Abstract Direction finding using a cylindrical array of dipoles has been implemented in presence of large cylindrical scatterers. A different number of scatterers in the simulations are used. The effect of the large cylindrical scatterers is consider

Abstract Three‐dimensional dipole arrays are normally used at the proximity of a reflective structure. Filamentary short‐circuited dipoles are proposed to model the effect of the reflector structure. The computational burden is significantly redu

A millimeter wave H-plane duplexer with E-plane filters has been designed. The channel filters are connected via a T-junction which is compensated by a cylindrical post and analyzed by integral contour method. Moreover, the junction discontinuity eff

A low-drift optoelectronic oscillator (OEO) is developed and experimentally shown. In the proposed OEO, a fiber Sagnac interferometer, including an optical phase modulator (PM) and a nonreciprocal bias unit, functions as an intrinsically drift-free i

Coupled oscillator arrays (COAs) can be used to control the phase distribution across the aperture of an array antenna in such a manner as to affect steering of the beam without the use of phase shifters. Given the various possible planar configurati

A novel substrateless power amplifier module realized by ridge gap waveguide (RGW) technology is proposed in Ka-band. Up to our knowledge, this is the first time that an active device is directly integrated with an RGW structure. No substrate is used

In this study, the authors investigate the effect of the random free-running frequency distribution of oscillators in two-dimensional (2D) coupled oscillator arrays (COAs) on the phase error of the elements, and consequently on the beam-pointing angl
