摘要
设计了一种宽带圆极化贴片天线，用于生物医学遥测应用。工作频段为ISM (Industrial, Scientific, and Medical) 2.4GHz。该天线通过在地平面上切割一个十字形槽，截断辐射贴片环上的一对角，实现了阻抗和轴向比带宽的增强。HFSS模拟阻抗和AR带宽分别为16.15%和6.09%。天线的总体积为127mm3。
A wideband implantable antenna with circularly polarization
A wideband, circularly polarized (CP) patch antenna is designed for biomedical telemetry application. The operating band is Industrial, Scientific, and Medical (ISM) of 2.4GHz. By cutting a cross-shaped slot on the ground plane and truncating a pair of corners on the radiating patch ring, the presented antenna can acquire enhancement for impedance and axial ratio (AR) bandwidths. The simulated impedance and AR bandwidths in the HFSS phantom are 16.15%and 6.09%, respectively. The total volume of the antenna is 127mm3.
