The unique properties of NorCLAD make it perfectly suited for use in microstrip patch antenna designs. NorCLAD has a low dielectric constant and low dissipation factor and good thermal performance that make it an excellent choice for GPS receiver and WLAN router antennas. It is an isotropic material that gives it excellent Dk tolerance control for improved center frequency performance. The material is available up to 0.500 in. thick for bandwidth considerations. NorCLAD is frequently used in stacked microstrip patch antenna applications. Available thicknesses range from 0.060 to 0.500 in. and in 20 in. x 22 in. panels. Available copper weight per thickness ranges from 0.5 to 2.0 oz./ft2.
Important properties of NorCLAD include:
- Dielectric constant of 2.55
- Dissipation factor of 0.0011 at 3 GHz
- Operating temperature range of -55° C to +125° C
