[0033] 具体的， 结合图 5所示， 每个辐射器件组 12中， 其中一个连接部 13设有连接件 1 6， 用于与一个馈电桥 20连接， 连接件 16为一凸出销， 另外一个连接部 16设有通 孔 17供传输电缆 30的内导体 31穿过。
[0034] 本实施例中， 连接部 13包括扇环形主体及形成在扇环形主体径向内侧的弧形凸 起， 连接件 16设置在弧形凸起上， 通孔 17位于扇环形主体与弧形凸起连接处。
[0035] 馈电桥 20的两端分别具有馈电桥通孔 21， 如图 7所示， 馈电桥 20的形状为长条 形。 连接件 16与馈电桥 20—端的馈电桥通孔 21间隙配合且焊接在一起， 以将馈 电桥 20与其中一个连接部 13连接在一起。 传输电缆 30包括内导体 31、 环绕在内 导体 31外周的介质层 33、 环绕在介质层外周的外导体 32及环绕在外导体 32外周 的保护层 34， 如图 8所示， 传输电缆 30在接头处的内导体 31、 介质层 33、 外导体 32和保护层 34的一端之间依次形成台阶。 内导体 31穿过通孔 17与馈电桥 20另一 端的馈电桥通孔 21间隙配合且焊接在一起， 以将传输电缆 30与馈电桥 20连接在 一起。 即， 馈电桥 20两端的两个通孔 21分别与连接件 16、 内导体 31间隙配合并 焊接， 从而构成馈电变换器， 使每个辐射器件组 12的电流分布平衡。
[0036] 本实施例中， 还是结合图 5所示， 其中一个辐射器件组 12中， 两个连接部 13分 别具有凹腔 18， 连接件 16和通孔 17分别位于对应的凹腔 18内， 方便每个辐射器 件组 12与馈电桥 20的连接， 结构紧凑。
[0037] 支撑臂 11的外周设有装配槽 113， 如图 6所示， 传输电缆 30容纳于装配槽 113内 ， 且传输电缆 30的外导体 32焊接到装配槽 113， 从而将传输电缆 30固定到支撑臂 11的外侧。
[0038] 连接件 16上固定套设一介质 50， 如图 9所示， 介质 50具有介质通孔 51， 介质 50 通过介质通孔 51与连接件 16间隙配合， 并位于馈电桥 20与对应的连接部 13之间 ， 使馈电桥 20的一端搁置在介质 50上， 有效保证了两者之间的间隙。 在另一种 替换方案中， 也可以是内导体 31上固定套设一介质 50， 介质 50通过介质通孔 51 与内导体 31间隙配合， 并位于馈电桥 20与对应的连接部 13之间， 使馈电桥 20的 另一端搁置在介质 50上， 同样可以保证两者之间的间隙。 介质 50的形状为圆形 、 方形等形状。
以上实施例仅表达了本发明的优选实施方式， 其描述较为具体和详细， 但并不 能因此而理解为对本发明专利范围的限制。 应当指出的是， 对于本领域的普通 技术人员来说， 在不脱离本发明构思的前提下， 还可以做出若干变形和改进， 如对各个实施例中的不同特征进行组合等， 这些都属于本发明的保护范围。
