna being configured to exhibit consistent radiation performance across an entire operational bandwidth of the antenna.
