展示了低损耗树脂材料上自互补超宽带天线的实际实现。通过模拟和实验阐明了宽带特性对尺寸和形状的依赖性。自互补天线与 50 欧姆系统阻抗匹配，利用 UWB 频段的 3 级切比雪夫变压器，在树脂材料上设计和制造（相对介电常数；/spl epsiv//sub r/=3.6）。使用 30 mm/spl 次/60 mm 尺寸的天线，在 3.1 至 10.6 GHz（UWB 频段）的频率范围内测得的回波损耗小于 -9.8 dB，测得的绝对增益为 0-3 dBi。采用 /spl epsiv//sub r/=10.2 的树脂材料设计和制造的尺寸减小的天线（20 毫米/spl 倍/40 毫米）可提供低于 -7.8 dB 的回波损耗和各向同性辐射图。
Practical realizations of self-complementary ultra-wideband antennas on low-loss resin materials are demonstrated. Dependences of broadband characteristics on sizes and shapes are clarified by simulations and experiments. The self-complementary antennas impedance-matched to a 50-ohm system, utilizing a 3-stage Chebyshev transformer over the UWB band, were designed and fabricated on a resin material (the relative permittivity; /spl epsiv//sub r/=3.6). A measured return loss of less than -9.8 dB and a measured absolute gain of 0-3 dBi over a frequency range from 3.1 to 10.6 GHz (the UWB band) were obtained with a 30 mm/spl times/60 mm sized antenna. A reduced sized antenna (20 mm/spl times/40 mm), designed and fabricated on a resin material of /spl epsiv//sub r/=10.2, delivered a return loss of less than -7.8 dB with an isotropic radiation pattern.
