Abstract

Novel and compact CPW-fed antennas are proposed comprised of a fractal patch and modified ground-plane. The ground-plane is truncated at the center and includes dielectric notches at its side to enhance the antenna's impedance bandwidth. The dimensions of the notches effectively control the upper and lower band edges of the antenna. The optimized antenna operates across 2.95-12.81 GHz for S11 ≤ -10 dB. Omnidirectional radiation pattern is achieved over the full UWB frequency range. The miniaturized antenna has a total size of 14 × 18 × 1 mm(3). The characteristics of the proposed antenna are suitable for UWB wireless communication requiring low profile antennas.

摘要

提出了一种新型紧凑型共面波导馈电天线，它由一个分形贴片和改进的接地平面组成。接地平面在中心处截断，并在其侧面包括介质切口，以提高天线的阻抗带宽。切口的尺寸有效地控制了天线的上下频段边缘。优化后的天线在S11≤-10 dB时工作频率范围为2.95 - 12.81 GHz。在整个超宽带频率范围内实现了全向辐射方向图。该小型化天线的总体尺寸为14×18×1 mm(3)。所提出天线的特性适用于需要低剖面天线的超宽带无线通信。
