"As cellphones and electronic devices moves towards higher date rates yet smaller form factor, designer face more electromagnetic interference (EMI) and radio frequency interference (RFI) problems. In order to better guide the early design; designers want to know the exact electrical performance of small components, coupling estimation between components.

In Section 1, a de-embedding method is proposed to measure the impedance of an innovative O-shape spring contact, for frequency up to 30 GHz. The measurements are performed under the same condition when it's actually used in cellphones. De-embedding method will be applied to remove the fixture effects of the measurement setup, hence only the electrical performance of the DUT is obtained.

In Section 2, a dipole moment model is studied to investigate the near field RF coupling. A set of dipoles (both electric dipoles and magnetic dipoles) will be used to fit the measured tangential H field of the near field scanning. The dipoles will be built in 3D simulation tool. Together with the nearby antenna, the coupling between the dipole source and the victim antenna can be obtained. This dipole moment method is verified by both measurement and direct simulation data"--Abstract, page iii.
