An antenna of this invention comprises an antenna element to which power is fed at a feed point; and a ground pattern that is juxtaposed with the antenna element and in which a tapered shape is formed with respect to the feed point of the antenna element. By providing the tapered shape for the ground pattern, it is possible to appropriately adjust the coupling degree with the antenna element, thereby it is possible to widen the bandwidth. Moreover, since the ground pattern and the antenna element are juxtaposed with each other, miniaturization can be achieved. When the antenna element is integrally formed in a dielectric substrate, further miniaturization can be achieved. Furthermore, when a cut-out portion is formed in the antenna element, the characteristic of the antenna in the low frequency range is improved.

Dielectric resonators and circuits made therefrom
InactiveUS7310031B2High quality factor per unit volumeCompact designResonatorsDielectric resonator antennaCoupling
A dielectric resonator having variable cross-section, preferably varying monotonically, and, most preferably, the resonator being in the shape of a truncated cone. Such shapes displace the H11 mode from the TE mode in the longitudinal direction of the cone. Truncating the cone to eliminate the portion of the cone where the H11 mode exists, virtually eliminates the H11 mode. A circuit comprising a plurality of these resonators may be arranged in an enclosure with each resonator longitudinally inverted relative to adjacent resonator(s) to provide a compact design with enhanced coupling and adjustability. A spiral coupling loop provides high magnetic flux in a small physical volume for coupling energy into or out of the circuit. Alternately, the resonator can coupled to a microstrip by placing the resonator upside-down near the microstrip, whereby the TE mode is immediately above the microstrip, providing enhanced coupling there between.

Silicone release polyester film
InactiveUS20050118443A1High viscosityLow viscositySynthetic resin layered productsRecord information storagePolyesterAdhesive
The invention illustrates herein several tests among various manufacturing methods and tests carried out by the inventors according to the method of manufacturing a silicone release polyester film. It should be noted that the technical spirit of the invention shall not be limited or restricted thereby, and can be modified and carried out variously by those skilled in the art. As described in the above, the silicone release polyester film according to the invention is very good in stabilization for pass-the-time and also very good in the property of rub-off after thermal ripening by improving adhesiveness between the polyester layer and the silicone layer by olgano resin having the vinyl radical in the silicone film layer. By improving easiness of release destruction behavior with the adhesive used for release by containing the olgano resin having the vinyl radical in hexenyl polysiloxane, the silicone release polyester film can be used for electronics and the field requiring uniform release. The silicone release polyester film according to the invention can solve the problems of weakened adhesiveness on an adhesive layer combined with the silicone layer resulting from silicone transfer in a process and of bad printing on the surface opposite to the adhesive layer, by allowing the property of minimized silicone transfer in which the content of silicone residue is below 10% by means of excellent silicone hardening.
