Abstract
A phased array module includes a plurality of antenna boards. Each antenna board has an identical layout and has a plurality of antenna elements so positioned that together they form a matrix pattern on the antenna board and an integrated circuit containing a plurality of transceiver devices. Each transceiver is connected with an antenna element on the antenna board, such that corner antenna elements of three adjacent antenna boards of the plurality form an equilateral triangle. The matrix pattern formed by the plurality of antenna elements is square-shaped or rectangular-shaped.

A phased array module comprising a plurality of antenna boards, each antenna board having an identical layout, and said antenna board comprising a plurality of antenna elements positioned to form together a matrix pattern on said antenna board and an integrated circuit containing a plurality of transceiver devices, each transceiver in said plurality of transceiver devices is connected with an antenna element on said antenna board,
- wherein corner antenna elements of three adjacent antenna boards of said plurality of antenna boards form an equilateral triangle,
- wherein said matrix pattern formed by said plurality of antenna elements is square shaped or rectangular shaped.
A method for calibrating a pair of antenna elements of a phased array module, said phased array module including a plurality of antenna boards, each antenna board having an identical layout, and said antenna board having a plurality of antenna elements positioned to form together a matrix pattern on said antenna board, said phased array module further including an integrated circuit containing a plurality of transceiver devices, each transceiver in said plurality of transceiver devices is connected with an antenna element on said antenna board, wherein corner antenna elements of three adjacent antenna boards of said plurality of antenna boards form an equilateral triangle, wherein said matrix pattern formed by said plurality of antenna elements is square shaped or rectangular shaped, the method comprising:
- selecting in said phased array module two antenna paths to be calibrated, each antenna path comprising an antenna element of said pair and an RF frontend to which said antenna element is connected,
- selecting in said phased array module a further antenna element as reference antenna in a reference antenna path, said reference antenna path also comprising a RF front end to which said reference antenna is connected,
- wherein said reference antenna is so positioned that the geometric distance to said two antenna paths is the same,
- calibrating said pair of antenna elements by using the two antenna paths for transmitting a signal and the reference antenna path for receiving the transmitted signal, or vice versa,
- wherein the transmitted signal propagates through antenna spill over.
