本發明申請案涉及一種基於適用於多頻段的天線結構及包括該天線結構的無線通訊裝置。
隨著現代通訊技術的發展，移動裝置成為人們生活中不可或缺的一部分，通訊系統對通訊效率要求越來越高。第五代移動通訊技術5G可實現速度更快及網路容量更大的通訊需求，而為了實現這個需求使用多天線設計MIMO(Multiple-Input Multiple-Output，多入多出)架構是常用的設計。但是在移動裝置的有限空間內同時放入適用於2G、3G、4G天線和5GMIMO等多個天線的架構對天線設計與移動裝置結構設計是重大的課題。
有鑑於此，有必要提供一種適用於多頻段的天線結構及包括所述天線結構的無線通訊裝置。

可以理解，所述第一天線12及所述第二天線14的多個5G天線141-148均具有接地端，例如通過電路板或所述無線通訊裝置200的殼體接地。
當所述處理器18分別向所述第一天線12及所述第二天線14的多個5G天線141-148饋入電流，電流沿所述第一天線12及所述第二天線14的多個5G天線141-148流動，以激發一第一模態及一第二模態以產生第一頻段及第二頻段的輻射訊號。本實施例中，所述第一模態包括5G模態，所述第一頻段包括5G頻段5000-6000MHz；所述第二模態包括低頻模態、中頻模態及高頻模態，所述第二頻段包括低頻頻段699-960MHz、中頻頻段1710-2170MHz及高頻頻段2300-2690MHz，也即所述第二頻段的輻射訊號包括了2G、3G、4G頻段。
