Abstract
A diversity antenna module includes a diversity antenna and preferably has outer dimensions no larger than a SIM card. The diversity antenna module mates with a shell housing communications electronics for a wireless communications device, such as communications electronics adapted for PDC operation. The diversity antenna module, when mated to the shell, provides the communications electronics within the shell with an alternative antenna, as is required by the PDC specifications. The same shell, or another shell of the same mechanical dimensions, may alternatively house a different set of communications electronics, such as some adapted for GSM operation. A traditional SIM module may be mated to this second shell to provide alternative communications functionality. Thus, the diversity antenna module allows for a single mechanical design of the shell to be used to house alternative communications electronics and mate with the corresponding modules to provide wireless communications functionality under differing standards, thereby reducing the number of mechanical packaging designs that must be developed.
