Abstract
Abstract
This article explores and develops a two-port MIMO Dielectric Resonator Antenna. The proposed antenna consists of two rectangular DRAs on the X-axis, fed by a trapezoidal conformal patch on the Y-axis. The proposed antenna may be 3D manufactured using a normal 3D printer and both DRAs are integrated with the substrate to minimise mounting error and improve mechanical strength, which were previously the typical constraints in DRAs. Rectangular Complimentary Split Ring Resonators (R-CSRRs) and Circular Complimentary Split Ring Resonators (C-CSRRs) enable the proposed antenna to be band-notched. The R-CSRRs control the 5–5.75 GHz range, whereas the C-CSRRs control the 4.4–4.8 GHz band, which are the commercial band. By keeping both ports orthogonal, the isolation between them was lowered to less than −15 dB in the operational bands. Later, with the substrate cavity, isolation drops to −19 dB for the operational bands. The suggested antenna is MIMO capable and covers the 3.4 GHz of ISM band (3.4–6.8 GHz). The antenna has a 4 dBi, 3.7 dBi and 6.9 dBi gain in the first, second, and third resonance frequencies. Excellent MIMO capabilities and ease of construction and feeding make this 3D printed antenna suited for the ISM band.
