    摘要： Microwave distribution network, comprising a stacking of several layers (4), each of the layers (4) comprising a plurality of unit cells (1), wherein:
    - the unit cells (1) comprise a coaxial input (2) connected to three transmission lines (3) with an angular span of 120º, the coaxial input (2) being orientated on an Z-axis of a Cartesian system of axes in which the three transmission lines (3) are on an XY plane,
    - the layers (4) are configured as a hexagonal lattice formed with the unit cells (1) by periodical replication, with the coaxial inputs (2) placed at the corners of the hexagons, such that each unit cell (1) is connected to three neighbour unit cells, the coaxial inputs (2) of the three neighbour unit cells being oriented on an Z-axis of a Cartesian system of axes in which the three transmission lines (3) are on an XY plane, such that this orientation on the Z-axis is opposite to the orientation of the coaxial input (2) of the former unit cell (1) on the same Z-axis,
    - the distance between coaxial inputs (2) is such that it satisfies ¼ of the wavelength conditions, and
    - the adjacent layers (4) are interconnected by means of the coaxial inputs (2) of the unit cells that are arranged in opposite directions.

    摘要： A radar module (100; 200) comprises a low temperature co-fired ceramic, LTCC, substrate (101; 201), with a radar chip (102; 202) attached to a first surface (101a; 201a) of the LTCC substrate (101; 201) and a transmitting antenna (105, 106) for transmitting the radar signal attached to a second surface (101b; 201b) of the LTCC substrate (101; 201). The radar chip (102; 202) is configured to generate a radar signal for transmission. The transmitting antenna (105, 106) is configured to communicate with the radar chip (102; 202) through the LTCC substrate (101; 201). The radar module (100; 200) further comprises a beam steering element (205) configured to introduce a phase delay to the radar signal in order to adjust a first component of a direction of transmission of the radar signal.

    摘要： A RF distribution network for split beam antennas is disclosed. The split beam antennas may include four-column cross-polarized user specific tilt antennas implemented in a 4T4R or 4T8R system. A RF distribution network may provide transmit signals from transmitters to antennas while also providing receive signals from the antennas. A RF distribution network may include 180° 6.9 dB combiners coupled to the antennas and also coupled 90° hybrids. A 180° 6.9 dB combiner may include a transmission network with transmission lines in a 4T4R system. Alternatively, a 180° 6.9 dB combiner may include a transmission network with transmit and receive filters in a 4T8R system. The transmission network couples the transmit filter and two filters by at least three λ/4 transmission lines. A transmission network provides isolation between two receive signal paths and, at the same time, provides power splitting of transmitter power to two duplexed transmit signal paths.
