First Claim
Patent Images
1. An antenna comprising:
- a foam core;
a flex circuit wrapped around the foam core, the flex circuit having a flexible substrate that includes a first portion, a second portion substantially parallel with the first portion, and a third portion substantially perpendicular to the first portion connecting the first and second portions, the flex circuit also including a circuit pattern to transmit and receive electromagnetic signals, the circuit pattern disposed on the first portion of the flexible substrate;
a ground connector extending from a perimeter of the circuit pattern; and
a feed connector extending from the perimeter of the circuit pattern and more distal to a center of the circuit pattern than the ground connector.

Abstract
Lightweight, small antennas are described that have decreased material and fabrication/processing cost. The antennas may be used in consumer electronics products such as cellular phones, laptops and PDA'"'"'s. Some of the antennas and fabrication techniques also provide lower part count and increased reliability. All antennas are fabricated with standard materials currently available in high volume production.
