Patent number: 11611145Abstract: An antenna structure includes an asymmetric antenna, an antenna feed and a ground plane connected to the asymmetric antenna via the antenna feed. The ground plane includes radials which radiate from the antenna feed. Each of the radials includes: a first conductive element having a first end and a second end, the first end being conductively connected to the antenna feed, a second conductive element conductively unconnected to the first conductive element and to the antenna feed, and a resistor connecting the second end of the first conductive element to the second conductive element.Type: GrantFiled: January 28, 2021Date of Patent: March 21, 2023Assignee: Infinidome Ltd.Inventor: Moshe Kaplan

Publication number: 20230067684Abstract: An interference detector for detecting interference in Global Navigation Satellite System (GNSS) includes an RF splitter, multiple detectors and a comparator. RF splitter, splits a radio frequency (RF) input signal into multiple RF output signals which are provided to respective detectors. Each of the detectors includes a bandpass filter and a peak detector. The bandpass filter filters the RF output signal into a respective GNSS frequency band and the peak detector detects the peak level of the filtered RF signal. The comparator analyzes the peak detector outputs and identifies whether interference is present in the GNSS frequency bands by comparing the peak levels to respective thresholds. Based on this analysis, the comparator outputs a signal that indicates the presence and absence of identified interference in the GNSS frequency bands.Type: ApplicationFiled: August 31, 2022Publication date: March 2, 2023Applicant: Infinidome Ltd.Inventor: Moshe KAPLAN

Publication number: 20220330040Abstract: An antenna null steerer in a wireless network determines the conformance of a radio frequency signal received by multiple antennas to the protocol of the wireless network. When the received radio frequency signal is conformant to the protocol, the current antenna pattern is maintained. When the received radio frequency signal is non-conformant to the protocol, nulls are iteratively generated in the antenna pattern until the RF signal becomes conformant to the protocol and/or the maximum number of nulls are present in the antenna pattern.Type: ApplicationFiled: March 30, 2022Publication date: October 13, 2022Applicant: Infinidome Ltd.Inventor: Moshe KAPLAN

Publication number: 20220329345Abstract: A null steering adjuster in a stationary wireless network identifies the presence or absence of a current set of phase differences in a dataset. The dataset includes legitimate sets of phase differences detected between radio frequency signals received by multiple antennas from respective legitimate sources. The current set of phase differences is detected between radio frequency signals currently received by the antennas. When the current set of phase differences is absent from the dataset, a null is created in the antenna pattern of the antennas in the direction of the currently-received radio frequency signals. When the current set of phase differences is present in the dataset, the antenna pattern is maintained.Type: ApplicationFiled: March 30, 2022Publication date: October 13, 2022Applicant: Infinidome Ltd.Inventor: Moshe KAPLAN
