技术领域
本公开涉及无线通信技术领域，具体涉及一种金属边框天线装置和移动终端。
背景技术
目前金属边框天线被广泛地应用于移动终端中，现有的金属边框天线方案利用金属开缝，通过断缝把天线隔成多个部分，分别实现不同的天线频段。但是，一旦断缝位置固定，则难以通过改变断缝的位置调节频段。并且自5G商用以来，天线所需覆盖的频段愈来愈宽，加之全面屏手机的普及使天线的布置环境受到较大的限制，进而对低频带宽影响较大，然而现有的金属边框天线如需覆盖全频段，则低频带宽需要从600MHz覆盖至960MHz，所要切换的频段也比较多，如果使用多个调谐器或开关，则会增加硬件成本。因此如何以更低的成本灵活切换天线频率以实现更宽的频段覆盖范围，是目前金属边框天线面临的技术难题。
