Abstract
A communications device for sending and receiving an information signal. The communications device comprising an element having an opening defined therein for receiving an antenna, the element comprising first conductive material disposed proximate the opening and comprising transmitting and receiving circuits. The antenna comprises: a dielectric tubular member, second conductive material forming an exterior surface of the tubular member with the second conductive material defining a slot therein, a slot length approximately equal to one-half of a guided wavelength and a feed connected to the transmitting and receiving circuits and disposed proximate the slot for establishing currents in the second conductive material.

An antenna for placement in an opening within a first conductive material, the antenna comprising:
- a dielectric tubular member;
- a second conductive material forming an exterior surface of the tubular member;
- the second conductive material defining a slot therein, the slot having a slot length approximately equal to one-half of a guided wavelength and having a slot width, there being no slot present in the tubular member immediately beneath the slot in the second conductive material, wherein a width of the opening defined by the first conductive material is less than a quarter wavelength of the guided wavelength;
- and
- a feed proximate the slot for establishing currents in the second conductive material when the antenna is in a transmitting mode, the currents perpendicular to the slot length.
