Tapered multiband antenna
First Claim
1. A wireless communication device comprising:
- a monopole antenna, wherein the monopole antenna further comprises;
a counterpoise;
a poise comprising;
a conductor having first and second edges, the first edge having a first taper extending from the counterpoise to the second edge, and the second edge having a straight edge or a second taper different from the first taper; and
a substrate, the conductor being deposited on the substrate, wherein the substrate with the conductor deposited thereon is folded; and
a transmission line connected to the poise.

Abstract
Embodiments disclosed herein address the need in the art for a relatively small multi-band antenna. In one aspect, an antenna poise comprises an element, one edge of which is tapered from the connection point of a counterpoise to a second edge of the element. In another aspect, multiple elements are included in the poise, which may include tapered or rectangular poise elements. In yet another aspect, a quarter-ellipse poise is deployed. In yet another aspect, a poise element with an edge formed according to y=1/(m*x) is formed, where m is any number. A poise may be folded, or deposited on a folded substrate. Various other aspects are also presented. These aspects have the benefit of providing desirable frequency response characteristics over a wide frequency range, selectable by design, along with suitability for deployment in a relatively confined space.
