Patent number: 9899722Abstract: An antenna array configuration is provided with h-plane splitters between ends of a feeding network and radiating elements e.g. horns, thereby to reduce the distance between the centers of the horns to less than one wavelength which results in a better side lobe level. A method of manufacturing upper and lower plates together constituting an antenna is also provided, typically making each plate in a single operation, by dividing the feeding network's waveguides at the centre where there are no cross currents so as not to disturb propagation in the feeding network. The radiating elements, h-plane splitters and upper half of the feeding network may be fabricated in one plate without undercuts hence simplifying manufacture of the plate which may for example be formed using a simple molding machine or a 3 axis-CNC machine.Type: GrantFiled: January 14, 2016Date of Patent: February 20, 2018Assignee: MTI WIRELESS EDGE, LTD.Inventor: Israel Saraf

Patent number: 9859617Abstract: An antenna methodology where a set of antennas are formed that take the shape of a mobile wireless device and can be integrated into the outer housing of the mobile device. Tuning points are integrated into the design to provide the capability to compensate for hand effects and loading while the mobile device and antenna are touched by the user. The body then becomes a part of the antenna and acts as an anchor for the poles within the matching circuit. These antennas are actively tuned based on detection criteria while dynamically tracking system performance. The structure is based on a loaded loop coupled to an isolated magnetic dipole (IMD) element. The loop is actively tuned according to design rules residing in a processor in the mobile device.Type: GrantFiled: September 10, 2012Date of Patent: January 2, 2018Assignee: ETHERTRONICS, INC.Inventors: Laurent Desclos, Sung-Soo Nam, Ji-Chul Lee, Sung Hawan, Chun-Su Yoon
