The article describes a novel low‐loss microwave diplexer based on compact planar filtering
elements. These are composed of spiral resonators and etched directly onto the signal layer …

The feasibility of topological metawaveguides supporting helical propagation in the
microwave range has been recently proven. The advantages of unidirectional propagation …

This short contribution is dedicated to the Italian Vilfredo Pareto [Paris, France, July 15, 1848-
Celigny, Switzerland, August 19, 1923]. He was an engineer, an econo mist, and a …

The identify friend or foe antenna is a complement to many radar antennas which allows the
discrimination between friendly and hostile targets by receiving identification data. Such …

Two relatively novel optimization algorithms, the invasive weed optimization and the grey
wolf optimizer are here applied to the design of a lowpass microstrip filter to compare their …

A 2DOF vectored thruster mechanism was designed to provide an ROV with full spatial
mobility under minimum control forces. Some comparisons were developed based on …

A compact microstrip rat race attained by artificially shortening its lines by inserting stubs is
presented. The design starts with a preliminary theoretical length reduction where quarter …

The spectral and energy efficiency trade-off is a current issue in Massive MIMO (Multiple
Input, Multiple Output) systems. It creates a multi-objective problem that can be solved using …

Investigation on ultra-wide band slot-sinuous antenna for in band mono static radar cross
section behaviour are performed. The possibility of using opening ellipses on the metallic …

In this paper, an ultra-wide band modified slot-sinuous antenna has been designed to
enhance bistatic radar cross section (RCS) response. The design procedure consists of …
