1. An ultra-wide-band uniplanar magic T consisting of coplanar wave guides, slot lines and air bridges as mode filters is studied.

2. Recently, uniplanar antennas have been used in many applications in millimeter-wave systems.

3. A uniplanar capacitive sensor, with 8-electrode on one plane substrate, is designed to detect the subsurface anomalies or damage of non-metallic materials.

4. A uniplanar multi-electrode configuration is designed to detect the structure anomalies of non-metallic material component.

5. Aiming at the feature of fully open magnetic resonance imaging system, a new approach to the design of uniplanar gradient coils was proposed.

6. To diminish the influence of the eddy currents, the design method of self-shielded gradient coils is studied and the self-shielded uniplanar gradient coils are designed in this paper.
