Problems solved by technology

[0004] While incorporating one or more radios into a base station antenna may provide increased throughput and / or have other advantages, adding a radio to the antenna may increase the size, weight, cost, and complexity of the antenna
Additionally, the radio may operate at high power levels, which also raises concerns about heat generated in the antenna, which can negatively affect the performance of the radio

Embodiment Construction

[0028] According to an embodiment of the present invention, an active antenna is provided having a radio completely enclosed within a housing of the antenna. Such a design simplifies the waterproofing necessary to protect the radio from ingress of moisture and moisture. These active antennas may have a housing with a thermally conductive frame member with integrated therein a heat dissipation structure configured to dissipate heat generated by the radio from the housing . The provision of these thermally conductive frame members can eliminate any need to attach a finned heat sink to the radio. In some embodiments, the active antenna may include one or more vapor chambers or other heat pipes configured to transfer heat generated by the radio to the thermally conductive frame member. A heat dissipation structure integrated into the thermally conductive frame member may include, for example, a plurality of fins.

[0029] The finned thermally conductive frame member included in...

Abstract

The invention relates to a base station antenna with a fully embedded radio and a shell with an integrated heat dissipation structure. An active antenna is provided and includes the shell having a front surface, first and second side surfaces and a rear surface, wherein the front surface includes a radome, and the first and second side surfaces include the respective first and second thermally conductive frame members. The antennas also include at least one radio device mounted entirely within the interior of the shell. Each of the first and second thermally conductive frame members includes aplurality of outwardly extending fins.

Description

technical field [0001] The present invention relates to communication systems, and more particularly to base station antennas with integrated radios. Background technique [0002] Cellular communication systems are now widely deployed. In a typical cellular communication system, a geographic area is divided into a series of areas called "cells," and each cell is served by a base station. A base station may include baseband equipment, radios, and antennas configured to provide two-way radio frequency ("RF") communication to users located throughout a cell. The base station antenna produces an outwardly directed radiation beam ("antenna beam") to serve the entire cell or a portion thereof. Typically, a base station antenna includes one or more phased arrays of radiating elements, which are often referred to as phased array antennas. When the antenna is mounted for use, the radiating elements are typically arranged in one or more vertical columns. The RF signal to be transm...
