MAGTREX 555
材料的核心是由專有的低損耗、高電阻率陶瓷填料和高溫熱塑性基體制成，這種組合產生了一個在機械和電氣上都穩定的系統。層壓板的X/Y軸磁導率和介電常數緊密匹配，分別為6和6.5，且在低于500
MHz的頻率下具有低磁損耗和介電損耗。此外，MAGTREX 555 層壓板具有低X、Y、Z
CTE(熱膨脹系數)，與銅緊密匹配，確保了熱可靠性，厚度范圍從40至260密耳，并可提供帶或不帶銅包層。
這種層壓板特別適合于VHF和UHF天線的小型化設計，同時保持了與更大設計相當的帶寬。MAGTREX 555 層壓板的制造工藝基于陶瓷/PTFE復合材料系統，類似于羅杰斯公司知名的RT/duroid層壓板。
MAGTREX 555 層壓板的特性包括匹配的磁導率和介電常數、高小型化系數、聚四氟乙烯復合層壓板、低吸濕性、低介電損耗和低磁損耗(低于500MHz)。這些特性帶來了多方面的好處，包括基板阻抗與空氣匹配、天線小型化和帶寬改進、靈活且貼合的設計、環境穩定的電氣性能以及高天線效率。
