Abstract
A power combiner/splitter for multiple input multiple output (MIMO) applications and a method of making the same. A metallisation stack has a plurality of layers including patterned metal features forming first and second branched arrangements of the power combiner/splitter. Each branched arrangement includes a port located at one end of that branched arrangement, and a plurality of further ports. Each branched arrangement also includes a plurality of bifurcated branches extending between each end of that branched arrangement for dividing/combining a signal passing through that branched arrangement between the port and the plurality of further ports. The metallisation stack further includes a common ground plane that is shared by the first and second branched arrangements. At least some of the patterned metal features forming the first branched arrangement overlie at least some of the patterned metal features forming the second branched arrangement.
