RLD^™ creates lens designs based on typical input parameters. An extensive range of output values may be displayed for a given design. Some of the main input and output parameters are listed below.

Inputs

• Type of Lens - microstrip or stripline
• Impedance of lines
• Element spacing on the antenna
• Number of Elements (up to 64)
• Number of beams (up to 64).
• Maximum scan angle.
• Off-Axis Focii Angle as a fraction of Max Scan Angle
• Bandwidth and Center Frequency
• Electrical characteristics of lens material - dielectric constant, loss tangent, conductivity and thickness of dielectric material.
• Electrical characteristics of absorber material
• Physical characteristics of lens - Focal Length/Diameter Ratio
• Aperture distribution
• Port flare angles

Outputs

• Calculation of the lens contour and of the transmission line geometry
• Element locations along the lens contour
• Insertion loss (per beam port)
• Amplitude and phase distributions of the array ports versus frequency.
