Antenna Engineering

   

    Picture following shows a typical four steps antenna design flow :

    Step 1: Select the best antenna topology according mechanical constraint :

In this example, the space in Z axis is big, so we choose upright mono-pole PCB antenna

 

 

    Step 2: Run simulation

 

 

input return loss

 

radiation pattern and efficiency

 

    Step 3: Build antenna sample :

 

 

dummy sample for verifying antenna performance

 

real sample

    Step 4: Do fine turning according to the measurement of antenna performance parameters ( return loss and radiation pattern )
