摘要： A measurement apparatus outputs from a first antenna pair transmission signals (St11) and (St12) whose phase difference (Δφ1) changes over time. A target object simultaneously receives the transmission signals (St11) and (St12) from a target-side antenna and returns to the measurement apparatus information (Dφ) according to the positional relationship between the target object and the measurement apparatus determined from a reception signal (Sr1). The measurement apparatus outputs from a second antenna pair transmission signals (St21) and (St22) whose phase difference (Δφ2) changes over time. The target object simultaneously receives the transmission signals (St21) and (St22) from the target-side antenna and returns to the measurement apparatus the information (Dφ) corresponding to the positional relationship between the target object and the measurement apparatus determined from a reception signal (Sr2). The measurement apparatus identifies a direction (θ) of the target object on the basis of these two pieces of information (Dφ).

摘要： Two antennas receive three kinds of radio waves with different frequencies. A computation unit determines the arrival direction of the three kinds of radio waves arriving at the two antennas after propagating along two mutually different paths from a single transmit point in accordance with receive signals of the three kinds of radio waves with different frequencies received individually by the two antennas.

摘要： A heartbeat measurement device includes a transmitter configured to transmit a transmission signal from a transmission antenna to a person to be measured, a receiver configured to receive a signal reflected from the person to be measured as a reception signal using a reception antenna, and an orthogonal detection circuit configured to generate an I signal that is an in-phase component of the transmission signal and the reception signal and a Q signal that is a quadrature component of the transmission signal and the reception signal. The heartbeat measurement device further includes a Fourier transform unit configured to calculate a spectrum in positive and negative frequency domains on the basis of the I signal and the Q signal and a signal processing unit configured to compare positive and negative frequency components in the spectrum to extract a heartbeat component.

摘要： A position detection system includes a mobile station, a reference station, fixed stations to, and a server. The mobile station transmits a first radio signal S1 and the reference station transmits a second radio signal S2 multiple times. Each of the fixed stations extracts a first phase difference based on the first radio signal S1 and extracts second phase differences based on the second radio signals S2. The server calculates time variations of the second phase differences based on the multiple second phase differences to calculate a third phase difference. The server cancels phase offset by the respective fixed stations using phase difference information between the mobile station and the respective fixed stations and phase difference information between the reference station and the respective fixed stations and acquires distance information between the respective fixed stations and the mobile station to calculate the position of the mobile station.

摘要： A semiconductor component is face-up mounted on a package substrate. An antenna substrate is flip-chip mounted on a front side of the semiconductor component. A device-side high-frequency signal terminal is disposed on the front side of the semiconductor component, and an antenna-side high-frequency signal terminal is disposed on a back side of the antenna substrate. The device-side high-frequency signal terminal and the antenna-side high-frequency signal terminal are electrically connected to each other. Thus, the antenna substrate for high-frequency signals can be separated from the package substrate for baseband signals.
