Embodiment Construction

[0023] The present invention fulfills the above-mentioned need by a RET antenna with a multi-device control unit that can be inserted into and removed from the socket of the antenna. The multi-device control unit works with one or more modular switching units, typically located within the antenna housing. The MCU works with the motors and position sensors located within the antenna to enable a single controller located in the MCU to control multiple embedded electro-mechanical actuators such as phase shifter controlled motors. This enables multiple motors to share a common control system located in a multi-device control unit, which greatly reduces the number of electronic components required for a multi-beam RET antenna.

[0024] A multi-device control unit typically includes one or more lightning protection circuits, communication circuits, motor controllers, power control circuits, and motor position sensing circuits within a small housing, usually within an antenna housing...

Abstract

RET antenna with a modular switching unit and a multi-device control unit con figured to be inserted into and removed from a receptacle in the antenna. The multi- device control unit works together with motors and position sensors located inside the antenna to allow a single controller located in the multi-device control unit to control multiple embedded electro-mechanical actuators, such as phase shifter control motors. The multi-device control unit includes lightning protection circuits, communications circuits, a motor controller, power control circuits and a motor position sensing circuit inside a small housing. These components are shared between all motors inside the antenna through the modular switching unit, which allows a single set of components within the multi-device control unit to replace redundant components deployed in prior RET antennas.

Description

[0001] Reference to priority application [0002] This application claims priority to commonly owned US Provisional Patent Application No. 60 / 027,687, the contents of which are incorporated herein by reference. technical field [0003] This invention relates to the field of cell phone or mobile phone base station antennas, and more particularly, to a remote electric tilt (RET) base station antenna with a removable multi-device control unit that can be switched to Remote control of more than one electro-mechanical actuator in the machine. Background technique [0004] Antennas with variable electric tilt (VET) functionality are known in the art. These antennas, often used in cellular networks, enable network operators to electrically tilt the antenna's elevation beam pointing direction by manually rotating a knob or translating a shaft located on the outside of the antenna. The knob or shaft is connected to a phase shifter within the antenna that converts mechanical rotatio...
