Abstract
Examples disclosed herein relate to an antenna system. The antenna system has a transceiver unit adapted to receive a composite communication signal, wherein the composite communication signal is a mix of multiple individual communication signals transmitted at different frequencies, a radiating structure comprising multiple subarrays of radiating elements, each subarray responsive to a different frequency, and an antenna controller adapted to map each communication signal to a user equipment and adjust an electrical parameter of the radiating elements within each subarray so as to direct each individual communication signal in the composite communication signal to a corresponding user equipment.
Claims20
A frequency-selective antenna system, comprising:
- a transceiver unit adapted to receive a composite communication signal, wherein the composite communication signal is a mix of multiple individual communication signals transmitted at different frequencies;
- a radiating structure comprising multiple subarrays of radiating elements, each subarray responsive to a different frequency;
- and
- an antenna controller adapted to map each communication signal to a user equipment and adjust an electrical parameter of the radiating elements within each subarray so as to direct each individual communication signal in the composite communication signal to a corresponding user equipment.
A frequency-selective metastructure antenna, comprising:
- a first set of metastructure cells responsive to a first frequency;
- a second set of metastructure cells responsive to a second frequency;
- and
- a set of electrical parameter control devices, wherein each electrical parameter control device is to alter an electrical parameter of at least one metastructure cell.
A method for frequency-selective transmissions from a metastructure antenna to a user, comprising:
- directing a transmission to a first user;
- assigning a first frequency to the transmission to the first user;
- generating the transmission at the first frequency;
- and
- controlling a frequency-selective first subarray of metastructure cells to direct the transmission to the first user.
The method of claim 20, wherein controlling a frequency-selective first subarray of metastructure cells comprises controlling a reactance of each metastructure cell.
