Abstract: The impact of the array factor (AF) on the synthesis of a low-sidelobe taper for planar array antennas with a periodic element grid is investigated. A low-sidelobe taper that is synthesized ...

This paper presents the optimization performance of non-uniform linear antenna array with optimized inter-element spacing and excitation amplitude using Particle Swarm Optimization (PSO). The aim of ...

6G is expected to bring data speeds that enable highly integrated and responsive technology in smartphones, homes, cities, and autonomous vehicles, but realizing that goal will require a lot more work ...

Abstract: A general approach to determination of geometrical parameters of planar array antennas designed for forming of orthogonal beams steered in the nodes of a Cartesian periodic lattice specified ...

Kymeta’s new multiband KuKa antenna promises the ability for autonomous military systems to seamlessly switch from one satellite network to another to avoid jamming. (Photo courtesy of Kymeta) ...

The digital correlator is one of the most crucial data processing components of a radio telescope array. With the scale of radio interferometeric array growing, many efforts have been devoted to ...

As phased arrays begin to include more mixed-signal and digital content, many engineers can benefit from a more intuitive explanation of phased-array antenna patterns. It turns out that many analogies ...

If you think antennas must live “outside” a circuit, think again: they can also be housed in a small package adjacent to the active components they serve. The previous part established the context and ...

Beamwidth provides a metric of angular resolution for antennas. Most commonly, beamwidth is defined by either the half-power beamwidth (HPBW) or the null-to-null spacing of the main lobe (FNBW). To ...

EMC antennas are an important component for capturing radiated harmonic emissions from products being tested. There are two considerations: simple troubleshooting or calibrated pre-compliance testing.

This article appeared in Microwaves & RF and has been published here with permission. When studying 5G NR operation, it’s not immediately obvious that 5G meets all of the objectives of the 3GPP ...
