Patent number: 9537224Abstract: Systems, methods, devices and apparatuses directed to transceiver devices are disclosed. In accordance with one method, a first set of antenna positions in a first section of a set of sections of a circuit layout for the circuit package is selected. The method further includes selecting another set of antenna positions in another section of the circuit layout such that an arrangement of selected antenna positions of the other set is different from an arrangement of selected antenna positions of a previously selected set of antenna positions. The selecting another set of positions in another section is iterated until selections have been made for a total number of antennas. The selecting the other set is performed such that consecutive unselected positions in the other section do not exceed a predetermined number of positions. In addition, antenna elements are formed at the selected positions to fabricate the circuit package.Type: GrantFiled: May 29, 2015Date of Patent: January 3, 2017Assignee: International Business Machines CorporationInventors: Daniel J.
