First Claim
Patent Images
1. A method of manufacturing a mobile communication handset, comprising:
- disposing at least one passive antenna element on a first portion of a dielectric substrate, the at least one passive element having a base portion;
disposing an active antenna element on a second portion of the dielectric substrate adjacent to the at least one passive antenna element, the active element being coupled to electronic radio communication circuits, the active antenna element having a base portion;
disposing a switch between the at least one passive element and a ground structure, the switch controlling electromagnetic coupling therebetween in order to affect the directivity of communication signals coupled to the antenna elements, the ground structure having a shape that localizes a near field of the antenna elements toward the base portions of the antenna elements; and
disposing the dielectric substrate within a housing.

Abstract
A mobile communication handset includes at least one passive antenna element and an active antenna element adjacent to the passive antenna elements protruding from a housing. The active element is coupled to electronic radio communication circuits and the passive antenna elements are coupled to circuit elements that affect the directivity of communication signals coupled to the antenna elements.
