摘要： Proposed is a position measuring device configured to measure a position (distance) by combining a TWR positioning method and a PDOA positioning method. The proposed position measuring device: outputs positioning signals at set time intervals; receives response signals for the positioning signals; measures the distance between a plurality of diversity antennas and an object on the basis of the respective positioning signals and response signals transmitted and received by the diversity antennas; and measures the distance to the object on the basis of the measurement values of the distances between the plurality of diversity antennas and the object.

摘要： Disclosed is a UWB antenna module arranged in the lateral direction of a portable terminal so as to prevent deterioration of communication performance while minimizing a mounting space. The disclosed UWB antenna module comprises: a planar base substrate; a plurality of radiation patterns arranged on the upper surface of the base substrate, and arranged so as to be spaced from each other; a switching element arranged on the lower surface of the base substrate and connected to the plurality of radiation patterns; and a communication chipset arranged to be spaced from the switching element on the lower surface of the base substrate, and connected to one of the plurality of radiation patterns through a switching operation of the switching element.
