Compact dual diversity antenna for RF data and wireless communication devices

摘要

A compact dual diversity antenna for RF data and wireless communication devices having a printed circuit board is disclosed. First and second PIFAs are mounted on the PCB in a spaced relationship. Each of the first and second PIFAs include radiating elements having ground planes and shorting posts. The ground plane of the second PIFA is disposed in the same plane as the PCB. The ground plane of the first PIFA is orthogonally disposed with respect to the ground plane of the second PIFA. First and second feed posts connect the first and second PIFAs to the PCB through RF feed lines. The first and second feed posts are disposed perpendicularly to one another.
