The article proposes a wearable antenna printed on a flexible material,polydimethylsiloxane(PDMS),composed of a radiating patch and a ground plane.The antenna is fed by a microstrip line method and printed on both sides of the PDMS dielectric substrate,intended for use in body area network communication wearable devices.Based on a planar monopole antenna model,the design achieves a linear standard for the antenna's reflection coefficient phase curve,with the antenna's maximum gain fluctuating between 2.8 dBi and 5.2 dBi indicating good continuity.The performance impact on the antenna after bending is minimal,meeting the design requirements for wearable antennas.Simulation results show that the antenna performs stably in the 3.1 GHz-10.6 GHz frequency band,achieving coverage of the frequency range specified for ultra-wideband antennas.
