Re: Help with λ/4 monopole antenna.

Please observe the MIMO antenna.pdf i have attached.
In general,when defining port in hfss,the ground is below the dielectric and the radiating element at the top of dielectric.
But in this design,both the radiating element(monopole antenna) and the ground are on the top of dielectric(fr-4).In this case,how should i define the port?

whats the problem ? they did a come type of design its like a dipole microstrip and its type of RFID antenna

u can try using a waveguide port in hfss

i think in this structure lump port is best and wave port make some problem

You can model PCBs using AN-SOF. You can ask for a free version in this link
