Title: The Innovations of Stelios Papatheodorou
Introduction
Stelios Papatheodorou is an accomplished inventor based in Morristown, NJ (US). He has made significant contributions to the field of antenna technology, holding a total of 2 patents. His work focuses on improving the efficiency and manufacturability of antennas, which are crucial components in modern communication systems.
Latest Patents
One of his latest patents is for a "Patch antenna using non-conductive frame." This innovative design utilizes a non-conductive frame to support the resonators in a patch antenna assembly. The frame avoids creating unwanted electric field polarizations by not making holes in the resonators. Additionally, it grasps the resonators in areas of low current density, minimizing disturbances in the radiation pattern. The design also includes posts for attaching the frames to the feedboard without the need for additional components like screws.
Another notable patent is the "Aperture-coupled planar inverted-F antenna." This antenna features a radiating patch on one side of a ground plane, separated by a dielectric material. A shorting strip connects the radiating patch to the ground plane at a dominant mode null, allowing for a reduction in the size of the radiating patch by a factor of two. The microstrip feedline is arranged on the opposite side of the ground plane, with signals coupled through an aperture. This method of aperture coupling not only reduces costs associated with conventional feeds but also enhances manufacturability and tuning flexibility.
