Abstract: Technologies directed to a hybrid-feed network of a parallel feed network and series-fed sub-arrays are described. The hybrid-feed network includes a parallel feed network and multiple groups of series-fed tiles, each tile including a beamforming integrated circuit (IC) and a set of antenna elements.

Abstract: Technologies directed to calibrating phased array antennas are described. A processing device of a communication device causes a first radio to send a first signal via a first antenna element. The first signal has a set of tones. Each tone of the set of tones has a frequency within a fixed frequency range. The processing device causes a second radio to receive a second signal via a second antenna element. The second signal is a response to the first signal. The processing device determines that there is a difference between the second signal and a reference signal. The processing device adjusts at least one of a phase parameter value, a gain parameter value, or a time-delay parameter value of a radio frequency component based on the difference.

Abstract: Technologies directed to arranging antenna elements in a triangular pattern on an antenna module of a phased array antenna are described. The phased array antenna includes a support structure and a first antenna module coupled to the support structure. The first antenna module element has a rectangular shape and includes a first set of antenna elements arranged as a first row and a second row within the rectangular shape. An antenna element of the first row and two antenna elements of the second row form a triangular pattern. Two adjacent antenna elements of the first set of antenna elements are separated by a first distance. Each antenna element of the first set of antenna elements has a first size that is less than half of the first distance.
