A wearable fabric antenna on the upper arm is presented for on‐body applications in the MedRadio band. The antenna was manufactured on a fabric substrate and operated at the Medical Device Radio Communications Service band (MedRadio band: 401–406 MHz). The antenna was designed to steer the beam directions. The use of two artificial switches enables a beam‐steering capability. The dimensions of the proposed antenna are 50 × 20.5 × 0.66 mm 3 (676.5 mm 3 ), and it utilises a fabric substrate ( ε r = 1.92, tan δ = 0.023). A one‐layer skin model ( ε r = 46.74, σ = 0.69 S/m) is adopted for antenna simulation and measurement.
