Abstract

The present disclosure relates to a balun arrangement (14) comprising a slot (5) at least partially having a crossing slot width (ws, hs) running between a first longitudinal side (6) and a second longitudinal side (7) in at least a first metallization layer (2). The balun arrangement (14) further comprises an unbalanced first port (P1) that is defined between a first connection (10) to the second side (7) of the slot (5) and a fourth connection (21) to the first side (6) of the slot (5) and a balanced second port (P2) that is that is defined between a second connection (11) to the second side (7) of the slot (5) and a fifth connection (22) to the first side (6) of the slot (5). The balun arrangement (14) also comprises a balanced third port (P3) that is defined between a third connection (12) to the first side (6) of the slot (5) and a sixth connection (23) to the second side (7) of the slot (5).

Dependent claims

A balun arrangement comprising a slot at least partially having a crossing slot width (ws, hs) running between a first longitudinal side and a second longitudinal side in at least a first metallization layer, where the balun arrangement further comprises:

an unbalanced first port (P1) that is defined between a first electrical connection to the second longitudinal side of the slot and a fourth electrical connection to the first longitudinal side of the slot,
a balanced second port (P2) that is defined between a second electrical connection to the second longitudinal side of the slot and a fifth electrical connection to the first longitudinal side of the slot, and
a balanced third port (P3) that is defined between a third electrical connection to the first longitudinal side of the slot and a sixth electrical connection to the second longitudinal side of the slot, wherein:
the first electrical connection runs from a first type terminal (+) of the first port (P1) to a first ground connection at the second side of the slot, and the fourth electrical connection runs from a second type terminal (−) of the first port (P1) to a fourth ground connection at the first longitudinal side of the slot,
the second electrical connection runs from a first type terminal (+) of the second port (P2) to a second ground connection at the second side of the slot, and the fifth electrical connection runs from a second type terminal (−) of the second port (P2) to a fifth ground connection at the first longitudinal side of the slot, and
the third electrical connection runs from a first type terminal (+) of the third port (P3) to a third ground connection at the first longitudinal side of the slot, and the sixth electrical connection runs from a second type terminal (−) of the third port (P3) to a sixth ground connection at the second side of the slot.
