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 Duroid substrate?
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 RT Duroid 5870?
Rogers RT/duroid 5870 high frequency laminates are PTFE composites reinforced with glass microfibers. RT/duroid 5870 laminates offer high frequency with low dielectric constant (Dk). The randomly oriented microfibers in the PTFE composites result in exceptional Dk uniformity.
What is Rogers PCB material?
Rogers PCB is a type of high-frequency board that raw material is produced by Rogers company. It is different from the conventional PCB board—epoxy resin (FR4). It has no glass fiber in the middle and uses a ceramic base as the high-frequency material. Rogers has superior dielectric constant and temperature stability.
Which are the disadvantages of microstrip antenna?
Drawbacks or disadvantages of Microstrip Antenna ➨It offers low efficiency due to dielectric losses and conductor losses. ➨It offers lower gain. ➨It has higher level of cross polarization radiation. ➨It has lower power handling capability.
What is a Duroid?
Traditionally locally available shingles were referred to as “duroid” shingles. The distinguishing characteristic of a duroid shingle is that they are manufactured using an or. ganic fibrous mat, most often recycled paper, as a foundation which is then impregnated with asphalt.
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 standard FR4?
FR4 is a standard defined by the NEMA (National Electrical Manufacturers Association) for a glass-reinforced epoxy resin laminate. FR stands for “flame retardant” and indicates that the material is compliant with the UL94V-0 standard on plastic material inflammability.
What is a microstrip antenna used for?
Microstrip antennae are also used in the fields of RFID (radio frequency identification), mobile communication and healthcare. Basically, an RFID system consists of a tag and a reader. Generally, it uses frequencies between 30 Hz and 5.8 GHz. In telemedicine application, microstrip antennae operate at 2.45 GHz.
What is advantage of microstrip antenna?
Compared with conventional antennas, microstrip patch antennas have more advantages and better prospects. They are lighter in weight, low volume, low cost, low profile, smaller in dimension and ease of fabrication and conformity.
What are Duroid shingles?
What is the difference between FR4 material and Rogers material?
The difference between FR-4 material and Rogers material Comparing to FR-4 material, Rogers material is great with high frequencies. 3. FR-4 material has a high Df or dissipation factor than Rogers material, suffering more signal loss.
What are RT/Duroid 5880lz laminates?
Rogers RT/duroid 5880LZ laminates are filled PTFE composites designed for exacting strip-line and micro-strip circuit applications. RT/duroid 5880LZ laminates contain a unique filler that results in a low density, lightweight material for high performance and weight sensitive applications.
Why use RT/Duroid 5870/5880 laminates for Ku-band applications?
Its low dissipation factor extends the usefulness of RT/duroid 5870 and 5880 laminates to Ku-band and above. RT/duroid 5870 and 5880 laminates are easily cut, sheared and machined to shape. They are resistant to all solvents and reagents, hot or cold, normally used in etching printed circuits or in plating edges and holes.
What is the dielectric constant of RT/Duroid 5870 laminates?
The randomly oriented microfi bers result in exceptional dielectric constant uniformity. The dielectric constant of RT/duroid 5870 and 5880 laminates is uniform from panel to panel and is constant over a wide frequency range. Its low dissipation factor extends the usefulness of RT/duroid 5870 and 5880 laminates to Ku-band and above.
