2、如图8、图9所示，本发明天线2.6GHz和3.4GHz频段的左、右圆极化半功率波束宽度分别为58.6度和36.7度；
3、如图7所示，有效工作(轴比<3dB、电压驻波比<2.0、增益>5dBic)频率为2.59GHz-2.61GHz和3.38GHz-3.42GHz，带宽分别为0.03GHz和0.04GHz；
4、在2.59GHz-2.61GHz和3.38GHz-3.42GHz的频段范围内，能够实现良好的左、右圆极化性能覆盖；
5、在2.59GHz-2.61GHz和3.38GHz-3.42GHz的频段范围内，具有良好阻抗匹配；
6、如图7所示，在2.59GHz-2.61GHz的频段范围内，能够实现最大6.78dBic的左、右圆极化增益；
7、如图7所示，在3.38GHz-3.42GHz的频段范围内，能够实现最大5.29dBic的左、右圆极化增益；
8、如图8、图9所示，此天线平均波束下倾角为19度；
9、本发明实现了不对称贴片结构的天线化；
10、天线采用的铜或者铝作为接地板200，单层介质层板100及3D“L”形探针300，强化了天线辐射，实现多频段应用，制作工作简单、材料极易获取、天线成本低廉；
11、发明天线具有“家”字艺术外形，可有效对天线实现“隐身”，尤其适用于会厅、展馆等公共场所，同时可避免电磁敏感类人群对于天线的恐惧心理；
12、发明天线具有国家汉字外形，通过推广安装于我国驻外使领馆、国外中资企业、我国涉外酒店等场所，可对中国文化的传播起到积极的推动作用。
本发明“家”字形圆极化贴片天线，提供了一种汉字外形天线，以汉字“家”作为天线的几何形状，并实现WiMAX(2.6G)无线宽带和3.4GHz的5G无线网络的双频要求，兼容性强；本发明改进了现有技术中的“L”形探针，采用3D“L”形的探针，以介质层板下表面矩形金属板B102为辅助进行馈电，该方法较之原来的“L”形探针增加了并联电容，增强了探针与贴片天线之间的电容量， 改善了反射系数，更容易和贴片天线的阻抗匹配，使得“家”字完全不具备对称结构的汉字形贴片实现宽带效果。
本发明的天线为汉字“家”的外形几何结构，体积小，采用单层介质层板及低成本铝板或铜板作为接地板，“家”字形天线主体雕刻在介质层板的金属层上，结构简单、成本低廉。
本发明的“家”字形天线，以汉字中的“家”字为原形，充分利用其笔画结构，在满足天线性能要求的前提下，实现天线的艺术化，将艺术与科技进行结合，将艺术融入天线设计，拓展了天线的设计理念；本发明在实现天线“隐身”功能的同时，进一步传播了中华精神、中国汉字文化。
以上所述为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书以及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
