Abstract

A new compact planar notched ultrawideband (UWB) antenna is designed for wireless communication application. The proposed antenna has a compact size of 0.182λ × 0.228λ × 0.018λ where λ is the wavelength of the lowest operating frequency. The antenna is comprised of rectangular radiating patch, ground plane, and an arc-shaped strip in between radiating patch and feed line. By introducing a new Tuning Fork-shaped notch in the radiating plane, a stopband is obtained. The antenna is tested and measured. The measured result indicated that fabricated antenna has achieved a wide bandwidth of 4.33-13.8 GHz (at -10 dB return loss) with a rejection frequency band of 5.28-6.97 GHz (WiMAX, WLAN, and C-band). The effects of the parameters of the antenna are discussed. The experiment results demonstrate that the proposed antenna can well meet the requirement for the UWB communication in spite of its compactness and small size.

摘要

一种新型紧凑型平面缺口超宽带（UWB）天线被设计用于无线通信应用。所提出的天线尺寸紧凑，为0.182λ×0.228λ×0.018λ，其中λ是最低工作频率的波长。该天线由矩形辐射贴片、接地平面以及位于辐射贴片和馈线之间的弧形带组成。通过在辐射平面引入一个新的音叉形缺口，获得了一个阻带。对该天线进行了测试和测量。测量结果表明，制作的天线在-10dB回波损耗下实现了4.33 - 13.8GHz的宽带宽，以及5.28 - 6.97GHz（WiMAX、WLAN和C波段）的抑制频段。讨论了天线参数的影响。实验结果表明，所提出的天线尽管尺寸紧凑小巧，但仍能很好地满足超宽带通信的要求。
