Rogers RO4533 properties:

Because to its excellent mechanical, thermal, and electrical properties, RO4533 laminates are helpful in a variety of applications. Following are some of these characteristics;

Low dielectric constant: The dielectric constant assesses a material's capacity to store energy in an electric field. At 10GHz and 23°C, Rogers RO4533 has a dielectric constant of 3.3. In the market for antennas, a low dielectric constant material is preferred. When subjected to strong electric fields, materials with low dielectric constants resist degradation.

Good Thermal Expansion Coefficient: In the X and Y axes, this material's thermal expansion coefficient is evaluated at 13 and 11 ppm/°C, respectively. A PCB material's CTE specifies how it expands in reaction to a temperature change. Because Rogers RO4533 has a low CTE, it can likely be used in any temperature range.

High thermal conductivity:The ability of a printed circuit board material to transfer heat is gauged by thermal conductivity. Rogers RO4533 has a thermal conductivity of 0.6 W/m/K. The need for laminates suitable for antennas is met by this thermal property.

Low rate of moisture absorption: Rogers RO4533 laminates extremely slowly absorb moisture. It absorbs moisture at a rate of 0.02%. A humid climate won't harm these laminates. PCB materials typically absorb less moisture than 0.2% at a time.

Dissipation factor: The Rogers 4533 has a dissipation value of 0.0025 at 10GHz and 23°C. This metric displays the rate of energy loss brought on by a material's inborn characteristics. Due to their low dissipation factor, these laminates have an effective insulator system.

Rogers Ro4533 is a product with exceptional dimensional stability, whose dimensional stability is less than 0.2mm/m. This demonstrates that this material's size is unaffected by exposure to high temperatures.

Rogers 4533's advantages:

The electrical and thermo-mechanical properties required by antenna designers are provided by Rogers RO4533 laminates. For users, these laminates have many advantages.

An affordable choice : A practical choice for antenna designers is the Rogers RO4533. With it, designers can maximize the performance of their antennas, making it a superior substitute for PTFE antenna technologies.
