Abstract: This article presents the performance of a hexagonal split-ring resonator (H-SRR) antenna in the 2.4/5.2GHz bands and evaluation of channel capacity for single-input multiple-output (SIMO) and multiple-input single-output (MISO) systems.The proposed antenna consists of two hexagonalshaped split-ring resonators for dual-band operation with higher gain and metallic loadings between the rings to achieve a wide impedance bandwidth.Impedance modeling of the proposed antennas confirms the role of conductance and inductance of metallic loading for enhancing the antenna characteristics, and thus, the fabricated H-SRR antenna achieves dual-band features with improved impedance bandwidth of 50%/76% and a gain of 2.32/2.57dB at 2.4/5.2GHz frequency bands.The performance of the hexagonal SRR antenna is then investigated for space diversity applications in the 1 × 3 SIMO and 3 × 1 MISO systems with circular SRR antennas.In linear and spherical arrangements of the antennas, the channel capacity is found in the range of 2.7 to 4.8 Mbps at the 2.4/5.2GHz bands, which also confirms its dependency on the number of antennas as well as on the placement of antennas.
