In this work, we demonstrate theoretically and experimentally a technique allowing us to realize a polarization-insensiti¨e wa¨elength con¨ersion with an output beam whose polarization state is unique and linear for all input signal polarization states. ᮊ ABSTRACT: A circularly polarized cylindrical dielectric resonance antenna excited by two conformal strips of unequal lengths is studied experimentally. By using unequal strip lengths, two nearly degenerate orthogonal modes are excited and circularly polarized fields are generated. The measured return loss, axial ratio, radiation pattern, and antenna gain of the configuration are discussed. ᮊ
