    Research output: Contribution to journalConference articlepeer-review


    The Three-Dimensional Frequency-Independent Phased-Array (3D-FIPA) developed by Penn State provides low grating lobes, low sidelobe levels, nearly constant gain, beamwidth and impedance with a low voltage standing wave ratio (VSWR) over extremely large bandwidths. By using the full array, the physical volume can be built for high frequency (HF) through the microwave regions and its use can also be maximized. 3D-FIPA uniquely applies the log-periodic principle to form multi-layer dipole arrays that maintain all electrical spacings and heights over a user-specified frequency range.
