Broadband CTS antenna array at E-band


A compact 32-slot continuous transverse stub (CTS) antenna array operating at E-band is proposed here. It is excited by a hollow parallel plate waveguide (PPW) corporate feed network to insure a broad band operation. A parabolic pillbox coupler is used to create the requested current line exciting for the PPW beamformer. The pillbox coupler is fed by a substrate integrated waveguide (SIW) horn located in the focal plane of the parabola. The most important features of the antenna building blocks are described in detail, and the numerical results demonstrate the excellent performance of the proposed antenna. A reflection coefficient lower than -19 dB and a gain larger than 31 dBi are obtained over a 19% fractional bandwidth spanning between 71 and 86 GHz. The proposed antenna architecture is an innovative solution for E-band backhauling applications for next generation 5G networks. © 2017 Euraap.
