Multi-frequency antenna module for an electronic apparatus
First Claim
1. A multi-frequency antenna module for an electronic apparatus, the electronic apparatus including a housing, and a circuit board disposed in the housing and provided with first, second and third electrical contacts thereon, said multi-frequency antenna module comprising:
- a dielectric substrate adapted to be mounted in the housing and having a mounting surface;
a first radiating element disposed on said mounting surface of said substrate and including a serpentine first transmission line conductor that has a first free end, and a first contacting end opposite to said first free end and adapted to contact electrically the first electrical contact on the circuit board when said substrate is mounted in the housing, said first transmission line conductor having a plurality of parallel first transmission line segments, and a plurality of parallel second transmission line segments, each of which is transverse to said first transmission line segments and interconnects a respective adjacent pair of said first transmission line segments, said first radiating element further including at least one conducting line that is disposed parallel to said second transmission line segments and that interconnects an adjacent pair of said first transmission line segments;
a second radiating element disposed on said mounting surface of said substrate, spaced apart from said first radiating element, and including a second transmission line conductor that has a second free end, and a second contacting end adapted to contact electrically the second electrical contact on the circuit board when said substrate is mounted in the housing; and
a grounding line conductor disposed on said mounting surface of said substrate, coupled electrically to said first radiating element, and adapted to contact electrically the third electrical contact on the circuit board when said substrate is mounted in the housing.

Abstract
A multi-frequency antenna module includes first and second radiating elements disposed on a substrate and spaced apart from each other. A serpentine first transmission line conductor of the first radiating element and a second transmission line conductor of the second radiating element contact electrically and respectively first and second electrical contacts on a circuit board in an electronic apparatus when the substrate is mounted in a housing of the electronic apparatus. The first radiating element further includes at least one conducting line that is disposed parallel to second transmission line segments and that interconnects an adjacent pair of parallel first transmission line segments. A grounding line conductor is disposed on the substrate, is coupled electrically to the first radiating element, and contacts electrically a third electrical contact on the circuit board when the substrate is mounted in the housing.
