Summary: A wideband differentially-fed slot antenna with circularly polarized radiation is proposed for mmWave applications. A novel method of using stepped corner-shaped slot is utilized to establish wideband CP radiation. The antenna design includes orthogonal radiation and phase delay, as well as modifications to enhance the axial ratio and impedance bandwidth. The antenna element, linear array, and planar array were designed and fabricated to verify performance. Simulated and measured results demonstrate wide overlapped impedance and AR bandwidths for both the linear and planar arrays. Compact size and wide bandwidth make this antenna a promising candidate for mmWave applications.

Summary: This article proposes a series-fed, single-layer dual-circularly polarized slot array antenna that is fed by a stepped ridge gap waveguide (RGW) at the 77-GHz band. The antenna is capable of generating dual-circularly polarized waves, making it suitable for next-generation polarimetric radar in automotive applications. The antenna consists of eight columns of linear arrays and two feeding ports for exciting the slots. The design process and measured results are presented in this article. The measured results demonstrate that the achieved gain of the proposed antenna is above 27.3 dBi, with an axial ratio of about 2 dB over the frequency range of 76-79 GHz, exhibiting dual-CP patterns. The S-11 and S-22 values for the proposed antenna are below -10 dB, and the measured port isolation is above 17.5 dB.
