Latest Patents

One of Sultan’s patents describes a ferrite-loaded Fabry–Perot cavity antenna designed for beam scanning and shaping. Three magnetized ferrite cylinders are positioned within the cavity, and an externally controlled magnetic field enables beam steering. A composite dielectric superstrate helps reduce sidelobe levels as the scan angle increases. The 10 GHz antenna measures 6.4 × 2 × 1.6 cm and provides a 525 MHz impedance bandwidth at −10 dB, a directivity of 11.04 dB, and a broadside beam-steering range of ±12° under changes in the applied magnetic field.

Another patent concerns a wireless sensor network with energy-efficient protocols. The system connects external sensors to a data sink and combines a modified S-MAC medium-access-control protocol with a routing protocol based on cluster-head rotation. The approach is intended to reduce energy consumption by network nodes and their associated sensors.
