摘要

In this article, a novel linear mmWave antenna array with series-feed network is proposed to enhance the bandwidth and reduce sidelobe level without increasing the patch size. The proposed linear array is consisted of four identical wideband array elements, which are all under operation TM10 and TM02 modes by loading shorting pin and rectangular slots. Additionally, through loading symmetry circle-shaped slots for the four elements, impedance matching of linear array is achieved. Furthermore, multi-parameters unified-optimization (MPUO) based on imperial competition algorithm (ICA) is proposed to uniformly optimize all linear array parameters. To verify this design, the proposed linear array is fabricated with a small patch area of 7.5 x 3.914 x 0.254 mm(3). The measured results show that the bandwidth is enhanced to 2.05GHz, which is 0.57GHz wider than that of simulation. The simulated peak gain reaches 13dBi while the sidelobe level is reduced to about -19 dB at 28.6GHz. Moreover, the computation cost using MPUO is reduced by 98.12% compared with that of independent parameters optimization.
