Dynamic Polarization Caveat • Must Compare to radiative field in time-domain HFSS CRES Time-Avg Loop Antenna (Magnetic Dipole) CRES Tx
Turnstile Produces Full Pattern Turnstile
Turnstile Turnstile • Generates full field • Requires 4 single-ended signals • Ferrous Tubes enhance magnetic dipole radiative moment Time-Avg CRES 2-differential modes, in quadrature
