Abstract

An antenna for receiving and/or transmitting a radio frequency wave. The antenna includes a plurality of flared notch antennas disposed adjacent to each other and arranged such that their directions of maximum gain point in different directions, each of the flared notch antennas being associated with a pair of radio frequency radiating elements and wherein each radio frequency radiating element serves as a radio frequency radiating element for two different flared notch antennas and has a gap therein having a length equal to approximately one quarter wavelength of the radio frequency wave.
