A Broadband Array Antenna for 5G Based on Minkowski-Like Fractal Structure
摘要
Abstract
To meet the demands of 5G communications,a broadband array antenna based on a Minkowski-like fractal structure has been designed.A 1.2 mm thick FR4 substrate with a dielectric constant of 4.4 and overall dimensions of 360 mm×158 mm are utilized in the array antenna.Comprising four linearly arranged elements,each microstrip patch element of the array is etched with a 2nd-order Minkowski-like fractal structure.A Wilkinson power divider that splits one input into two outputs is replicated and transformed into a 1-to-4 power divider with each output feeding one of the 1×4 arranged elements.The ground plane is formed by connecting multiple rectangles with cut corners.The array antenna operates within the 1～6 GHz frequency range,achieving gains from 2～9.18 dB and omnidirectional radiation characteristics.HFSS simulations and measurement results verified the accuracy and practicality of the design.This research demonstrates the potential of fractal array antennas in multi-band operation and broadband applications,providing both theoretical and practical foundations for antenna design in 5G and higher frequency communications technologies.关键词
