US 11,909,090 B2 · Antenna system

Abstract

A multi-band antenna has a feed point, a grounding location, a first portion for low band operation, a second portion for low band operation, and one or more portions for high band operation. The ground reference of the feed point for the multi-band antenna is connected to a separate object that may provide a base for the multi-band antenna. The feed point of the multi-band antenna may be spaced above the base and have a space between the feed point and a location for the ground point. The low band portion has multiple resonances that are often odd multiples of the lowest resonant response. The portions that resonant most dominantly in the high band often have multiple resonances that are even multiples of the lowest high band resonance. The multi-band antenna has resonances spaced closely enough to appear to be a wide band antenna above the fundamental high band resonance.

Dependent claims

A multi-band antenna, comprising:

a feeding portion;
a grounding portion;
an upright low band radiation portion;
a second low band radiation portion;
