Patent number: 9912077Abstract: This disclosure is directed to broadband polarization diversity antennas. In one aspect, a polarization diversity antenna includes a baseboard with a baseboard-feed line located on a first surface. The baseboard-feed line includes a serpentine meander-line portion. The antenna also includes an antenna-array board with two or more antenna elements arranged in a series. The antenna-array board is attached to the first surface with the serpentine meander-line portion located between an edge of the antenna-array board and the baseboard. Each antenna element is connected to the serpentine meander-line portion via an antenna-feed line located on the antenna-array board. The antenna array provides two dimensional polarization broadcasting and receiving of electromagnetic radiation. In another aspect, a notch antenna is formed on an opposing second surface of the baseboard opposite the antenna-array board in order to provide three-dimensional polarization broadcasting and receiver of electromagnetic radiation.Type: GrantFiled: April 30, 2014Date of Patent: March 6, 2018Assignee: WavCatcher, Inc.Inventor: Sheng Yeng Peng

Publication number: 20170365928Abstract: This disclosure is directed to a broadband notch radiator antenna. In one aspect, a broadband notch radiator antenna includes a dielectric substrate having a first surface and a second surface. A conductive material is disposed on the first surface to form a horn-shaped dielectric notch antenna. The conductive material disposed on the first surface includes a meander line antenna connected to an edge of the horn-shaped notch. One or more microstrip feed lines and one or more inductance matching circuits are disposed on the second surface. The one or more inductance matching circuits are connected to the one or more feed lines.Type: ApplicationFiled: March 31, 2017Publication date: December 21, 2017Applicant: WavCatcher, Inc.Inventors: Sheng Yeng Peng, Ronald Westberg, Peter Y.

Patent number: 9761952Abstract: This disclosure is directed to broadband notch antennas. In one aspect, a notch antenna includes a dielectric plate having a first surface and a second surface located opposite the first surface. A conductive layer is disposed on the first surface and has a notch region that exposes the dielectric plate between edges of the conductive layer. The antenna also includes two or more frequency matching circuits that branch from the notch region. Each matching circuit is configured to send and receive electromagnetic radiation in a frequency band of a radio spectrum.Type: GrantFiled: October 25, 2016Date of Patent: September 12, 2017Assignee: WavCatcherInventor: Sheng Yeng Peng
