Abstract: PURPOSE: A laminated transformer for high frequency is provided to ensure high impedance variation rate even in using inductor with a low capacity by using a capacitor. CONSTITUTION: A transformer is comprised of a first inductor(L1), a first capacitor(C1), a second inductor(L2) and a second capacitor(C). The first inductor(L1) has a ceramic sheet(300) which is provided with a ground terminal pattern(301) and a coil pattern(302). The first capacitor(C) has two ceramic sheets(330,340) which are provided with capacitor patterns(331,341), respectively. The second inductor(L2) has a ceramic sheet(350) which is provided with a first input terminal pattern(351) and a coil pattern(352). The second capacitor(C2) has two ceramic sheets(380,390) which are provided with capacitor patterns(381,391). Each sheet has via-holes filled with paste so that the coil patterns and capacity patterns are electrically connected via the conductive paste.

Abstract: PURPOSE: A stack-typed helical antenna is provided to transmit and receive horizontal and vertical polarization and simplify a fabricating process by forming a helical pattern on a dielectric sheet. CONSTITUTION: A stack-typed helical antenna comprises many horizontal pattern dielectric sheets; a first metalic pattern, stacked with a loop type, having a first open end and a second open end on each of the horizontal pattern dielectric sheets; a vertical via dielectric sheet inserted between each of the horizontal pattern dielectric sheets; and a second metalic pattern for coupling the first metalic pattern on a pair of the horizontal pattern dielectric sheets adjacent to the vertical via dielectric sheet by penetrating the vertical via dielectric sheet.

Abstract: 본 발명은 웨이퍼상태의 초고주파용 부품의 특성 측정시 웨이퍼와 프로브헤드의 접촉 여부를 검사하기 위한 장치에 관한 것이다. 본 발명은 균일하게 분배된 제1기준신호와 제2기준신호를 이용하여, 제2기준신호가 웨이퍼에 인가되어 반사된 반사신호와 제1기준신호를 각각 신호처리한 후 비교하여 접촉여부 확인신호를 표시수단에 인가하여 표시수단에 도시된 상태도에 따라 웨이퍼와 프로브헤드의 접촉 여부를 검사한다. 이로써 스펙트럼 분석기둥의 고가의 장비를 사용하지 않고 간단한 장치로 구성을 하여 검사비용 및 시간을 줄이고 정확하게 접촉 여부를 검사하며 잘못된 접촉방법에 따른 고가의 초고주파 프로브헤드의 손상을 미연에 방지할 수 있는 웨이퍼와 프로브헤드의 접촉 여부 검사 장치를 제공한다.
