How Does Starlink's Phased Array Antenna Track Satellites …
Nov 25, 2020 · How does a Starlink phased array antenna work? A Starlink phased array antenna uses a technique called beamforming to direct and focus the antenna's signal towards a specific satellite in space. This allows for a more efficient and reliable communication with the satellite. What is the purpose of a Starlink phased array antenna?
What Happens When Using Long-Wave Frequencies with Starlink …
Jan 3, 2021 · The antenna elements in a Starlink phased array are connected to a central controller, which can adjust the phase and amplitude of each element. This allows the antenna to steer its beam towards a specific satellite in space, enabling two-way communication between the ground station and the satellite.
Reflectivity metals at high frequency - Physics Forums
Jan 20, 2011 · The study of reflectivity in metals at high frequency has various applications, including in the design and optimization of antenna systems for communication and radar, as well as in the development of materials for shielding against electromagnetic interference.
Star like object travels in a zigzagging pattern relative to other stars
Jul 14, 2024 · I have a question that must have logical answer and I just cant find one online. Yesterday, around 11 P.M. me and my wife was sitting on our porch talking and casually watching the sky. Suddenly, our attention was caught by a star like object that was traveling towards east. Speed was like any...
Why can't diffraction happen if wavelength>slit size - Physics …
Jul 1, 2015 · In contrast, an EM wave with a frequency much too low for the antenna would essentially not 'see' the antenna at all. The shielding in your microwave's door also does this. Its physical surface area is much less than a solid piece of metal would be for the same size, but the microwaves act as if the shielding is a single, solid object without ...
Two radio antennae radiating in phase - Physics Forums
May 8, 2005 · Two radio antennas A and B radiate in phase. Antenna B is a distance of X meters to the right of antenna A. Consider point Q along the extension of the line connecting the antennas, a horizontal distance of Y meters to the right of antenna B. The frequency, and hence the wavelength, of the emitted waves can be varied.
Orientation of Electric Fields in a Bucking Coil Setup - Physics …
Oct 18, 2021 · For lumped elements like that, the E-field does not enter into the functional analysis. You are only concerned with the currents and the magnetic flux produced by them. You do not need to try to analyze this lumped component like it's an antenna. If you start talking about GHz circuit analysis, that is a different topic, and much more complicated.
Electric Field Produced by a Finite Charged Wire - Physics Forums
Jun 7, 2017 · In summary, we can use the constant k=1/4πϵ0 and the variables L, λ, and d to find the magnitude E of the electric field at point P, a distance d above the midpoint of a charged wire with length 2L units and linear charge density λ.
Frequency Modulation (FM) Tutorial Lawrence Der, Ph.D. Silicon Laboratories Inc. Introduction Edwin H. Armstrong, known as one of the founding fathers of radio technology, invented the
Can You Get Shocked Without Being Grounded? - Physics Forums
Nov 4, 2012 · Consider the person to be similar to an antenna connected to an 500,000 to 700,000 volt AC power source, there is current flowing through an "antenna" as the AC voltage at the powered end of the "antenna" cycles back and forth.
