RESUMO

The radar scatter cross-section is calculated for a cylindrical microstrip antenna with a novel strip loop radiator with a slot. The resonance properties of a solitary and coupled strip loop radiators with slots are analyzed. Amplitude and phase distributions of the surface current density across the radiators are calculated. It is shown that the resonance frequencies of the suggested strip loop radiators with a slot are shifted considerably toward lower frequency range as compared with the characteristic frequencies of radiators of the cylindrical-rectangular geometry. It is shown that radiators of the kind may prove prospective for application in small-size microstrip antennas, including those operating at shorter wavelengths.
