Title: MULTI-ANTENNA TRANSMISSION AND RECEPTION DEVICE
Abstract:
A multi-antenna transmission device of the present invention can comprise: an RF resonator for generating a reference signal in a carrier frequency; a power amplifier for amplifying the generated reference signal to a signal of a preset magnitude; N number of switches for individually adjusting the magnitude of a transmission signal for each channel to be wirelessly transmitted, on the basis of the amplified reference signal for each channel; N number of inverters for individually determining a sign of the magnitude-adjusted transmission signal for each channel; and a transmission antenna integrated structure in which N number of antennas having different patterns and polarization characteristics individually and wirelessly transmit the determined transmission signal for each channel in different radiation patterns.
