ABSTRACT:
An antenna unit having an antenna casing secured to a signal transmitting and receiving circuit. An antenna cover is slidably coupled to the antenna casing. An antenna element is provided inside the antenna cover. A coiled spring portion connects the antenna element to the signal transmitting and receiving circuit. The antenna element and the coiled spring portion are provided as one integral coil of wire. A clip is secured to the antenna cover and is engaged with a border between the antenna element and the coiled spring portion so as to keep the antenna element stationary relative to the antenna cover, thereby keeping the electrical characteristics of the antenna element constant, even when the antenna cover is slid relative to the antenna casing. The antenna element remains connected to the signal transmitting and receiving circuit at all times.
