R04534 High Frequency PCB Material Introduction RO4534 High Frequency Laminates are ceramic-filled, glass-reinforced hydrocarbon based material which are cost/performance materials from Rogers Corporation, specifically engineered and manufactured to meet the specific demands of the antenna markets. It has a dielectric constant of 3.4 and a loss tangent (Df) of 0.0027 measured at 10GHz. These values allow antenna designers to realize substantial gain values while minimizing signal loss. Thus, it provides excellent passive intermodulation response required for mobile infrastructure microstrip antenna applications. It is an affordable alternative to more conventional PTFE antenna technologies, thus allowing our designers to optimize the price and performance of the antennas. The resin systems of RO4534 dielectric materials are designed to provide the necessary properties for ideal antenna performance. The coefficients of thermal expansion (CTEs) in both the X and Y directions are similar to that of copper. The good CTE match reduces stresses in the printed circuit board antenna.
