Abstract
In this paper, a UWB–MIMO antenna with the WLAN band-notch (5.1–5.85 GHz) characteristic is offered. This antenna consists of two radiated patch feeding with a tapered line and fabricated on abundantly available FR-4 substrate having the size of 36 × 22 × 1.6 mm3. A notched-band response is achieved by introducing an open-ended stub on the ground plane. Results illustrate that the designed antenna has an impedance bandwidth from 3.1 to 11.2 GHz as well as good isolation i.e. S21 ≤ − 30 dB. Radiation efficiency is greater than 0.75 except the notched band is < 0.5. Diversity performance is also set the new paradigm in terms of ECC (≤ 0.008), TARC (≤ − 25 dB), CCL (≤ 0.3 bits/s/Hz), Mean effective gain ratio (MEGi) ≅ 1 and directive gain (≥ 9.95 dB) except the notched band. Proposed antenna characteristics are also found suitable for a human interface device, low-cost, and easily fabricated. Simulated results of the proposed antenna are tested and verified by the experimental results.
