Peter Delos, Technical Lead, Bob Broughton, Director of Engineering and Jon Kraft, Senior Staff Field Applications Engineer, all with Analog Devices. With the proliferation of digital phased arrays in ...

In Part 1, we introduced the phased array concept, beam steering and array gain. In Part 2, we presented the concept of grating lobes and beam squint. In this section, we begin with a discussion of ...

In this article, I will cover various aspects of millimeter wave (mmW) beamforming and antenna technology with what I consider interesting and unique technical design examples. Beamforming networks ...

A novel technique is shown to improve the isolation between radiators in antenna arrays. The proposed technique suppresses the surface-wave propagation and reduces substrate loss thereby enhancing the ...

In this paper, we study Multiple slit diffraction and n- array linear antennae in negative refractive index material. We show that the evanescent wave plays a vital role in the near-field term. The ...
