ABSTRACT:
A wireless communication device has a housing, an antenna, and a preferably flexible substrate. The housing has first and opposed second major surfaces. The antenna is fixed to the flexible substrate, and is disposed within the housing. The antenna has first and second antenna portions. The first antenna portion is disposed nearer to the first major surface than to the second, and the second antenna portion is disposed nearer to the second major surface than to the first. Preferably, the antenna radiates in two different frequency bands, and radiation in the higher band occurs entirely within the second antenna portion when the first major surface is a surface intended to mate with or lie adjacent to a user's head when the device is in use, so that the first antenna portion shields higher radiation that is received at or transmitted from the second antenna portion.
