Vivaldi cloverleaf antenna
First Claim
1. An antenna comprising a plurality of flared notch antennas disposed immediately adjacent each other, each flared notch antenna having a direction of maximum gain which is directed in a different direction for each flared notch antenna, each flared notch antenna being defined by a pair of confronting elements, each said element being associated with two different ones of said plurality of flared notch antennas and each said element having a gap therein, said gap having a length which is approximately equal to a quarter wave length of a radio frequency signal to be received and/or transmitted by the antenna.

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.
