Abstract: A patch array has a routing printed circuit board with a plurality of layers for routing signals, and a plurality of printed circuit board patches that each has at least one through-via. The plurality of patches are mounted with the routing printed circuit board. In addition, the plurality of printed circuit board patches are formed in compliance with standard printed circuit board rules.

Abstract: A symmetric, multi-layer, three-way power divider that is equally balanced, with resistors placed between all combinations of legs. This three-way power divider is specifically designed to be used in millimeter wave applications (e.g., 5G in the 20 GHz-40 GHz range for both dual and single polarization), specifically in designs where a common signal is distributed to a multiple of three elements. This three-way power divider also can be useful for addressing space constraints in 5G applications, e.g., due to routing limitations.

Abstract: A phased array type antenna apparatus compensates for phase and time differences between signals received at different elements of the antenna. Each element within the antenna apparatus has an associated phase/time adjuster circuit. The signals from each element are divided, with the first output routed to a combining circuit. The second output of one element is used as a reference signal, with the second output from the remaining elements routed to a switch. One signal is selected at the switch, and is used as a non-reference signal. Phase difference between the reference signal and the non-reference signal is determined at a comparator circuit, and the phase/time adjuster circuit associated with the non-reference signal is adjusted to bring the two signals into phase alignment. Time difference between the reference and non-reference signal is determined using dual correlators and a comparator circuit.
