Electromagnetic Bottom-Up Optimization for Automated Antenna Designs

This paper presents an automated design of antennas by using bottom-up optimization-oriented strategy in conjunction with a full-wave electromagnetic (EM) analysis. The proposed approach firstly set up a co-simulation environment between a commercial Electronic Design Automation (EDA) software and a numerical analyzer. Then bottom-up optimization method is applied by increasing the number of microstrip transmission lines (TLs) and examining various structures of TLs for modeling the antenna geometry. The optimization process is automated using ADS and MATLAB. ADS is preferred among other EDA tools as EM analysis criteria can be optimized well in this tool. In particular, the optimization method is applied for designing two single antennas in the operation bands of 16.3 GHz - 17.43 GHz (Ku band) and 10.1 GHz-10.9 GHz (X band), respectively. The optimized antennas exhibit gain performance between 5.57 dB-8.6 dB and 2.12 dB-4.1 dB, respectively. The simulated results have also been positively tested in Ansys HFSS tool.
