Latest Patents

One of his latest patents is the "Transreflector antenna for wireless communication system." This invention features a compact and lightweight antenna designed for receiving microwave direct line of sight wireless data signals, particularly useful in services such as Local Multipoint Distribution Services (LMDS). The antenna is engineered to provide precise control over the isolation of polarized signals. It consists of an external parabolically shaped dome made from a resilient material like thermoplastic. The interior surface of the dome has a polarizing conductive grating that acts as a transreflector for vertically polarized radiation. A twist reflector along the axis of the conductive grating reflects the received radiation back towards the transreflector with a different polarization. The energy is then reflected by the conductive grating at a feed point located at the center of the twist plate. The manufacturing process of the transreflecting element involves using a substrate that has been printed and etched or a nonconductive substrate that has been silk screened with conductive ink.

Another significant patent is the "Device for propagating radio frequency signals in planar circuits." This device allows for the efficient propagation of radio frequency (RF) signals, enabling the concurrent transmission of signals with different polarizations. It includes a waveguide with an input port for receiving electromagnetic radiation with first and second polarized signals that are orthogonal to each other. The waveguide contains first and second substrates that are substantially transmissive of the electromagnetic radiation. Each substrate has a probe for transmitting or receiving its respective polarized signal. Additionally, a grid substrate is mounted within the waveguide, featuring a multiplicity of metallic lines that are reflective of the first polarized signal while being transmissive of the second.
