2.4GHz Printed Antenna with Diversity and special feed

This is an example printed antenna design with diversity.

The special feed method exhibits a wider bandwidth.

2.4GHz Printed Antenna with Diversity

This is an example diversity antenna configuration, operating in the 2.4GHz ISM band.

It is miniaturized by folding the open end of the PIFA. Because of the higher electric field at these nodes, the effect of folding has a strong influence on the antenna tuning, so careful design must be exercised.

While the antenna spacing is close, antenna diversity gain is still acceptable. This is mainly obtained through polarization differences.
