Abstract Ever since Germany's use of chlorine gas on the battlefields of Flanders during the First World War, modern warfare has become synonymous with gas warfare, its images an iconographic shorthand for a detached, humiliating, and dishonourable d

This paper presents the design and implementation of power amplifiers using high-power gallium nitride (GaN) high electronic mobility transistor (HEMT) powerbars and monolithic microwave integrated circuits (MMICs). The first amplifier is a class AB

The non-radiative dielectric (NRD) waveguide is used for the first time as a dual mode waveguide. The LSE/sub 01/ and LSM/sub 01/ modes are excited independently via a novel microstrip to NRD waveguide dual mode transition. The transition is connecte

Large planar antenna arrays typically suffer from increasing loss due to a planar feed network. A solution to this problem is the application of lower loss feed networks. This contribution evaluates nonradiative dielectric (NRD) guides as transmissio

A major restriction of high gain microstrip antenna arrays is found in their high losses, mainly due to the feeding network. In this contribution, design and results of a 24GHz microstrip array antenna with low loss, low cost and low profile NRD-guid
