Abstract
A directional antenna is provided that utilizes an existing light source or simple reflector having a beam directing reflective surface and a transparent cover for transmitting and receiving electromagnetic radio waves. In an aspect, an information signal is impressed across a conductive material formed to a transparent cover and the reflective surface directs electromagnetic radio waves in a predetermined direction. Beam pattern, gain, polarization and wavelength can be selected through the design and positioning of the conductive material from the reflective surface for providing an effective resonant antenna. The radiated information signal may be used to detect an object or communicate with a receiver. The light source or reflector can be attached to a fixed structure or to a mobile vehicle. In the case of a mobile vehicle, the antenna is fully concealed. In an aspect, material costs, manufacturing costs and assembly costs are reduced as compared to presently available antennas.
