Rogers RO4500 is a family of high frequency circuit laminates developed for printed antennas. The family includes RO4533, RO4534 and RO4535. These materials use a ceramic-filled, glass-reinforced hydrocarbon thermoset system and are intended for applications such as wireless infrastructure antennas and their feed circuits.
Choose the specific antenna grade
RO4500 is a series name, so a fabrication drawing should identify the actual grade. The grades have different dielectric properties and product configurations. Rogers describes the series as compatible with conventional FR-4 processing, without the special plated-hole treatment associated with traditional PTFE laminates.
For an antenna project, compare dielectric thickness, copper foil, dielectric constant and loss at the relevant test frequency. Passive intermodulation performance also depends on the copper option and the test structure; a laminate data-sheet result is not a guarantee for a finished antenna.
Prepare the PCB specification
Record the selected grade, thickness tolerance, copper weight, board dimensions, finish and impedance requirements. Ask the fabricator to review the stackup before releasing production files, particularly when the design uses large panels or demanding PIM targets. Prototype measurements should confirm antenna matching and feed-network performance.
