Communication device using antenna having an offset

摘要

A radio communication device (100) includes an offset antenna (104) and a housing (101). The offset antenna (104) includes an offset portion (108) and radiating portion (116). The antenna (104) is coupled to the radio housing (101) through a pivot mechanism (106) so that the antenna could rotate from a stowed position (114) to a deployed position (112). In the deploy position (112), the antenna is away from the user, a distance equal to the sum of the width (110) and the offset portion (108). This separation of the antenna from the body provides for significant improvement in the antenna performance.
