In the recent research on cylindrical monopole plasma antenna excited by surface wave, many meaningful results about plasmas antenna, e.g. the analysis of physical characteristics, numerical calculation methods, software simulation, diagnosis of parameters have been obtained. But the precise model of monopole plasma antenna according to its three-dimensional structure has not been proposed yet....

A novel dielectric embedded electronically steerable passive array radiator (ESPAR) (DE-ESPAR) antenna array for mobile wireless communication terminal is developed by finite element method based numerical modeling technique. The size reduction of the seven-element monopole antenna was accomplished by embedding the array in a cylindrical rod of FIK ceramic complex with a relative permittivity a...

A new V-shaped slot antenna built on a dielectric substrate is presented. The antenna is a non-resonant, travelling-wave design, with a predicted impedance in the range from 50R t o €400. Calculations indicate that this antenna should have a gain of 15 dB with 3-dB beamwidths of loo in the H plane and 134' in the E plane. Pattern measurements at QOGHz support the theory. It should be possible t...
