LTCC 공정을 이용한 K/Ka 대역 송수신 겸용 이중 급전 안테나 = Design of Tx/Rx Broadband Antenna on LTCC at K/Ka Band

다국어 초록 (Multilingual Abstract)

The Ku band that has been using for the satellite communication and broadcasting would be changed to K/Ka bands. The satellite system requires the antenna structure to fabricate low loss and small antenna that is able to be integrated with other Rf circuits for both Rx and Tx. So we should design it with dual feed antennas at K/Ka bands, high isolation between two different feeds and broadband circular polarization. This paper proposes the LTCC(Low Temperature Co-fired Ceramic) process for integration with other Rf circuits and the Axial mode of the helical antenna to satisfy those requirements.
