Latest Patents

Pietro Ventresca's latest patents showcase cutting-edge developments in seeker technology. His first patent is for a **Dual Mode Seeker**, which is suitable for use in anti-radiation missiles. This device incorporates both an infrared sensor responsive to radiation within the 4.0 to 4.8 micron band and a radio frequency sensor that detects signals within the 6.5 to 16.5 GHz band. The infrared sensor is designed with a folded Cassegrainian telescope arrangement, utilizing a primary mirror that remains transparent to radio frequency energy. Meanwhile, the radio frequency sensor utilizes an annular array of orthogonally disposed stripline flared notch radiating elements, paired with a broadband microwave receiver that processes radio frequency monopulse signals effectively.

His second patent pertains to a **Phase Shifter and Polarization Switch**. This device features multiple serially coupled phase bits, allowing for a four-bit phase shifter and a polarization switch that can select from six separate polarization senses. Crafted within a stripline package, it employs hybrid couplers with output ports that connect to switchable reactances. The use of packaged microwave P-I-N or N-I-P diodes as switchable reactances further enhances the innovation, complete with a bias voltage supply sourced from an octave band choke.
