Abstract
An improved antenna system for transmitting and receiving electromagnetic signals comprising a mounting plate having a length and a longitudinal axis along the length. A plurality of staggered dipole radiating elements project outwardly from a surface of the mounting plate. Each of the radiating elements includes a balanced orthogonal pair of dipoles aligned at first and second predetermined angles with respect to the longitudinal axis, forming crossed dipole pairs. The mounting plate is attached to a longitudinally extending chassis. An unbalanced feed network is connected to the radiating elements. The feed network extends along the mounting plate and is spaced from the mounting plate by a plurality of clips. The feed network is disposed between the chassis and the mounting plate. A plurality of microstrip hooks are provided, each of the microstrip hooks being positioned adjacent to, and spaced from, each of the dipoles by one of the clips.
