Wideband Aperture-Coupled Stack-Patch Antenna Design with Characteristic Mode Analysis

These days' RF devices, communication frequencies, and technology is advancing towards a higher frequency spectrum with wide bandwidth for higher data rate, miniaturization and portability. For high frequency and wide bandwidth a low loss, efficient and compact wideband microstrip antenna development with convenient analysis is crucial. In this paper, we developed a wide band highly efficient stack patch antenna for Ku-band and analyze the model with characteristics mode analysis. The developed antenna has −10dB impedance bandwidth from 13.1-15.2GHz and −30dB bandwidth from 14-14.5GHz. Higher impedance matching leads to higher efficiency and high gain for the target center frequency of 14. 25GHz.
