本发明的较佳实施方式
下文中将结合附图对本发明的实施例进行详细说明。 需要说明的是， 在 不冲突的情况下， 本申请中的实施例及实施例中的特征可以相互任意组合。 实施例一：
本实施例提供的天线包括天线本体以及设置于天线本体上的至少两个馈 点； 本实施例中的天线本体包括天线辐射体， 各馈点与天线本体实现对应频 段的信号的收和 /或发。 本实施例中天线的类型可根据应用场景选定， 例如可 为但并不仅限于 PIFA天线、 IFA天线或 Monopole天线。 对应的， 本实施例 天线本体。 同时， 本实施例中在天线本体上设置馈点的个数以及设置的位置、 方式等都可根据应用场景选择设置， 例如可在天线本体上设置两个、 三个或 四个等馈点。 馈点设置的位置则只要能满足相应的辐射频段的要求即可。 同 时， 对于不同类型的天线， 馈点的设置方式也都可根据具体情况选择设置， 例如， 对于 PIFA、 IFA设置时则需要短路点设计， 而对于 Monopole天线则 不需要。 下面结合图 2所示的天线结构进行示例性说明。
请参见图 2所示， 图 2所示则为本实施例中一种天线的结构示意图， 包 括天线本体 10, 以及设置在天线本体 10上的 4个馈点， 分别为第一馈点 11 , 第二馈点 12, 第三馈点 13以及第四馈点 14。
实施例二：
请参见图 3所示， 该图所示为一种天线装置， 该天线装置包括实施例一 中所示的天线 1 , 还包括射频电路模块 2, 射频电路模块 2包括频段射频信号 处理模块 21和频段切换子模块 22, 频段切换子模块 22设置为选择频段射频 信号处理模块 21对不同频段的射频信号进行处理的功能，即选择不同的射频 频段， 在不同频段之间切换； 天线本体上的各馈点则分别与频段切换子模块 22连接， 以配合天线本体实现对应频段的信号的收和 /或发。
在本实施例中， 天线本体上设置的馈点的个数可以与射频电路模块 2支 持的频段数相同， 也可以不同， 例如， 对于射频电路模块 2支持的频段是相 邻频段时， 则可设置各相邻频段共用一个馈点实现， 当然也可分别对应一个 馈点实现； 对于射频电路模块 2支持的频段不是相邻频段时， 则可直接设置 每个馈点对应一个频段。
当直接利用天线本体调试得到的频段不能满足要求时， 还可通过设置如 图 4所示的匹配电路模块 3 , 至少一个馈点通过该匹配电路模块 3与频段切 换子模块 21连接； 匹配电路模块 3则设置为调节天线 1的各路信号的阻抗匹 配。 本实施例中的匹配电路的类型也可根据应用场景选择设置。
本实施例中， 匹配电路模块 3包括匹配电路切换子模块 32和与天线本体 上设置的馈点个数相同的多个匹配电路子模块 31 (图中仅示出一个） ， 频段 切换子模块 32与匹配电路子模块 31连接， 设置为将各馈点与对应的匹配电 路子模块 31连通， 匹配电路子模块 31的类型可根据具体情况选用， 例如可 为 T型匹配电路、 L型匹配电路、 双 L型匹配电路等等。 当各馈点与匹配电 路子模块 31——对应连接时， 每个馈点可对应实现一个特定频段， 此时匹配 电路切换子模块 32与频段切换子模块 22的工作时序一致， 可同时切换射频 频段以及对饮的匹配电路子模块。 当共用一个馈点实现多个相邻频段时， 该 馈点则可选择与其中一个匹配电路切换子模块 31连接，也可选择与多个匹配 电路切换子模块 31连接， 此时匹配电路切换子模块 32与频段切换子模块 22 的工作时序则可不一致。 请参见图 5所示， 本实施例中的天线装置还包括切 换控制模块 4, 该切换控制模块 4则设置为控制频段切换子模块 22和匹配电 路切换子模 32按照上述方式进行切换，本实施例中切换控制模块 4可釆用底 层驱动控制。
本实施例中的天线以及天线装置可应用于各种终端中， 例如可应用于手 机、 PAD等各种移动终端中； 当然也可用于需要设置天线的非移动终端中。
可见， 本发明实施例中的天线包括的天线本体上设置的多个馈点中， 每 个馈点可与天线本体实现对应频段的信号的收和 /或发， 可避免现有传统天线 设计需要覆盖多个频段时需增加相应的电路和天线空间的问题， 减少多频段 天线占用的空间及面积的问题， 更利于超薄移动终端尺寸的设计。
以上内容是结合具体的实施方式对本发明所作的进一步详细说明， 不能 认定本发明的具体实施只局限于这些说明。 对于本发明所属技术领域的普通 技术人员来说， 在不脱离本发明构思的前提下， 还可以做出若干简单推演或 替换， 都应当视为属于本发明的保护范围。
工业实用性
本发明实施例可以避免现有传统天线设计需要覆盖多个频段时需增加相 应的电路和天线空间的问题， 减少多频段天线占用的空间及面积的问题， 更 利于超薄移动终端尺寸的设计。
