Abstract: An antenna element for a multi-band antenna device includes a dielectric body provided with one or more metal layers. The dielectric body includes a base plate and one or more wall elements arranged on the base plate. One or more first radiating elements and one or more second radiating elements are arranged on the base plate, and are configured to radiate in a first and a second frequency band, respectively. A first feeding network is connected to the first radiating elements and a second feeding network is connected to the second radiating elements, for operating the first and second radiating elements as a first and second antenna array, respectively. The first feeding network is provided, at least partly, as a metal layer of the one or more metal layers on the one or more wall elements.

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 two-dimensional antennas and network devices. One example antenna includes a reflection panel, at least two antenna arrays, at least one common feeding network, and at least two array feeding networks. The at least two antenna arrays are on the reflection panel. Each antenna array comprises at least one independent radiation unit and at least one common radiation unit. Each antenna array corresponds to an array feeding network of the at least two array feeding networks. Each independent radiation unit in each antenna array is connected to a particular array feeding network corresponding to the particular antenna array. Each common radiation unit in each antenna array is connected to the at least one common feeding network. The at least one common feeding network is connected to the at least two array feeding networks corresponding to the at least two antenna arrays.

Abstract: The present disclosure relates to multiband antenna apparatuses. An example multiband antenna apparatus includes a first dipole radiating element, a second radiating element, and a metasurface superstrate (MSS) structure. The first dipole radiating element may be configured to operate at a first frequency band and arranged on an upper plane of a support structure in a first distance to a reflector plate. The second radiating element may be configured to operate at a second frequency band and arranged on a lower plane of the support structure in a second distance to the reflector plate. The second distance is smaller than the first distance. The second frequency band is higher than the first frequency band. The MSS structure is arranged in an area inside arms of the first dipole radiating element and enhances a performance of the second radiating element.
