Abstract

|This paper presents a coplanar waveguide (CPW)-fed tri-mode hybrid antenna that is suitable for quad-band applications. The antenna design is compact, measuring only 30 (cid:2) 30 mm 2 , and consists of a zeroth-order resonator (ZOR) antenna, a torch-shaped monopole antenna, and a T-shaped slot antenna. The most signi(cid:12)cant feature of this design is its ability to provide three independent working modes, making it a hybrid antenna. By incorporating a Composite Right/Left-Handed Transmission Line (CRLH-TL) unit cell, the (cid:12)rst mode is excited as a ZOR antenna, corresponding to the lowest resonance at around 1.57 GHz. The second mode relies on the torch-shaped monopole antenna with two resonances at about 2.5 GHz and 3.5 GHz. The third mode employs the T-shaped slot antenna with a resonance at around 5.5 GHz. Experimental results demonstrate that the proposed antenna exhibits a wide and multi-band behavior with impedance bandwidths of 60 MHz (1.56{1.62 GHz), 210 MHz (2.30{2.51 GHz), 370 MHz (3.40{3.77 GHz), and 1100 MHz (5.05{6.15 GHz). This antenna can not only support the current GPS/WLAN/WiMAX systems but can also be considered as one element of a multiple-input-multiple-output (MIMO) antenna array for the (cid:12)fth-generation (5G) mobile communication in the sub-6 GHz frequency range.

四波段应用的三模混合天线

本文提出了一种适用于四波段应用的共面波导馈电三模混合天线。天线设计紧凑，尺寸仅为30 (cid:2) 30 mm 2，由零阶谐振器(ZOR)天线、火炬形单极天线和t形槽天线组成。这种设计最显著的特点是它能够提供三种独立的工作模式，使其成为一种混合天线。通过结合复合左右传输线(CRLH-TL)单元电池，(cid:12)第一模式被激发为ZOR天线，对应于1.57 GHz左右的最低谐振。第二种模式依赖于火炬形单极天线，具有约2.5 GHz和3.5 GHz的两个谐振。第三种模式采用谐振频率在5.5 GHz左右的t形槽天线。实验结果表明，该天线的阻抗带宽分别为60 MHz (1.56{1.62 GHz)、210 MHz (2.30{2.51 GHz)、370 MHz (3.40{3.77 GHz)和1100 MHz (5.05{6.15 GHz)，具有较宽的多频段特性。该天线不仅可以支持当前的GPS/WLAN/WiMAX系统，而且还可以被认为是用于sub-6 GHz频率范围内(cid:12)第五代(5G)移动通信的多输入多输出(MIMO)天线阵列的一个元件。
