Rogers offers a unique portfolio of antenna-grade circuit laminates to meet the many challenges faced by antenna designers, including the demanding requirements of military antenna systems and advanced automotive radar systems. Engineered for high reliability and consistent performance with low circuit losses at high frequencies, these material solutions offer varied dielectric products for antennas, feed networks, phased arrays and radiating elements.
Rogers offers a broad range of dielectric constant and thicknesses to achieve bandwidth, gain and space requirements, at any design frequency. Options also include dielectric constant stability over temperature and precision thickness control for thick antenna structures and conformal antennas.
When choosing circuit laminate materials for phased-array antennas, dielectric constant (Dk) uniformity and low and stable loss performance are key design considerations. Rogers’ advanced materials are designed specifically for use in fabrication of antennas, multilayer RF and high speed digital boards.
Many of Rogers' “soft substrate” options are ideal for non-planar requirements and have a successful history in a variety of conformal antenna applications for simple curvatures, including small diameter cylinders.
Designs comprising complex multilayer structures are common to this set of applications. Rogers controls electrical and mechanical properties to assure phase accuracy over frequency and temperature. Low CTE and high thermal conductivity assure reliability over power cycling.
