With a total of 5 patents to his name, Chivukula's work is recognized for its innovative approaches to antenna design and functionality.

Latest Patents

One of his latest patents is focused on achieving high isolation between transmit and receive antennas in FMCW radars. This invention involves a radar antenna that provides isolation between the transmit (Tx) and receive (Rx) antennas through the arrangement of their elements. The transmit antenna elements are orthogonally fed compared to the receive antenna elements, which enhances performance. For instance, horizontally polarized receive antenna elements can be paired with vertically polarized transmit elements, leading to improved signal integrity. Additionally, a low insertion loss 90-degree polarizer layer is incorporated to ensure that the reflected signals match the polarization of the receiver antenna.

Another notable patent is for a dual band phased array antenna structure. This dual band antenna features a first radiating element operating in a first frequency band and a second radiating element in a second frequency band. The design includes a ground plane with slots associated with each radiating element, along with dedicated feed probes for optimal performance. This innovative configuration allows for enhanced functionality across multiple frequency bands.
