摘要： There is provided a beam steerable antenna system including: an antenna array including a plurality of first radiating elements; a first phase control section coupled to the plurality of first radiating elements, the first phase control section being configured to control a phase of signals from the plurality of first radiating elements to output first phase controlled signals; a first combiner coupled to the first phase control section, the first combiner being configured to combine the first phase controlled signals to output a first combined signal; a first frequency converter coupled to the first combiner, the first frequency converter being configured to downconvert a frequency of the first combined signal to output a first downconverted signal; and a second phase control section coupled to the first frequency converter, the second phase control section being configured to control a phase of the first downconverted signal to output a second phase controlled signal. There is also provided a method of manufacturing the beam steerable antenna system, and a method of beam steering an antenna array.
