Description
Summary:Investigators are looking at radio frequency ranges that may suit cellular data consumers' growing requirements. Terahertz's ( THz) frequency range is vital for high-speed data communication in wireless gadgets and has indignant the interest of researchers. A novel spiral-shaped patch and diffracted ground-based MIMO antenna structure are presented. The overall dimensions of the structure are 600 µm by 800 µm. The polyamide material is used as a substrate. The analysis among 1  × 1, 1  × 2, 2  × 1 and 2  × 2 MIMO antenna structures are carried out. Performance in reflectance response, Bandwidth, gain, radiation pattern and directivity are analyzed. The proposed structure provides the multiband response with a minimum reflectance response of − 30.51 dB, a bandwidth of 10 THz, peak isolation of 36.99 dB, a maximum normalized directivity of 103 0 and a peak gain of 39 dB. ECC TARC, CCL and D.G. were considered for the performance observation. A comparison of the presented structure with other articles is included in the manuscript. The proposed work suits biomedical imaging, short-distance communication, healthcare and WBAN applications.
