Abstract: A Doppler motion sensor device is used for detecting a motion of an object. The Doppler motion sensor device includes a first antenna and a second antenna. The first antenna is used to transmit or receive a first wireless signal. The second antenna is used to transmit or receive a second wireless signal. A first straight line passing through a first feed-in point and a first middle point of the first antenna is orthogonal to a second straight line passing through a second feed-in point and a second middle point of the second antenna. One of the first wireless signal and the second wireless signal is a transmission signal. The transmission signal is reflected by the object to form the other one of the first wireless signal and the second wireless signal.

Abstract: A radar signal device includes an antenna unit, a transmission circuit and a reception circuit. The antenna unit is used to concurrently transmit a transmission signal and receive a reception signal. The antenna unit includes a metal layer, a first feed structure and a second feed structure. An opening is formed on the metal layer. A first projection of the first feed structure on the metal layer at least partially overlaps with the opening. A second projection of the second feed structure on the metal layer at least partially overlaps with the opening. The antenna unit forms a first radiation pattern used to transmit the transmission signal and a second radiation pattern used to receive the reception signal. An angle between a co-polarized electric field direction of the first radiation pattern and a co-polarized electric field direction of the second radiation pattern is between 45 degrees and 135 degrees.

Abstract: A wireless signal transceiver device includes a dual-polarized antenna, a transmission circuit, a reception circuit and a processor. The dual-polarized antenna includes a first feed zone and a second feed zone. The first feed zone is used to receive a transmission signal for the dual-polarized antenna to transmit a first wireless signal accordingly. The second feed zone is used to output a reception signal generated according to a second wireless signal. The dual-polarized antenna is used to form a first radiated electric-field having a first co-polarization according to the first wireless signal and form a second radiated electric-field having a second co-polarization according to the second wireless signal. The first co-polarization and the second co-polarization form an angle between 45 degrees to 135 degrees to each other in a far field.
