Tight batch-to-batch tolerance
• Wide Dk range from 2.6 up to 23
• Lower weight and better impact resistance
than ceramics
• Isotropic material suits well for
narrow beam widths (less than 0.2°)
• Injection molding for complex shapes
• Low cost mass manufacturing
Whether we are talking about portable satellite terminals or
stationary land stations, the material requirements are alike:
reliable, low loss materials with low manufacturing costs, light
weight and the ability to form complex shapes.
Feasible form factors can be obtained even
below 1 GHz with high permittivity materials.
