Abstract: An example antenna structure comprises a plurality of radiators arranged with space between one another. A distance between adjacent radiators of at least some of the plurality of radiators is greater than one wavelength of a highest frequency of an operating band of the antenna structure. A reflector is disposed beneath the plurality of radiators, and a metasurface structure is disposed above the plurality of radiators.

Abstract: The present disclosure relates to antenna devices and arrays of antenna devices. One example antenna device includes a first radiator configured to radiate a first electromagnetic signal, a second radiator configured to radiate a second electromagnetic signal, and a joint feeding network including a first 180-degree coupler and a second 180-degree coupler arranged in sequence. The first 180-degree coupler receives first input signal and second input signal, and the second 180-degree coupler provides first output signal to the first radiator and second output signal to the second radiator. In the joint feeding network, a first path connects the first 180-degree coupler to the second 180-degree coupler including a first phase shifter. A second path connects the first 180-degree coupler to the second 180-degree coupler including a second phase shifter and an attenuator.
