Abstract

An antenna (10) includes a substrate (12) including a ground plane (26) and a dielectric layer (24) adjacent thereto and at least one antenna unit (13) carried by the substrate (12). The at least one antenna unit (13) may include a plurality of adjacent antenna elements (14, 16, 18 and 20) arranged in spaced apart relation from one another about a central feed position (22) on the dielectric layer (24) opposite the ground plane (26). The at least one antenna unit (13) may also include an antenna feed structure (30) including a respective coaxial feed line (32) for each antenna element (14, 16, 18 and 20) and a feed line organizer body (60) having passageways (61) therein for receiving respective coaxial feed lines (32).

Description

[0001] related application [0002] This invention is a continuation, in part, of US Application No. 09 / 702,712, filed October 31,2000. field of invention [0003] The invention relates to the communication field, in particular to a phase array antenna. Background technique [0004] Existing microwave antennas include a variety of configurations for various applications such as satellite reception, long-range broadcasting, or military communications. Printed circuit antennas generally provide the desired characteristics of low cost, light weight, small cross-section, and mass production, wherein a planar conductive element is separated from a single substantially continuous ground element by a thin dielectric sheet of uniform thickness. Antennas are designed as arrays and are used in communication systems such as identification friend or foe (IFF) systems, personal communication services (PCS) systems, satellite communication systems, and aerospace systems that require ante...
