What is RT duroid substrate?
RT Duroid is Glass Microfiber Reinforced PTFE (polytetrafluoroethylene) composite produced by Roger Corporation. RT Duroid 5870 substrate has low loss tangent.
What is 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.
Is RT Duroid flexible?
The antenna is designed using RT/duroid 5880 (ε r = 2.2 and h = 0.381mm), a thin and flexible substrate suitable for wearable antennas in body area networks and FR4 substrate (ε r = 4.6 and h = 1.6mm).
What is Rogers PCB material?
Rogers is a company that manufactures the laminate materials which is used for manufacture electronic circuit boards . Most PCBs are made of a material known as FR4 (Flame Retardant level 4), which is a composite of glass fiber/epoxy, with copper foil laminated on one or both sides.
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.
What is substrate in antenna?
A dielectric substrate is a insulator which is a main constituent of the microstrip structure, where a thicker substrate is considered because it has direct proportionality with bandwidth whereas dielectric constant is inversely proportional to bandwidth as lower the relative permittivity better the fringing is …
Is Rogers 5880 flexible?
RT/duroid material cut cleaner and faster without warpage, a significant advantage over woven glass substrates. Flexibility of the RT/duroid 5880 material enabled American Nucleonics to then form the etched, trimmed substrate around a pre-molded dielectric foam cone and secure in place.
What is Duroid?
What is a Rogers board?
The Rogers Board of Directors is elected by the shareholders to oversee the management of the company and to assure that shareholder interests are being served. The Board is mainly comprised of outside, independent directors. It regularly meets in executive session, without the presence of Rogers’ management.
What is FR4 substrate?
What is FR4? FR4 is the most common material grade that comprises fabricated circuit boards. ‘FR’ indicates the material is flame retardant and the ‘4’ indicates woven glass reinforced epoxy resin. Single or double-sided PCB structures consist of an FR4 core and top and bottom copper layers.
Why do we use substrates?
In atomic layer deposition, the substrate acts as an initial surface on which reagents can combine to precisely build up chemical structures. A wide variety of substrates are used depending on the reaction of interest, but they frequently bind the reagents with some affinity to allow sticking to the substrate.
Why we use FR4 substrate?
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.
