A triple-band substrate integrated waveguide (SIW) with dielectric resonator antenna (DRA) for fourth-generation (4G) and fifth-generation (5G) applications is proposed and analyzed in this paper. Loading SIW with DRA allows for a wide bandwidth, low losses, and fabrication ease. The proposed antenna can transmit and receive data independently by covering LTE Band 3 at 1.8 GHz, LTE Band 8 at 2.6 GHz, and 5G n77 at 3.7 GHz. A U-shaped cut is applied to achieve the targeted multi-resonance frequencies. The antenna obtains high bandwidths of up to 19.50% with 4.9 dBi gain and 81.0% efficiency at 1.8 GHz, 6.58% bandwidth with 4.4 dBi and 72.7% efficiency at 2.6 GHz, and 8.21% bandwidth with 6.7 dBi and 73.5% efficiency at 3.7 GHz. The simulated and measured results agree well. The proposed antenna is feasible for 4G and 5G applications.
本文提出并分析了一种用于第四代（4G）和第五代（5G）应用的带介质谐振器天线（DRA）的三频段基片集成波导（SIW）。在SIW中加载DRA可实现宽带宽、低损耗且易于制造。所提出的天线通过覆盖1.8 GHz的LTE 3频段、2.6 GHz的LTE 8频段和3.7 GHz的5G n77频段，能够独立发送和接收数据。采用U形切口来实现目标多谐振频率。该天线在1.8 GHz时获得高达19.50%的高带宽，增益为4.9 dBi，效率为81.0%；在2.6 GHz时带宽为6.58%，增益为4.4 dBi，效率为72.7%；在3.7 GHz时带宽为8.21%，增益为6.7 dBi，效率为73.5%。仿真和测量结果吻合良好。所提出的天线对于4G和5G应用是可行的。
