  • Patent number: 11888228
    Abstract: A microwave prism is used to repoint an operational Direct-to-Home (DTH) or Very Small Aperture Terminal (VSAT) reflector antenna as part of a ground terminal to receive (or transmit) signals from a different satellite or orbital position without physically moving the reflector or the feed horn antenna. The microwave prism operates by shifting the radiated fields from the horn antenna generally perpendicular to the focal axis of the parabolic reflector in order to cause the main beam of the reflector to scan in response. For an existing reflector antenna receiving signals from an incumbent satellite, a prism has been designed to be snapped into place over the feed horn and shift the fields laterally by a calibrated distance. The structure of the prism is designed to be positioned and oriented correctly without the use of skilled labor.

    Abstract: An electronic device that communicates a packet or a frame is described. This electronic device includes: at least an antenna having an antenna radiation pattern; an interface circuit; and an antenna cover that includes an integrated static lens, where the antenna cover is selected from a set of antenna covers that includes different integrated static lenses. During operation, the interface circuit may transmit, from the antenna, wireless signals corresponding to the packet or the frame, where the integrated static lens modifies the antenna radiation pattern of the antenna. For example, the integrated static lens may cause the wireless signals to converge or diverge. Alternatively, the integrated static lens may change an angular elevation of the antenna radiation pattern and/or may provide a correction for pathloss as a function of angle. Note that the integrated static lens may be a stepwise approximation to a predefined function.

  • Patent number: 11509042
    Abstract: A novel and useful radome suitable for use in an automotive radar system that employs patch antenna arrays. In one embodiment, the radome is a ‘U’ shaped half cylinder for patch antenna arrays such as on a printed circuit board (PCB). The patch antennas may or may not be situated in the same plane. Each array has its own half cylinder associated with it. Each array may have a different antenna pattern with different gain and side lobes. In this case, each patch antenna array has its own radome configured appropriately. Alternatively, the radome comprises a half sphere shape (or bubble shape) whereby each antenna port has its own individual half sphere shaped radome. This functions to improve the performance of the radome by increasing the number of curved dimensions from one to two.

  • Patent number: 11489265
    Abstract: The present invention discloses a reconfigurable wideband phase-switched screen (PSS) based on an artificial magnetic conductor (AMC). Gap capacitance between patches is controlled by changing the capacitance of varactors, so that periodic units have a plurality of continuous frequency points. A phase difference between two adjacent frequency bands is 143°-217°, so that the periodic structure absorbs incident electromagnetic waves in a wide frequency band, and the broadband PSS is implemented with a relative bandwidth of 45.2%. The AMC structure according to the present invention is simple in structure and easy to process, with a thickness less than one twentieth of the working wavelength, and greatly reduces size and costs.

  • Patent number: 11469503
    Abstract: An antenna system including one or more a frequency responsive components (FRCs) may employ filters to one or more paths in the antenna system corresponding one or more radiating elements on those paths. The FRCs can block a signal from reaching the radiating elements effectively causing the radiating elements to become non-contributing to the antenna systems radiating pattern performance, and thus, maintain a consistent aperture value associated with the antenna system. In some cases, the FRCs may be configured to block a signal when the antenna system is operating at a particular frequency.

  • Patent number: 11329386
    Abstract: The invention comprises a device for receiving electromagnetic signal and radiating the signal further. With that device the signal can be repeated on the other side of a barrier, for example a wall, which prevents the signal to propagate. The receiving section (1) of the device has been made as a planar aperture antenna, as well as the re-radiating section (2). The above-mentioned planar aperture antenna has been made so that between the antenna parts of conductive material (6) there is an opening (7) which opens in the propagation direction of the signal (4 and 5). Between the above-mentioned receiving section (1) and the re-radiating section (2) there is a signal transmission section (3) which has been implemented as two parallel conductors (8) with a gap (9). The transitions between the receiving section (1), the signal transmission section (3) and the re-radiating section (2) have been realized in stepless manner without separate connectors.
