Antenna for portable electronic device wireless communications adapter
First Claim
1. An antenna associated with a wireless communications adapter for a portable electronic device, wherein the antenna is formed partly using a conductive structure in the portable electronic device that serves as a parasitic antenna element, the antenna comprising:
- a discrete surface mount antenna structure in the wireless communication adapter that forms a resonating element for the antenna;
a printed circuit board ground plane in the wireless communications adapter that forms an antenna ground for the antenna, wherein the discrete surface mount antenna structure is mounted to the printed circuit board; and
a resistor that electrically connects the ground plane and the conductive structure in the portable electronic device that serves as the parasitic antenna element.

Abstract
Antennas are provided for portable electronic devices. A portable electronic device may have a port that receives a wireless communications adapter. The adapter may be used to provide wireless functionality for the portable electronic device. The adapter may contain a chip antenna that serves as an antenna resonating element. A printed circuit board within the adapter may contain conductor that has been patterned to form a ground plane for the antenna. The portable electronic device may have a conductive structure such as a housing portion. The conductive structure of the portable electronic device serves as a parasitic antenna element that improves antenna efficiency. The portable electronic device may be a handheld electronic device with music player functionality that communicates with a compact portable wireless device in a piece of sports equipment.
