What is RT Duroid?

Rogers RT/duroid® high frequency circuit materials are filled PTFE (random glass or ceramic) composite laminates for use in high reliability, aerospace and defense applications. The RT/duroid series has a long industry presence of providing high reliability materials with superior performance.

Why does Rogers RT Duroid 5880?

Rogers RT/duroid 5880 high frequency laminates are PTFE composites reinforced with glass microfibers. RT/duroid 5880 laminates has a low dielectric constant (Dk) and low dielectric loss, making them well suited for high frequency/broadband applications.

What is RT Duroid 5870?

Rogers RT/duroid 5870 high frequency laminates are PTFE composites reinforced with glass microfibers. With its low Dk loss, RT/duroid 5870 laminates are well suited for high frequency/broadband applications where dispersion and losses need to be minimized.

What is Rogers PCB material?

Rogers PCB are hydrocarbon ceramic laminates and gave upper level ability to operate at high frequency, yield better result and reduced cost printed circuit fabrication which make it thermally stable and reduce the electrical losses (signal loss). standard epoxy/glass (FR-4) method is used for fabrication.

What is FR4 substrate?

FR-4 (or FR4) is a NEMA grade designation for glass-reinforced epoxy laminate material. FR-4 is a composite material composed of woven fiberglass cloth with an epoxy resin binder that is flame resistant (self-extinguishing). Of these, FR-4 is the grade most widely in use today.

What is Rogers substrate?

Rogers RO4000 hydrocarbon ceramic laminates and prepregs are the industry leader. Used in microwave and millimeter wave frequencies, this low loss material offers easier use in circuit fabrication and streamlined properties over traditional PTFE materials.

What is the difference between FR4 material and Rogers material?

The difference between FR-4 material and Rogers material FR-4 material is cheaper than Rogers material. In impedance stability, Rogers material has a wider range of Dk values than FR-4 material. 5. For dielectric constant, FR-4 features a Dk of about 4.5, which is lower than Rogers material with around 6.15 to 11.

Why we use FR4 epoxy?

With near zero water absorption, FR-4 is most commonly used as an electrical insulator possessing considerable mechanical strength. The material is known to retain its high mechanical values and electrical insulating qualities in both dry and humid conditions.

Who invented patch antenna?

Robert E Munson
Just stumbled up on the news that Robert E Munson (“Bob Munson”) passed away on August 31, 2015. He is the inventor of what is popularly known as “microstrip patch” antenna.
