Abstract-This paper proposes a 77 GHz microstrip series-fed patch antenna array for automotive radar applications. Based on the Taylor Distribution Principle, we designed a six-unit series-fed weighted antenna array. A Wilkinson 1 : 8 un-equal divider is employed to connect eight antenna arrays to form a whole planar antenna. In antenna far-field patterns, the E-plane side-lobe level is approximately below −20.15 dB, and the H-plane side-lobe level is about −15 dB. Good accordance is obtained between simulated and measured results. The designed antenna has great value in the application fields of 77 GHz automotive radar antenna.

“…This agreement shows that the proposed method of analysis and the transmission line model are consistent with each other, provided mutual coupling is neglected in the proposed method and both loss and feed reactance are accounted for in the transmission line model. Even more importantly, this demonstrates that when analyzing a series-fed array using transmission line theory, it is important to account for the feed reactance, an aspect that perhaps has not been fully appreciated, though some previous works have included it [7]. Figure 4 also shows that when the feed reactance is ignored in the transmission line models (models (b) and (c) the radiation patterns are skewed, due to phase error in the patch amplitudes, consistent with the observation made in [8].…”

“…Modified forms of the transmission line model and cavity model have been used for analyzing series-fed patch arrays in [5] and [6], respectively. In [7] an extended transmission line model was introduced which extends the transmission line model of [4]. A certain amount of phase shift error in the array design was observed in the transmission line modeling of large series-fed arrays in [8].…”

A novel method of analysis for a linear series-fed microstrip antenna array is developed, which is based on a set of canonical coefficients defined for the elements of the array. This method accounts for the mutual coupling between the elements, and allows for a design that has an arbitrary amplitude and phase of the radiating patch currents. This method has the simplicity of a CAD approach while maintaining an accuracy close to that of a full-wave method. The coefficients involved in the formulation are determined by full-wave simulation on either a single patch element or on two patch elements (for mutual coupling calculations).Index Terms-series-fed array, microstrip array, linear array, microstrip antenna, patch antenna, mutual coupling.

“…Alternatively to the lens concept a patch column with N E ≫ 2 could be used for the beam shaping in the E-plane. A tapered aperture distribution for low E-plane side lobe level (SLL) could be achieved with tapered patch widths along the column, as presented in [5], but this competes against the small array spacing d H,col in the ULA. A patch column antenna without lens, equal patch widths along the column and N E = 16 was found to provide the desired beamdwidth and is used as a reference antenna in the following.…”

This paper introduces a novel dielectric lens antenna configuration for automotive radar applications. A cylindric lens fed by a uniform linear array (ULA) accomplishes elevation beam shaping and simultaneously allows for the application of array signal processing in the azimuth plane. Measured and simulated radiation patterns show a superior performance compared to a conventional antenna concept without lens.
