Kind Code:
A1
Abstract:
In order to transmit/receive desired radio waves at the same time between a plurality of communication targets while establishing both gain and a communication number, the present invention provides a transmitter/receiver comprising: a spherical radio wave lens having formed therein a meta surface that condenses the desired radio waves to be transmitted/received; and a plurality of array antennas that are disposed facing a transmission/reception surface of the spherical radio wave lens and are disposed so that antenna units that transmit/receive the desired radio waves to be transmitted/received match the focal position of the spherical radio wave lens.
