Abstract

The application provides a signal transceiving method and device and a planar phased array antenna, and relates to the technical fields of communication and radar.The method comprises the following steps: receiving a first signal by the antenna unit, the first signal being used for representing an electromagnetic signal arriving at the antenna of the device; performing signal processing on the first sub-signal by the TR component to obtain a first sub-signal, the first sub-signal corresponding to the antenna unit in one-to-one manner; after delay and amplification processing, the first sub-signals are connected in series to obtain an output signal of the planar phased array antenna; by changing the parameter setting of the TR component, the beam pointing direction of the planar phased array antenna is adjusted to realize the reception of the signal of the target direction.The application proposes a planar phased array antenna based on series feeding, realizes two-dimensional scanning of the antenna directional diagram, and can be applied to different application scenarios of high integration, low profile and miniaturization.
