Abstract

Indoor/outdoor broadband wireless combined radio/antennas configured to include an integrated adjustable mount allowing mounting to a pole or stand and adjustment of the angle of the device (e.g., the altitude) by a lockable ball joint. The device may include a compact array antenna having a high gain configured to operate in, for example, the 5.15 to 5.85 GHz band and/or the 2.40-2.48 GHz band. The antenna emitters may be arranged in a separate plane from a plane containing the antenna feed connecting the emitting elements and also from a ground plane. The antenna array may be contained within a protective weatherproof housing along with the radio control circuitry. The antenna may be manufactured by a simple stamping/forming process. The apparatuses may be configured for low impedance mismatch and may have a high gain relative to a very small and compact overall shape.
