PROJECT TITLE :
Wide Angular Coverage Deflector: 60-GHz three-dimensional passive electromagnetic deflector achieves wide angular coverage.
A 3-dimensional (three-D) passive electromagnetic (EM) deflector configuration, based on the concept of spatial feeding, is proposed that modifies the incident EM energy from the steerable planar antenna array (source) to achieve wide angular coverage. A generalized analytical formulation of the parametric deflector configuration is dispensed. The analytical modeling has been validated by 3D simulations and measurements. The analytical results for the deflector configuration indicate that a wide angular coverage is possible at the value of reduced gain. An improved 60-GHz circularly polarized (CP) deflector element has been designed that provides part shift with component rotation upon transmission of circular polarization. The simulation results show that the proposed CP part operates successfully, in terms of realization of part-shift vary from zero? to 360? and sensible transmission properties (transmission loss < one dB) for the required frequency band of 57?64 GHz.
