Abstract

A continuous housing (100) and integral antenna (102) and method (300) of forming a housing (100) and integral antenna (102), including: forming (305) an extrusion housing with a side opening defining a pocket configured to receive electrical components; removing (310) material of the extrusion housing in proximity to a wall portion of the extrusion housing; and forming (315) a desired antenna construction integral to the extrusion housing. Advantageously, the continuous housing (100) can form a wireless communication device, which is particularly adapted for mass production. This arrangement is adapted to allow a customer to design the look and feel of an electronic device.

Claims
