Abstract
Provided is a balun structure, including: a first dielectric layer, a second dielectric layer, a ground electrode, an unbalance electrode, and a balance electrode. The first dielectric layer, the ground electrode, the second dielectric layer are successively stacked, and the ground electrode has a coupling hole therein. The coupling hole extends from a surface facing the first dielectric layer to a surface facing the second dielectric layer. The unbalance electrode is disposed on a first side of the first dielectric layer, wherein the first side of the first dielectric layer is a side, distal from the ground electrode, of the first dielectric layer. The balance electrode is disposed on a first side of the second dielectric layer, wherein the first side of the second dielectric layer is a side, distal from the ground electrode, of the second dielectric layer.
