Abstract
Section titled āAbstractāThis paper proposes a wearable reconfigurable antenna which can be operated in sub-6GHz, V-band and D-band. In the sub-6GHz band, the dual loop antennas are combined with a diode switch to achieve multi-mode switching. In the V-band, a controllable beam from 0 to 360 degrees is achieved by using six combined Vivaldi antennas with a diode switch to switch between beam directions. The diamond-shaped monopole antenna designed for the D-band achieves extremely high transmission rates at close range and has upward-facing directional radiation. The antennas are available in the sub-6 GHz bands such as 2–2.4, 2.9–3, 4.3–4.7, 5.75–6.05, and 6.6–6.9 GHz. The antenna design in the V-band can cover 19.78% (41-50 GHz) of the fractional bandwidth with a reflection coefficient below the −10 dB standard. In the D-band diamond monopole antenna, the reflection coefficient can reach −10dB standard covering 16.25% (139.6–164.3GHz) of the fractional bandwidth, and with directional radiation, the maximum radiation can reach 12dBi.
