Abstract

A mobile data terminal external antenna is disclosed for use with a battery powered data processing terminal which includes a radio frequency communication device, such as a cellular telephone transceiver.
Multiple antenna elements are mounted within a D-shaped flexible tubular member having a very low dielectric constant which is then affixed to the external surface of the data processing terminal, utilizing an adhesive on the flat surface thereof. The flexible tubular member is preferably mounted along at least two edges of the data processing terminal display module such that spatial or polarization diversity for the multiple antenna elements may be provided. A coaxial connector is utilized to couple the multiple antenna elements to a radio frequency communication device within the data processing terminal. In this matter, an external antenna may be added to a battery powered data processing terminal in a manner which will protect the antenna without interfering with radio frequency transmission or reception while simultaneously providing additional protection for the data processing terminal.
