Abstract
Filter plays important roles in many RF/microwave circuits. Emerying wireless communication applications continue to challenge RF/microwave filter with ever more stringent requirements-higher performance, small sizer, lighter weight, and lower cost. A Ka-band Hairpin coupling structure dual-band filter prototype is presented, each branch of which has the length of a quarter wavelength of two-band center frequency. Then the filter prototype is optimized based on the PSO algorithm and IE3D simulation software, and the size of ultimate structure of optimization is on the small side, which is 5.5mm×2.7mm. And the variation of the two-band insertion loss is 0.5dB, and S11 of the two-band drops to-28dB, and the layout of the filter is completed at last.关键词
