Abstract

A radiotelephone housing includes an antenna enclosure extending outwardly therefrom having an internal passage configured to receive an internally-mounted antenna therewithin. The antenna enclosure is integrally formed with the radiotelephone housing such that an antenna secured therewithin is protected from damage caused by impact forces to the radiotelephone. An electronic substrate hosting a transceiver preferably includes an antenna extending from an end portion thereof that is configured to be inserted within the antenna enclosure. A coaxial connector or other electro-mechanical connecting device is not required for connecting the antenna to the transceiver.
