A compact dual‐band circular patch antenna is designed for implanted biomedical data telemetry systems. Several miniaturization techniques were applied to cover dual bands. The antenna has a radius of 7.5 mm, a thickness of 1.92 mm and a total volume of 340 mm 3 . The antenna covers MedRadio (401–405 MHz), MICS (402–405 MHz), and ISM bands (433.2–434.8 MHz, 2.4–2.5 GHz). The −10 dB bandwidths are 346–460 MHz (114 MHz) and 2.37–2.63 GHz (260 MHz). The designed antenna was fabricated and its performance was tested inside flesh samples.
