为实现全印制柔性射频微带线(RF MSLs)在应用中的相位可调特性,通过引入分子链柔顺性好的聚醚胺D-230固化剂,开发了一种可靠性较高的相位调制胶,探究了该相位调制胶的相位调制机理、可靠性以及对柔性射频微带线性能的影响.结果表明,所制相位调制胶具有良好的介电性能、机械性能、热稳定性和较低的吸水率,其中介电常数和介电损耗在1~4 GHz频段内分别小于2.5和2.2.在此基础上,通过在印刷制备的RF MSLs表面铜导线上微量(约1 mg)涂敷相位调制胶,成功实现了微带线的相位可调功能,在4 GHz下的相位滞后值为14.1°.该工艺成本低廉、操作灵活,无需外设刚性移相器或移相网络,即可实现相位的灵活调制,为柔性射频器件的相位一致性调节提供了新思路.
Properties of phase-modulable sealant of flexible RF microstrip line
To meet the phase-modulable characteristics of all-printed RF MSLs in application,the curing agent polyetheramine D-230 with good molecular chain flexibility was introduced to prepare a high-reliability phase-modulable sealant.The phase modulation mechanism,reliability,and its effect on the performance of the RF MSLs were investigated.The results show that this sealant exhibits superior dielectric properties,mechanical properties,thermal stability with low water absorption.The dielectric constant and dielectric loss are below 2.5 and 2.2 in the 1-4 GHz frequency range,respectively.Furthermore,the obtained RF MSLs realize phase-modulable characteristics by applying a small amount(approximately 1 mg)of the sealant to their surface.The value of the phase lag at 4 GHz is 14.1°.The process exhibits low cost and flexible operation,and the flexible modulation of phase can be realized without external rigid phase shifters or phase-shifting networks.This study provides an innovative approach for the phase consistency adjustment of the flexible radio frequency devices.
