Abstract

Systems and methods are disclosed for insert-molding various electronic and mechanical parts as part of a housing of an electrical device. The insert molded components can comprise antennas, flex members and circuits, electronic, mechanical, and interface units that have been insert molded as part of a plastic housing that contains the electrical device.

Claims

1. A housing compartment comprising:

a body for containing a unit that comprises at least one of a transmitter and a receiver; and

an antenna of the unit insert-molded as part of the body, the antenna supported by a support core to conform the antenna to an intended shape.

2. The housing compartment of claim 1, the antenna at least one of transmits and receives signals associated with at least one of a Local Area Network, a Wide Area Network and a Personal Area Network.

3. The housing compartment of claim 1, the antenna comprising a dual band antenna.

4. The housing compartment of claim 1, the antenna comprising a plurality of metal strips formed on a dielectric member.

5. The housing compartment according to claim 4, the plurality of metal strips formed by at least one of an etching and a printing on the dielectric member.

6. The housing compartment according to claim 1, the antenna insert-molded entirely within the body.

7. The housing compartment according to claim 1, further comprising a metal conductor formed into a shape having at least one of a curved coil and an elongated part, the metal conductor at least one of transmits and receives at frequencies of 900 MHz and 1800 MHz.

8. The housing compartment according to claim 1, the antenna at least one of transmits and receives at frequencies of 2.4 Hz and 5.2 GHz.

9. The housing compartment according to claim 1, the body further comprises a recess shaped at the antenna, the antenna resides within the recess.

10. The housing compartment according to claim 1, the antenna is electromagnetically coupled to at least one of the transmitter and the receiver.

11. The housing compartment according to claim 1, the body fabricated from at least one of a thermoset plastic and a thermoformed plastic material.
