RF-MEMS Switch for Reconfigurable With Half-Moon Slots on Elliptical-Shaped Patch Antenna for 5G Applications
A compact dual-band reconfigurable elliptical-shaped patch antenna designed in this article. The proposed patch antenna with rectangular strip lines and an elliptical with half-moon slots presented to operate dual bands. To achieve the reconfigurability, RF-MEMS switches proposed on rectangular strip lines of the patch antenna. The capacitive shunt type RF-switch designed the proposed elliptical antenna to operate at 5G applications. The displacement of the proposed RF-MEMS switch with an air gap of
$3~\mu $
m, the actuation of 5.02 V, and the stress of the proposed beam is bearable up to 85.7 MPa is observed. The reconfigurable elliptical-shaped patch antenna resonates at 8.34 GHz and 10.47 GHz with a reflection coefficient of −32.28 dB and −22.7 dB respectively. The operating frequencies and gains are observed at the RF-MEMS switch placed on a patch for dual bands for four states. At the state-I, two operating frequencies and gain are 8.4G Hz, and 10.52G Hz with 2.28 dBi, and 2.18 dBi. Similarly, state-II frequencies are 8.56 GHz, and 10.55 GHz with gains of 2.08 dBi, and 1.30 dBi; state-III frequencies are 8.49 GHz, 10.47 GHz with gains of 2.48 dBi, and 3.04 dBi; and state-IV, frequencies are 8.49 GHz, 10.49 GHz with gain of 2.58 dBi, and 2.64 dBi. The compact elliptical patch antenna was simulated and a measured value is presented in this article and also both values are agreed.
