He holds a total of 3 patents that showcase his innovative approach to solving complex engineering challenges. His work has significantly impacted the field of remote sensing and communication systems.

Latest Patents

One of his latest patents is the Ferrite-loaded, Fabry-Perot cavity antenna. This innovative antenna utilizes a novel superstrate-based beam scanning and shaping mechanism by optimally placing three magnetized ferrite cylinders within the cavity. The design allows for beam scanning in a specific direction, requiring oppositely located ferrite cylinders to be axially biased using an externally controlled DC magnetizing field. The antenna achieves a −10 dB impedance bandwidth of 525 MHz, a directivity of 11.04 dB, and a broadside beam steering range of ±12° for changes in the externally applied axial magnetizing field. The dimensions of this 10 GHz ferrite-loaded FPC antenna are 6.4 cm × 2 cm × 1.6 cm.

Another significant patent is the multifrequency antenna with reduced rear radiation and reception. This design comprises a stack of nonconductive, substantially planar substrates, each with a conductive layer on its surface. The first substrate includes transmission lines on its rear surface, while the second substrate is stacked on top, featuring a conducting layer on one side. The multifrequency antenna is enclosed with a lossy dielectric-magnetic material to prevent electromagnetic energy penetration, enhancing its performance.
