A compact tapered antenna with a meandered strip line for implanted biomedical applications is proposed. The proposed antenna can be operated at a medical device radio communication service (MedRadio) band, a long-term evolution (LTE) band 8, an LTE band 11, and an industrial, scientific, and medical (ISM) band. A linear tapered structure is introduced to improve antenna gain, and simultaneously, a meander line is adopted to lower the resonant frequency to the MedRadio band and reduce the size of the proposed antenna. The proposed compact tapered implanted antenna is fabricated and measured using a skin-mimicking gel. The measured results are in good agreement with the simulated ones. The proposed antenna has gain values of −15.55 and −8.37 dBi in MedRadio and ISM bands, respectively. Furthermore, the salient features of the proposed antenna make it a candidate for wireless biotelemetric applications.
