摘要
小型MIMO圆极化天线尺寸为56 x 60 x 1.5748 mm3，专为UHF RFID, pc和5G应用而设计。C型和e型槽沿着天线两侧的弯曲线形成，为0.7-1GHz、1.6-2.48 GHz和3.5-4.2 GHz频段带来共振。DGS技术也被用于提高性能和降低辐射元件之间的相互耦合。为了更好地匹配阻抗，在天线上方放置一个“T”形短段。该天线为各自的频段提供了15 dB、20 dB和29 dB的良好隔离。利用Ansys HFSS软件对分集参数ECC、DG、TARC、MEG和辐射方向图进行仿真。UHF RFID和5G频段的轴比小于3db。该天线保证了无线应用中良好的MIMO天线效果。
Small MIMO Antenna with Circular Polarization for UHF RFID, PCS and 5G Applications
A small MIMO circularly polarized antenna with a 56 x 60 x 1.5748 mm3 is designed for UHF RFID, PCS and 5G applications. The C and E-shaped slots are created along with the meander line at both the sides of the antenna to bring resonance for frequency bands from 0.7–1GHz, 1.6–2.48 GHz and 3.5–4.2 GHz. DGS technique is also used to enhance the performance and lowers the mutual coupling between the radiating elements. A ‘T’ shape stub is placed above the antenna for better impedance matching. The antenna offers good isolation of 15 dB, 20 dB and 29 dB for the respective bands. The diversity parameters like ECC, DG, TARC, MEG and radiation pattern are simulated using Ansys HFSS software. The axial ratio is less than 3 dB for UHF RFID and 5G bands. This proposed antenna assures good MIMO antenna results for wireless applications.
