    Design Antenna LNA Loppunut left

    I am looking for a skilled engineer to design an antenna LNA for my project. The antenna needs to cover the MHz frequency range. The desired gain for the LNA is 48dB, with a noise figure of less than 1.5dB. The bandwidth should be between 1550-1620MHz. The size of the antenna should be 50*50mm. Deliverables: Provide all design files. Diagram, Simulation files, Schematic and PCB files, Gerber & BOM files. Requirements: 1. There is a hole via for the feed pin in the center of the LNA board for the GNSS patch antenna. The hole via is the input of the LNA board, and the output is the solder pad connected to the RF coaxial cable. 2. Since the LNA consumes power, RF signals and DC 3.3V are transmitted together through the coaxial cable. So the LN...

    Antenna Design: Start with a well-designed PCB antenna layout. Common designs for BLE antennas include meandered monopoles or inverted F-antennas. The design should be based on the desired operating frequency (usually around 2.4 GHz for BLE) and the available PCB Dimensions: Ensure that the physical dimensions of the antenna (length, width, and spacing) match the design specifications, which are typically calculated based on the wavelength at the operating Plane: Maintain a good ground plane beneath the antenna. A solid ground plane helps with the antenna's radiation pattern and impedance Matching: Use a network analyzer or an impedance matching network (like a matching circuit) to adjust the antenna's impedance to match the des...

Finally, could also use netflow/sflow to record the connections made from each internal IP.] 2) The setup has to be and have OSFP at the PtPs so if one PtP fails the internet to go through the other antenna. 3) The Edgerouter will have 2 lines so it will be one main line and one as Failover line 4) It is neede to setup Wireguard VPN tunel to the key given. 5) make all the setups and the packages at the UISP Cloud at the setup there will be a Tiny pc connected that can have windows or linux in order to make the logging and to have remote access to the network.

    Results shall be used for an analysis of how much coupling effects between VHF/UHF antenna to ground can be suppressed or even avoided by covering the ground surface under the antenna with absorbing ferrite tiles. The antenna is a quadfilar helix antenna being circular polarised and pointing vertically to the sky. The CEM simulations shall consider several distances under the antenna to the ground or to ferrite tiles of a few centimetres to several meters. Whereas the size of the surface of the required ferrite tiles shall be kept minimal but reaching moderate or good agreement with antenna pattern in free space / without ground.
