Embodiment Construction

[0031]According to an embodiment of the present invention, there is provided a base station antenna having a controller designed to sequentially adjust two RET actuators of the antenna by actuating two or more different RET actuators in response to a single control signal. Declining on different vertical arrays. This scheme allows a common base station antenna design to be used both for (1) customers who want to control each RET actuator independently and (2) who want to control two or more RET actuators using a single control signal customer of. This approach can eliminate the need to design and manufacture multiple versions of the antenna to accommodate customers desiring different granular control of the RET actuator. Furthermore, the ability to actuate multiple RET actuators in response to a single control signal can be implemented, for example, only in firmware, so that the only difference between two antennas with different capabilities can be the RET configuration data...

Abstract

A method of operating a base station antenna includes receiving a first control signal at the base station antenna, activating a first actuator to move a first mechanical linkage in response to the first control signal, and activating a second actuator in response to the first control signal to move the second mechanical linkage. According to these methods, the base station antenna may be configured to control the first actuator and the second actuator both independently and jointly.

Description

[0001] Cross References to Related Applications [0002] This application claims priority under 35 U.S.C. §119 to U.S. Provisional Patent Application Serial No. 62 / 478,632, filed March 30, 2017, which is hereby incorporated by reference in its entirety as if fully set forth. technical field [0003] The present invention relates to communication systems, and in particular, to base station antennas with long-range electronic downtilt capability and methods of operating such antennas. Background technique [0004] Base station antennas of wireless communication systems are used to transmit radio frequency ("RF") signals to and receive RF signals from fixed and mobile users of cellular communication service. Base station antennas are directional devices that can focus RF energy sent in and received from certain directions. The "gain" of a base station antenna in a given direction is a measure of the antenna's ability to focus RF energy in that particular direction. The "radia...
