“…Various meandered line based microstrip patch antennas have been proposed in the literature. [11][12][13] However, high surface wave and metallic losses at higher frequencies make such antennas inefficient, especially when electrical size is small. 14 Dielectric resonator antennas are the potential replacement of printed antennas at higher frequencies because they have high gain and radiation efficiency as metallic losses are negligible in DRA due to the absence of metals.…”

This paper inspects a parasitic element-based inverted meandered U-shaped printed line fed hybrid MIMO DRA. The feed of a single element of the 2-elements hybrid MIMO DRA consists of a meandered shaped line coupled to the inverted L-shaped parasitic element printed on the top side of FR-4 substrate with a partial ground on the back. The rectangular-shaped alumina dielectric is placed over the feed to form the single element hybrid DRA. The individual element resonating at 3.40-4.32 GHz (23.83%) and 4.96-5.05 GHz (1.80%) achieves the dual-band characteristics by exciting multiple modes within the rectangular dielectric resonator. The low-profile Multiple Input-Multiple Output (MIMO) antenna configuration having an overall size of 0.57 λ Â 0.23 λ Â 0.14 λ mm 3 consists of two orthogonally placed hybrid rectangular DRAs. The inter-element isolation for a connected ground MIMO structure is better than 22 dB in the desired bands of operation without using any isolation improvement techniques. The MIMO diversity parameters are simulated and measured to validate the MIMO performance. The diversity metrics envelope correlation coefficient is below .175, and .15, the mean effective gain ratio is 0 dB, the total active reflection coefficient values are below 15 dB, and channel capacity loss values are below 0.5 bits/sec/Hz in the lower, and upper bands of operation which are within the recommended practical limits. The presented MIMO design achieved the peak gain of 12.87dBi, and minimum radiation efficiency of 83%, with stable radiation characteristics that make the antenna suitable for Sub-6 GHz 5G and WiFi-6 applications.
