IMPROVED DIVERSITY ANTENNA ASSEMBLY FOR WIRELESS COMMUNICATION EQUIPMENT

摘要

An antenna assembly (AA), forwireless communication equipment, comprises i) an antenna structure comprising at least a loop type antenna (LA) arranged to deliver a first current when it is used in a balanced mode and/or a second current when it is used in an unbalanced mode with respect to a ground plane (GP) from received radio signals, and ii) current extraction means (A1, A2) coupled to the antenna structure (LA) and arranged to be placed in at least a first state in which they deliver the first or second current and a second state in which they simultaneously deliver the first and second currents either separately or mixed together.
