摘要： A crossed dipole antenna element comprising first and second dipoles, each dipole having a pair of arms, each arm having a first portion extending from a central axis and a second portion extending out of a plane including the first portion and the central axis. In certain embodiments the second portions of the arms of the first dipole extend in a first rotational direction and the second portions of the arms of the second dipole extend in a second rotational direction. This improves the isolation performance of the antenna. In certain embodiments the second portion of each arm branches out at an intermediate position along the length of the arm. This improves the bandwidth performance of the antenna.

摘要： A low sidelobe beam forming method and dual-beam antenna schematic are disclosed, which may preferably be used for 3-sector and 6-sector cellular communication system. Complete antenna combines 2-, 3- or -4 columns dual-beam sub-arrays (modules) with improved beam-forming network (BFN). The modules may be used as part of an array, or as an independent 2-beam antenna. By integrating different types of modules to form a complete array, the present invention provides an improved dual-beam antenna with improved azimuth sidelobe suppression in a wide frequency band of operation, with improved coverage of a desired cellular sector and with less interference being created with other cells. Advantageously, a better cell efficiency is realized with up to 95% of the radiated power being directed in a desired cellular sector.

摘要： A dual polarized three-sector base station antenna with variable beam tilt in each sector. The invention advantageously provides a variable phase shifter with very small lateral dimensions which significantly reduces the diameter of a three-sector antenna. The feed network is located on both sides of the antenna ground plane, and the combination of the cable, microstrip and airstrip lines further reduces the lateral size of the antenna. Metal rings on the radome and double-bended ground plane are providing antenna with better cross-polarization and port-to-port isolation.

摘要： A dual band, dual pole, variable downtilt, 90 degree azimuth beamwidth antenna (10). The antenna includes dipole elements (12, 14) forming both a PCS band and a cellular band antenna. The PCS band antenna has two sections disposed each side of the cellular band antenna, the elements of each being positioned 90° with respect to the other. A microstrip feed network formed upon a common PC board (18) feeds the respective dipole elements, and has serpentine portions with a corresponding dielectric member slideable thereover to establish the phase of the associated dipole antennas and achieve a linear downtilt of the respective antenna array. A slide rod adjustment assembly (100) provides unitary movement of the dielectric members between two different slide rods. These dielectric members are secured with adhesive to the respective slide rods to achieve good dielectric control and no use of hardware. The radiating dipole elements are capacitively coupled to each microstrip, and are also capacitively associated reflector element. One arm of the reflector element is offset at least 45 degrees with respect to the other arm to improve cross polarization.
