The concepts of phase shifting antenna elements to create a high-gain antenna can be extended to allow digital control of the antenna direction in what is known as an Electronically Scanned Antenna. Electronically scanned antenna arrays use phase shifting elements to...
Directional, high-gain antennas can be made using arrays of individual elements rather than through large horn or parabolic antennas. Individual radiating elements with controlled phase shifts combine to create more gain in a desired direction. Initially arrays of...
This video below discusses an individual antenna element, an array (e.g. leaky waveguide, PESA, AESA). What role does phase shift play in a system and the idea that relative distance and element size is related to frequency. We encourage you to pass this video along...
Understanding frequency selective services requires specific domain knowledge. This video provides an overview of filtering basics beyond just know if your filter is low-pass, band-pass, high-pass, or notch. How quickly does it roll off? How far into the stop band...
What is an FPGA device? A Gate Array is a prefabricated semiconductor device, like a silicon chip, that has not been configured to have a particular function during fabrication. The Field-Programmable Gate Array, or FPGA, is an integrated circuit that can be...
