Abstract

Abstract : A novel, compact, semi‐circular, implantable, planar‐inverted‐F antenna (PIFA) is presented for the medical implant communications services (MICSs) band (402–405 MHz). By cutting three arc‐shaped slots in a semi‐circular patch, the proposed antenna can obtain effective size reduction. The total volume of the proposed antenna, including substrate and superstrate, is about 151 mm 3 . A bandwidth of 25 MHz is obtained at return loss of 10 dB. In addition, the radiation and specific absorption rate (SAR) performance of the antenna are examined and characterised.
