As phased arrays begin to include more mixed-signal and digital content, there are many engineers who could benefit from a much more intuitive explanation of phased array antenna patterns. As it turns ...

This makes sense as the beam angle changes through a difference in phase across the array. Note that the peak of this characteristic is θRES, as previously calculated. Figure 4. Beam angle vs. number ...

Test fixtures are becoming more important in 5G, 6G, and phased-array designs. This article explains methods to optimize test ...

OPAs are an emerging technology made of arrays of closely spaced (around 1µm) optical antennas and which radiate coherent light in a broad angular range. l. The produced interference pattern can then ...

Our signal’s carrier frequency is 100 MHz, and the receiver is a uniform linear array (ULA) with 10 elements spaced by half wavelength. The signal source is 45 degrees of the array boresight.
