Optically transparent dual-band frequency-selective surfaces (FSSs) are promising candidates to address the specific design challenges of the Internet of Things. This paper demonstrates their potential by discussing different configurations of the two single-layer FSS designs on an innovative optically transparent polyvinyl chloride surface material. First, FSS cells consist of two cross dipoles placed forming angles of (Formula presented.), where each rotated dipole structure parallel to the other. Then, in the second design, each one of the two cells is mirrored to enable polarization control for each band. As a proof-of-concept, five prototypes of each design having a unit cell size of (Formula presented.) are fabricated through a combination of cost-effective printing and shearing. The manufactured prototypes yield more than 93% transparency and robust dual-band performance. Moreover, more than 20 and 40 dB isolation for lower- and upper-frequency bands are achieved from the fabricated prototypes. High-transparency, cost-effectiveness, and robust high performance in terms of suppression make both structures suitable for sub-6-GHz fifth generation applications.
