Abstract :
These simulated results are presented for two chip antennas mounted on PCB to result a ball-like or isotropic radiation pattern. If these two chip antennas are arranged suitably by feeding power with the same amplitude and 180° phase difference, the near isotropic radiation pattern can be obtained. It is really interesting and special to achieve such a radiation pattern.
