| Zusammenfassung: | 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 (26) with three outwardly facing facets (28) that are joined together to form a rigid structure. Three antenna feed printed circuit boards (14) each provide two antenna feeds to an array of antenna patches (16) that are electromagnetically coupled to the circuit boards. Metal-to-metal connections are limited to radio-frequency (RF) feed connectors to the circuit boards (24), to minimize intermodulation effects. The entire antenna structure is of low cost and is easy to assemble and install. |
