本文提出了一种覆盖医疗体域网络（MBAN）和2.4 GHz工业、科学、医疗频段的反射器背端微带贴片天线。提出了电磁耦合馈线与反射器的组合，以拓宽阻抗带宽，降低天线对人体影响的灵敏度。该天线采用单向波束辐射，满足了在体和离体传播的要求。采用三层组织模型表示人体，进行人体通道仿真。该天线建立在介电常数为3.3的基片上，有限地平面为50mm × 50mm。当fc=2.45 GHz时，该天线的-10 dB S11带宽为7.7%（机身上）和8.5%（机身外），增益为6.6 dBi。该天线具有良好的机身性能，在MBAN中具有广阔的应用前景。
This paper presents reflector-backed microstrip patch antenna covering the medical body-area network (MBAN) and a 2.4 GHz industrial, scientific, medical band. The combination of electromagnetic coupled feed line and reflector is proposed to widen impedance bandwidth and reduce antenna sensitivity to human body effects. The proposed antenna radiates in unidirectional beam to meet the requirement of on- and off-body propagation. 3-layer tissue model is used to represent human body for on-body channel simulation. The antenna is built on substrate with permittivity of 3.3 and finite ground plane of 50mm × 50 mm. The antenna, when evaluated at fc=2.45 GHz, achieves -10 dB S11 bandwidth of 7.7% (on-body) and 8.5%(off-body), and realized gain of 6.6 dBi. Good on-body performance of the proposed antenna shows its prospect in MBAN.
