Abstract
A cap assembly attachable to a main housing of a handheld device. The cap assembly includes a cap body at least partially defining one or more cavities therein, and one or more WAN antennas receivable in the cavity. In addition, the cap assembly includes an electromagnetic shield receivable in the cavity for providing each WAN antenna with a predetermined electromagnetic environment in which the impedances of the WAN antenna and the electromagnetic shield are substantially matched.
Claims20
A cap assembly attachable to a main housing of a handheld device, the cap assembly comprising:
- a cap body at least partially defining at least one cavity therein;
- at least one Wide Area Network (WAN) antenna receivable in said at least one cavity;
- and
- an electromagnetic shield receivable in said at least one cavity for providing said at least one WAN antenna with a predetermined electromagnetic environment in which the impedances of said at least one WAN antenna and the electromagnetic shield are matched.
A handheld device comprising:
- a main housing;
- a cap assembly attachable to the main housing, the cap assembly comprising:
- a body at least partially defining at least one cavity therein;
- at least one Wide Area Network (WAN) antenna receivable in said at least one cavity;
- and
- an electromagnetic shield receivable in said at least one cavity for providing said at least one WAN antenna with a predetermined electromagnetic environment in which the impedances of said at least one WAN antenna and the electromagnetic shield are matched.
An electromagnetic shield for use in a handheld device comprising at least one Wide Area Network (WAN) antenna and at least one scanner, the electromagnetic shield comprising:
- a conductive material electrically connected to an electrical ground in the handheld device, the conductive material being positioned between said at least one scanner and said at least one WAN antenna;
- and
- the conductive material and said at least one WAN antenna having matched impedances for providing said at least one WAN antenna with a predetermined electromagnetic environment relative to said at least one scanner.
