Abstract
A broadband spiral antenna wherein the outermost spirals for lower frequency operation are formed in the shape of a four lobed cloverleaf so that the low frequency operation can be provided in a relatively limited space leaving room for four other spiral antennas between the lobes so that two orthogonal arrays of three antennas each with the center cloverleaf antenna being common to both arrays can be used to determine the directional characteristics of a radiating source being detected.
