Abstract

With the wide demand for wearable gadgets, flexible antennas have emerged to fulfill the requirement of uninterrupted connectivity with stringent radiation behavior. A compact triple-band antenna is proposed to operate at mmWave band. A liquid crystal polymer substrate is used as it has good mechanical and resistive properties against bending and is very cost-efficient. The chosen dimension of the substrate is 0.635λ_0x0.635λ 0, where λ0 is the lower operating mmWave wavelength. The proposed antenna operates at 31.76 GHz, 34.46 GHz, and 49.87 GHz with good impedance matching, having reflection coefficients of -23.3dB, -15.81dB, and -27.97dB, respectively. The fractional bandwidth of the designed antenna is 10.97%, 0.99%, and 7.45%. The antenna is validated for bending analysis at angle 6 varying from 8.6^0 to 5.7^0 along the two-dimensional axis. The specific absorption rate (SAR) is 3.3 W/kg and 2.14 W/kg at 15 mm and 20 mm distances. The structure has attained the maximum gain of 6.59, 4.54, and 9.25 dBi, respectively. The radiation pattern is bidirectional with HPBW of 44^0, 42^0, and 36^0 in the E-plane. The radiation pattern is turned to directional over the phantom model with an HPBW of 20^0 and a maximum gain of 10.4 dBi. Finally, the proposed structure is simulated by placing it over a helmet for military hostile surveillance applications.
