Design of compact multi stub resonator based flexible monopole antenna for 5G wearable applications in N77 and N78 bands (opens in new tab)

In this article, a simply structured small-size multi stub resonator based flexible monopole wearable antenna is proposed for N77 (3.3–4.2 GHz) and N78 (3.3–3.8 GHz) bands of 5G communication that was design on the RT/Duroid 5880 substrate with a thickness of 20 mil (0.508 mm). The presented antenna configuration comprised of a monopole antenna and a vertically aligned symmetrically loaded multi stub resonator which excite resonant mode at 3.525 GHz for N77 and N78 bands of 5G applications.
