Abstract

This paper presents design and simulation of an ultra wide band antenna for Customer Premise Equipment (CPE) in the TV White Space (TVWS) spectrum band operating between 420 MHz – 1040 MHz. Integrated, lightweight and wideband antennas have received much attention following the development of wireless communications. The M-shaped monopole is a lightweight, wideband antenna suitable for integration. The size of the antenna has been reduced by using a T-shaped ground plane. The wide bandwidth and reduced size of this antenna makes it desirable for use in TVWS CPE communication systems. The antenna elements are designed on low cost FR4 substrate with εr = 4.4 and tanδ = 0.02. The M-shaped monopole is fed by a 50 Ω microstrip line. Total volume of the antenna is 198.32 × 111.11 × 1.6 mm3. The antenna shows an impedance bandwidth for VSWR ≤ 2 in the frequency range of 420 MHz – 1040 MHz. The gain of this antenna is between 2.24 dB to 4.8 dB in the entire band of operation. The radiation pattern is omnidirectional in both E and H-planes. Radiation and total efficiency of the simulated M shaped monopole antenna achieved is approximately 99 %.

用于TVWS CPE的M形超宽带单极天线

本文设计并仿真了一种用于420mhz - 1040mhz电视空白频段客户端设备(CPE)的超宽带天线。随着无线通信技术的发展，集成化、轻量化、宽频化的天线越来越受到人们的关注。m型单极子是一种轻量级的宽带天线，适合集成。天线的尺寸通过使用t形接地面而减小。该天线的宽带宽和小尺寸使其适合用于TVWS CPE通信系统。天线元件设计在低成本FR4衬底上，εr = 4.4, tanδ = 0.02。m型单极子由一条50 Ω微带线馈电。天线的总体积为198.32 × 111.11 × 1.6 mm3。在420 MHz - 1040 MHz的频率范围内，天线的阻抗带宽为VSWR≤2。该天线在整个工作频带的增益在2.24 dB到4.8 dB之间。E面和h面辐射方向图都是全向的。仿真得到的M形单极天线的辐射效率和总效率约为99%。
