    • A GPS receiver includes a slot antenna having first and second surfaces. The second surface includes a semi-circular portion. The first and second surfaces define a slot within which is disposed dielectric material. The slot antenna is optimized for receiving GPS signals when in proximity to a human body. The relatively compact size of the slot antenna allows for the incorporation of the antenna into a small device that can be worn on or carried in close proximity to the body of a user. This type of antenna is not as sensitive to gain variations when in the proximity of a human body because the design has a wider aperture and thus operates better near the body. Further, this type of antenna is virtually omni-directional, i.e., it is not problematically sensitive to the location of the GPS signal source. Moreover, the design is such that the antenna arrangement can be oriented within a device in a way that maximizes the number of GPS satellites tracked.
    • GPS接收机包括具有第一和第二表面的缝隙天线。 第二表面包括半圆形部分。 第一表面和第二表面限定狭缝,在该槽内设有电介质材料。 缝隙天线被优化用于在接近人体时接收GPS信号。 狭缝天线的相对紧凑的尺寸允许将天线并入可以佩戴在用户身体附近或携带的小型设备中。 当在人体附近时,这种类型的天线对于获得变化并不敏感,因为设计具有更宽的孔径并因此在身体附近更好地操作。 此外,这种类型的天线实际上是全方位的,即对GPS信号源的位置没有问题的敏感。 此外,该设计使得天线布置可以以最大化跟踪的GPS卫星的数量的方式在设备内定向。
