摘要

将介绍地面天线的概念及其在智能手机和平板电脑等手持通信设备上的应用前景。地面天线是通过添加非常小尺寸的辐射元件与设备地平面结合形成的，以实现用于多频段/宽带操作的高效辐射器。讨论了地面天线设计的最新进展。将讨论可适应环境变化或可调谐以覆盖不同频段的可重构和可调谐地面天线。地面天线特别适用于4G超薄手持设备，特别是柔性或可弯曲设备。地面天线也很有希望在小型手持设备中形成高隔离天线系统，用于MIMO和分集操作。

Keynote speaker 3: Handheld communication device ground antennas: Advances and perspectives

Ground antenna concept and its promising applications for handheld communication devices such as the smartphones and tablet computers will be presented. The ground antennas are formed by adding very-small-size radiating elements to combine with the device ground plane to achieve an efficient radiator for multiband/wideband operations. Recent advances in the ground antenna design are addressed. The reconfigurable and tunable ground antennas that can be adaptive to environmental changes or tunable to cover different bands will be discussed. The ground antennas are especially suitable for applications in the 4G slim handheld devices, especially for flexible or bendable devices. The ground antennas are also very promising to form high-isolation antenna systems for MIMO and diversity operations in the slim handheld devices.
