1. A mobile communication handset, comprising:
- a housing;
a dielectric substrate located within the housing;
at least one passive antenna element disposed on a first portion of the dielectric substrate, the at least one passive element having a base portion;
an active antenna element disposed 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;
a ground structure having a shape that localizes a near field of the antenna elements toward the base portions of the antenna elements; and
a switch disposed between the at least one passive element and the ground structure, the switch controlling electromagnetic coupling therebetween in order to affect the directivity of communication signals coupled to the antenna elements.

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.
