摘要： An antenna array comprises a reflector and a plurality of columns of unit cells disposed on a first side of the reflector, each of the unit cells having a plurality of radiating elements. Disposed on a second side of the reflector is a plurality of phase shifter boards that are mounted perpendicular to the reflector. Each of the phase shifter boards has a plurality of traces, each of which are coupled directly to corresponding unit cells. An advantage of the disclosed antenna array is that it requires no cables for connection between the phase shifter boards and the radiating elements.

摘要： Disclosed is a high frequency radiator for an antenna. The high frequency radiator is formed of two interlocking PCB stems on which a radiator plate is mounted. Disposed on each of the interlocking PCB stems are two combinations of a feeder metallic trace and an opposing metallic trace, disposed on opposite sides of the PCB stem and electrically coupled together by at least one via formed in the PCB stem and a solder point within the via. This configuration of high frequency radiator is considerably cheaper to manufacture compared to conventional designs and is less susceptible to impedance matching problems resulting from inconsistent solder joint dimensions.

摘要： Disclosed is a multiband antenna that has a plurality of first unit cells and second unit cells. Each first unit cell has two high band radiator clusters and two low band radiators disposed approximately in the center of each of the high band radiator clusters. Each second unit cell has two high band radiator clusters and one low band radiator that is disposed between the two high band radiator clusters. The first unit cell is designed for a superior low band gain pattern, and the second unit cell is designed for a superior high band gain pattern. By selectively arranging the first and second unit cells in a specific heterogeneous pattern, the characteristics of the two unit cells may advantageously and constructively combine to form a high performance antenna gain pattern that is consistent across the low band and high band.
