Abstract: The present invention relates to a transmitting device and a receiving device. The transmitting device includes a controller, at least a feeding antenna and a plurality of transceiving modules. The controller generates a plurality of set of module control signals; the feeding antenna radiately transmits at least an internal transmission signal. Each transceiving module includes a plurality of transceiving units, and each transceiving unit includes a radiation slice and a transceiving circuit. A lengthwise edge of the radiation slice has a first end and a second end, and the first end and the second end of the lengthwise edge are toward an inner lateral side and an outer lateral side, respectively. The transceiving module performs transmission operation or reflection operation according to the module control signals.

Abstract: The present invention relates to a transmitter and a receiver including multiple first and second transceiving units. Each of the first and the second transceiving units includes a first and a second radiation slices and a first and a second transceiving circuits disposed thereon. In the transmitter, the first and the second transceiving units receive first and second internal transmission signals at first and second polarization from the first and the second radiation slices, and transmit first and second external transmission signals generated from transformation through the first and the second radiation slices. In the receiver, the first and the second transceiving units receive first and second external reception signals at first and second polarization through the first and the second radiation slices, and transmit first and second internal reception signals at first and second polarization generated from transformation through the first and the second radiation slices.
