摘要

提出了一种用于医用胶囊内窥镜的超宽带(UWB)低频段3.1-4.8 GHz共形梯形带激励宽带半球形介质谐振器天线(DRA)设计。所提出的天线既能与胶囊穹顶保形，又具有重量轻、外形低、成本低、体积小的特点。研制了用于传输测量的宽带梯形单极子接收天线。基于该测量方案，研究了人体组织中的超宽带传输损耗特性。此外，基于多频段正交频分复用(MB-OFDM)方案，利用所设计的天线成功实现了人体内外视频传输。此外，本文还对基于二相移键控(BPSK)载波传输的胶囊内窥镜通信性能进行了初步研究。

An UWB capsule endoscope antenna design for biomedical communications

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.
