Modern wireless communication systems prefer higher frequencies to meet the growing demand for faster data transfer. The ...

This paper presents a low-profile, tightly coupled dipole array (TCDA) antenna to achieve broad-angle scanning with excellent impedance matching over a wide bandwidth. The antenna element is ...

Abstract: This brief proposes a temperature-compensated Ku-band eight-element four-beam phased-array receiver with low attenuation and relative phase variations. By properly adjusting the gate voltage ...

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 ...

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 ...

5G and future cellular networks intend to incorporate low earth orbit (LEO) satellite communication systems (SatCom) to solve the coverage and availability problems that cannot be addressed by ...

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.
