Half truncated icosahedral passive electromagnetic deflector for the 60 GHz band

A possible low-cost alternative to a multifaceted active antenna array configuration for wide angular coverage is proposed. It consists of a single planar antenna array and a passive electromagnetic half truncated icosahedral deflector, comprising multiple facets with different deflecting behavior. A generalized formulation for the simple set-up of the proposed configuration is simulated in MATLAB and a comparison is made with CST MWS simulation. An important aspect of this configuration is the determination of the deflector´s transmission coefficient; the measurement shows an acceptable performance with a transmission loss of (0.63–1.5 dB) and (2.72–3.12 dB) for the 0° and 34° deflectors, respectively, in the 57–63 GHz frequency band.
