METHODS FOR SLOT ANTENNA DESIGN FOR WEARABLE ELECTRONIC DEVICES AND CONDUCTIVE HOUSINGS

A wearable computing device can include a slot antenna formed by a gap between a housing (such as a highly conductive housing) and a PCB within the highly conductive housing and by a back cavity between the highly conductive bracket and PCB or by a back cavity between the highly conductive bracket and the highly conductive housing. The printed circuit board is coupled to either the highly conductive bracket or highly conductive housing through a matching circuit and direct feed. The PCB is positioned near a display window of the device, above a battery and highly conductive bracket. This configuration allows for a relatively small dead band in the display window, a larger PCB, compact and mechanically simple configuration, and superior water resistance. 一种可穿戴计算设备，可包括缝隙天线，所述缝隙天线由以下形成：壳体(诸如高导电性壳体)和高导电性壳体内的PCB之间的间隙，以及高导电性支架和PCB之间的背腔，或者高导电性支架和高导电性壳体之间的背腔。印刷电路板通过匹配电路和直接馈电耦接到高导电性支架或高导电性壳体。所述PCB定位在所述设备的显示窗口附近，在电池和高导电性支架的上方。这种配置允许在显示窗口中具有相对小的死区、更大的PCB、紧凑且机械上简单的配置以及优异的防水性。
