A HIGH FREQUENCY COPLANAR STRIP TRANSMISSION LINE ON A LOSSY SUBSTRATE

摘要

A substrate (12) having two high frequency components (28, 30, 34, 36, 48) positioned on substrates (12) typically used for lower frequency devices. A coplanar strip transmission line (38, 40, 46, 52, 58), providing for transmission of high frequency signals, comprises first, second and third parallel, spaced conductive traces (62, 64, 66) positioned on a surface (11) of the substrate (12), wherein the substrate (12) defines a first slot (68, 72, 76) extending from the first surface (11) into the substrate (12) and between the first and second parallel, spaced conductive traces (64, 62), and a second slot (70, 74, 78) extending from the first surface (11) into the substrate (12) and between the first and third parallel, spaced conductive traces (64, 66). Optionally, an antenna (42, 44, 54, 56) is coupled to the coplanar strip transmission line (46, 58) and comprises first and second antenna traces (41, 43), the substrate (12) defining a third slot (45) therebetween.
