Refined optimization of complex curve–linear-shaped radiators, such as traveling-wave Vivaldi antennas, can be achieved by considering simulated near fields to interpret in detail the structural influences a design. The relationships between space and time distributions electromagnetic (EM) energy clusters geometric features are revealed with appropriate use impulse response analysis combined m...

Abstract An increase of 7 GHz in the industrial, scientific and medical ISM band around 60 has opened it up for many modern wireless applications such as 5G. This means that new component designs can cater this large bandwidth are need hour. The design a bandwidth, completely planar high gain novel Vivaldi antenna is presented. Being travelling wave implemented using single metal layer make an ...
