Abstract

It’s examined 2-D structures, representative by a cylindrical Dielectric Resonator (DR) system, situated on the planar metal surface around active irradiator, coupled with microwave line. Every DR becomes excited on it lowest resonance , and all structure as a whole are passive reflecting system, forming directional diagram of active radiation source. It’s demonstrated, that similar structures may effectively sharpen a directional diagram of antennas. On the basis an approximate solution of Maxwell equations has been developed antenna model. The basic antenna parameters – the radiation pattern, DR amplitudes and reflection coefficient, has been calculated. It’s investigated a possibility of working frequency band widening with improvement of radiation pattern.
