    Got negative gain in design circular patch antenna in HFSS. I found It's because my antenna is not radiating despite good matching. Please help?

    Hi everyone, I have designed a circular patch antenna array in HFSS 2018.2 environment working at the ISM band. I got negative gain(-10.6dBi) and realized gain(-10dBi) in my design at operating frequency. After analysis I found that their radiation efficiency is very less means the antenna is...
