Abstract: A novel approach is presented to design the dual-band planar sensor for the communication system. The proposed sensor is based on the complementary split ring resonator (CSRR) topology employing the cross-polarized excitation, which facilitates its operation even at the higher frequency band (28 GHz). The cross-polarized excitation of a CSRR allows efficient coupling of both electric and magnetic fields from the microstrip line, thereby producing the frequency-controlled dual resonance response. The prime focus here is to use the proposed approach to design two sensors with one sensor being simultaneously operated in the X-band and 5G band, while another sensor is operated in the 4G LTE band. The cross-polarized arrangement helps to achieve the higher dielectric sensitivity (17.21%) and Q factor (90) as compared to that of the co-polarized CSRR-loaded microstrip line sensor (14%, 73), where split of rings is aligned in the direction orthogonal to the microstrip line.
