Abstract

This paper proposes a conformal trapezoid strip excited broadband hemispherical dielectric resonator antenna (DRA) design in ultra wide-band (UWB) low band 3.1-4.8 GHz for medical capsule endoscope applications. The proposed antenna can be conformal to the capsule dome and is also characterized by light weight, low profile, low cost, small size. A broadband trapezoid monopole receiver antenna is developed for transmission measurements. The UWB transmission loss characteristics in body tissue are exploited based on the measurement solution. Moreover, a successful video transmission from inside to outside body has been carried out based on multiband orthogonal frequency-division multiplexing (MB-OFDM) scheme using the proposed antennas. Additionally, a preliminary research based on a binary phase-shift keying (BPSK) carrier transmission has been done to investigate the potential capsule endoscope communication performance.
