Abstract

A dual frequency filtenna (filtering antenna) for the fifth generation (5G) millimeter wave (mmWave) applications is proposed. The proposed antenna with a size of 6×6mm consists of a rectangle patch and a substrate integrated waveguide (SIW) cavity. The resonant mode in SIW cavity are TE102 (for N258 band) and hybrid TE202 mode (for N260 band). The antenna is low profile with only 0.789 mm thickness including two dielectric layers and a bounding layer. The introduction of round and rectangle slots enhanced the frequency filterability. The operating frequency band is from 24.61 GHz to 27.74 GHz and 39.50 GHz to 42.15 GHz, almost covering 5G N258 (24.25-27.5 GHz) and N260 (37–40 GHz) mmWave bands with reflection coefficient less than -10 dB. The average gain in passband is 4.5 dBi and 1.6 dBi and the relative impedance bandwidth is 11.96% and 6.49%, respectively. The merits make the proposed dual frequency filtenna a good candidate for 5G mmWave applications.

TE102和混合TE202模式的双频滤波器，用于5G毫米波N258/N260应用

提出了一种用于第五代(5G)毫米波(mmWave)应用的双频滤波天线(滤波天线)。该天线的尺寸为6×6mm，由矩形贴片和基板集成波导(SIW)腔组成。SIW腔内谐振模式为TE102 (N258频段)和混合TE202模式(N260频段)。该天线外形较低，厚度仅为0.789 mm，包括两个介电层和一个边界层。圆槽和矩形槽的引入提高了频率滤波能力。工作频段为24.61 GHz ~ 27.74 GHz和39.50 GHz ~ 42.15 GHz，几乎覆盖了反射系数小于-10 dB的5G N258 (24.25 ~ 27.5 GHz)和N260 (37 ~ 40 GHz)毫米波频段。通带平均增益为4.5 dBi和1.6 dBi，相对阻抗带宽分别为11.96%和6.49%。这些优点使所提出的双频滤波器成为5G毫米波应用的良好候选者。
