Abstract :
The novel concept of filter-lens array (FLA) is introduced in this paper. Measured results for a Ka-band design show that a typical FLA can meet system requirements for a wide range of applications. FLAs present a compact and simple means of focusing and filtering at millimeter-wave frequencies, and can replace the standard combinations of dielectric lenses and bandpass filters. They are expected to find application in power combining, medium-angle beam-steering, and millimeter-wave (mm-wave) imaging systems.
