Abstract :
A compact three way diversity antenna is described. The composite antenna consists of two elemental loop antennas placed on a small ground plane at right angles to each other and the third elemental antenna is a top loaded monopole. The feed structures for the three elemental antennas are described. The performance of the antennas is presented with measured data on the near back electric fields of the loop antennas.
