A Wearable Dual-Band Circularly Polarized Patch Antenna for Wearable Applications
A dual-band circularly polarized (CP) wearable microstrip antenna is presented for flexible wireless applications. The proposed antenna features a rectangular patch with diagonally truncated corners, embedded with hexagonal, U-shaped, and circular slots to enhance CP performance and impedance matching. The antenna is realized on a wool-based textile substrate, offering mechanical flexibility suitable for on-body integration. It operates over two bands, with impedance bandwidths of 16.31%(4.84-5.7 GHz) and 20.9%(6.81-8.4 GHz). The axial ratio (AR) bandwidths of 1.51%(5.26-5.34 GHz) and 2.7% (6.91-7.1 GHz) right-handed circular polarization are maintained across both operational bands, with realized gains of 3.3 dBi and 11 dBi at 5.3 GHz and 7.02 GHz. The antenna's compact, conformal structure makes it suitable for wearable AR/VR, biomedical sensing, and IoT-enabled applications.
