This is the second article of our three-part series on phased array antenna patterns. In Part 1, we introduced the phased array steering concept and looked at the influencers on array gain. In Part 2, ...

Figure 1. Vertical radiation pattern on a 12-level antenna. Click here to see an enlarged diagram. This issue is illustrated in Figure 1, which shows typical VRPs in a complex array that uses both ...

A pattern reconfigurable antenna array is proposed for the purpose of improving spatial coverage at millimeter-wave frequencies. An endfire magnetoelectric (ME) dipole and two slot-patches with ...

Southwest Research Institute (SwRI) is expanding its antenna measurement capabilities with a state-of-the-art spherical ...

ArRaydiate ArRaydiate is an interactive program in JavaScript to aid in understanding radiation patterns of antenna arrays. It produces a 2D visualization of a radiation pattern for a linear antenna ...

Antenna array pattern synthesis is finding weights of amplitude and phase of every array elements to satisfy a set of specifications on the beam pattern. The global synthesis of antenna arrays that ...

Dregelyet al. fabricate an array of 3D optical Yagi–Uda nanoantennas and show that radiofrequency antenna array concepts applied to the optical regime can provide improved directional properties.

The electronic steerable parasitic array radiator (ESPAR) antenna consists of a single-fed shorted patch surrounded by four rectangular parasitic elements. The antenna system can develop four ...
