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 )

measured input return loss

measured radiation pattern
