  1. What does the term "boresight", and what do the phrases "boresight ...

    Aug 13, 2021 · For example, see this paper. However, I have not seen any explanation of what these actually mean. What does the term "boresight", and what do the phrases "boresight adjustment" or …

  2. rf - Which is the cause of "scan losses" in a linear phased antenna ...

    May 17, 2021 · This characteristic, called scan loss, follows 10*log (cosN (Ɵ)) power, where Ɵ is the scan angle off boresight and N is a numeric value, typically in the 1.3 range, which accounts for the …

  3. how to understand grating lobe problem in broadside array

    Mar 30, 2021 · In order to steer the array (maximize the gain) to an angle theta relative to boresight, you need to apply a phase shift between the two elements as is shown in the equation. A grating lobe …

  4. Finding out antenna gain in 3-D space (azimuth and elevation)

    May 11, 2019 · The diagram doesn't provide any information about how the gain varies as a function of azimuth, but for many analysis purposes with most patch antennas you can just assume the beam …

  5. rf - Received power from multiple transmitters - Electrical Engineering ...

    Mar 3, 2023 · Edit: some patterns - if the two transmitting antennas are half a wavelength apart, you get a max on boresight and a null on axis. So the 'extra' power you get at 90deg is at the expense of …

  6. polarity - Left and right circularly polarized antennas - which one to ...

    May 9, 2021 · The antennas should be wound in the same direction, which is to say they have opposite polarization, since polarization of an antenna is defined according to what you see when looking …

  7. phased array beam width spread as beam scans off boresite

    May 19, 2020 · What is the approximate phased array beam width spread as beam scans off bore site? Assume nominal scan space of 120 deg Azimuth by 90 deg Elevation, ie +/- 60 by +/- 45. Array …

  8. Distance of IR radiation - Electrical Engineering Stack Exchange

    Oct 6, 2018 · We moved the transmitter until aligned with the RX sensor both in boresight and angle-of-deflection; at 30 feet, outside in the sunlight, the RED LED would change state, indicating the …

  9. RF Output Power vs Antenna gain - Electrical Engineering Stack Exchange

    Aug 21, 2018 · I have a RF device which work on 2.4 GHz and Output power is 30 dBm (1 W), RF output is connected to a whip antenna (gain 2 dBi, omidirection), distance track between RF pad to …

  10. Antenna sector power ratio (total power) - Electrical Engineering Stack ...

    This is maybe a very basic question, which is driving me insane, because I can't remember the theory and neither I can seem to find any source about the topic. I have an antenna, whose SPR (sector
