Latest Patents

Dacheng Wei's latest patents include a device and method for reducing mutual coupling of two antennas by adding capacitors on the ground. This invention allows radio frequency antennas sharing a ground plane to be largely decoupled using one or more lumped capacitive elements set into holes within the ground plane. The holes are precisely placed and can extend to a side of the ground plane. A stub extends from a fringe of the hole either straight or bending in an L shape, with a capacitor connecting between an end of the stub and another side of the hole. Additionally, capacitive elements can be supported on raised solder pads above a ground plane or off to one side of the ground plane. Methods for manufacturing the decoupling apparatus are also described.

Another notable patent is the double torsion coil magnetic current antenna feeding structure. This invention features a magnetic current dipole feeding structure for patch and dielectric resonator antennas. A wire coil helix is placed above the ground plane and below the patch or top of the dielectric resonator block. The coil has half wound in a right-hand orientation and another half in a left-hand orientation, meeting at a common point in the middle. One end of the double torsion coil can be excited with radio frequency (RF) signals, while the other can be grounded on the ground plane. Some embodiments have the other end fed by an equal signal. These double torsion coils can be used in pairs to provide differential feeding to the patch or dielectric resonator, with pairs placed orthogonally to a first pair for another polarization.
