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
