Abstract: In embodiments, an electronic device may include a housing having an inner space, a printed circuit board (PCB) disposed in the inner space of the housing, a first antenna structure disposed at a position spaced apart from the PCB, and transmitting and/or receiving a radio signal in a first frequency band, at least one second antenna structure disposed at a position spaced apart from the PCB, and transmitting and/or receiving a radio signal in a second frequency band different from the first frequency band, and a flexible substrate electrically connecting the PCB and the first antenna structure.

Abstract: The present disclosure provides an apparatus for measuring three-dimensional shapes by using moire interference, which comprises a unit calibration unit, an integrated calibration unit and a phase calibration unit. The unit calibration unit is configured to use a phase difference between two adjacent measuring points for obtaining a unit calibration value of an absolute moire order. The integrated calibration unit is configured to calibrate the absolute moire order up to a target point by using the unit calibration values. The phase calibration unit is configured to calibrate a phase of the target point by using the absolute moire order.
