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 ...

Autocorrelation matching method is proposed for phase-only synthesis of power pattern of linear antenna arrays. This method is based on equating the autocorrelation coefficients of an array having ...

Smart antennas have been considered as a key technology to provide the services demanded by mobile network users. This article presents the radiation pattern obtained for a linear antenna system ...

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 ...

The focus then turns to the array factor, GA. The array factor is calculated based on array geometry (d for our uniform linear array) and beam weights (amplitude and phase). Deriving the array factor ...

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. This ...

Part 1 of the series covered beam direction and working with a uniformly spaced linear array of antennas. In part 2, we’ll cover antenna gain, directivity, and aperture, as well as array factors.
