Compact dual diversity antenna for RF data and wireless communication devices
First Claim
1. A compact dual diversity antenna for RF data and wireless communication devices having a printed circuit board (PCB), comprising:
- a first planar inverted F antenna (PIFA) mounted on the PCB;
and a second planar inverted F antenna (PIFA) mounted on the PCB in a spaced relationship to said first PIFA;
each of said first and second PIFAs including radiating elements having ground planes and shorting posts;
said ground plane of said second PIFA being disposed in the same plane as said PCB;
said ground plane of said first PIFA being orthogonally disposed with respect to said ground plane of said second PIFA;
a first feed post connecting said first PIFA to the PCB through a RF feed line;
a second feed post connecting said second PIFA to the PCB through a RF feed line;
said first and second feed posts being disposed perpendicularly to one another.

Abstract
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.
