© 2021 Chamber of Turkish Electrical Engineers.Investigative electromagnetic (EM) simulations for bended antenna designs, also used for wearable devices, plays an important role in the design process. The simulation for conformal antennas is time consuming also considering the effects of the presence of the feeding/beamforming network on the antenna performances. To tackle this drawback, a new simulation environment is created, where Keysight ADS tool is employed for modeling the initial microstrip antenna of which shape is determined using a bottom-up optimization (BUO) method. The employed BUO in the ADS environment significantly helps the designer in generating the antenna geometries that exhibit the required performances in terms of bandwidth and radiation patterns. Afterwards, the CST Microwave Studio (Dassault Systèmes) is used for bending the previously designed flat microstrip antenna, and accurately evaluate its performances by numerical simulations. To verify the efficiency of the proposed methodology, one bended microstrip antenna in the frequency band of 8.8-9.4 GHz is designed and the radiation pattern responses are depicted.
