A three-array pole antenna highly suited for use in a communication system, and mounted in a cylindrical cover that may be supported atop a conventional pole of similar diameter. The antenna includes a ground plane structure ( ) with three outwardly facing facets ( ) that are joined together to form a rigid structure. Three antenna feed printed circuit boards ( ) each provide two antenna feeds to an array of antenna patches ( ) that are electromagnetically coupled to the circuit boards. Metal-to-metal connections are limited to radio-frequency (RF) feed connectors to the circuit boards ( ), to minimize intermodulation effects. The entire antenna structure is of low cost and is easy to assemble and install.

Pole antenna with multiple array segments

An indoor cellular band antenna has an outer metal housing having a 90&deg; inner configuration and a radome positioned over the front of the housing. An antenna dipole is mounted in the housing and includes two dipole members. Each dipole member includes a rectangular dipole element extended transmission balun members and a back mounting plate. An antenna cable extends through the top panel of the housing. An outer conductor of the cable is electrically connected to one of the transmission balun member of one dipole member and an inner conductor is electrically connected to the dipole element of the same dipole member. The inner and outer conductors of the cable are mounted to the dipole member by connectors formed from the dipole member.
