I've design a monopole microstrip antenna. The range frequency is 400-406 MHz. For this bandwidth, the VSWR is 1:1.4. I think it's good enough. The problem is that the material is -24.8 dB and the directivity is 1.8 dB, so the gain is small. What should I do? Does anyone know how to reduce the material loss? Thank you.
