A novel design of bow-tie antennas array for uplink C-band applications based on fast and efficient computational equivalent model

摘要

This paper proposes an original application and for the first time a novel manufactured design of series fed Log-periodic microstrip antennas array LPA composed of seven bow-tie radiating elements functioning in the uplink C-band frequency from 6.12 to 6.58 GHz based on the bow-tie antenna equivalent model (BAEM). The model is used to optimize the antenna array in a record time and calculate the return loss with a sufficient precision. To prove the effectiveness of the suggested BAEM model, a comparison has been achieved between the CST Microwave studio software, Momentum of Agilent, BAEM model and measurements. The comparison of measured and simulated results shows good agreement. The measured results show that a bandwidth from 6.12 to 6.58 GHz is obtained. The obtained results show the effectiveness of this method to analyze such types of antennas.
