REQ: Planar inverted-F Antenna Design

Hi all,

We are going to use 1.8GHz and 2.4GHz Planar inverted-F antenna for design. Any one has experience on the simulation on this type of antenna.

What is the major difference between planar and non-planar inverted antenna.

Hi, Rayengine!

My colleague has built two of such antennas (unfortunately non-planar), for 900 and 1800MHz (used as detector of mobile phones in a jail!).
He successfuly designed it in IE3D full-wave MoM simulator. I'll ask him for details if you want.

Thanks for help, please sent to me! My email: ray_wmwong@hotmail.com.

Moreover, as I heard from some antenna design, the planar inverted-F has a broaden bandwidth, so how can we control the planar area and where we place the feeding point because it is not so single like a L-antenna? It is now three-dimensional structure.

Thanks in advance

this book have extremly information that u may need.

hope to help

You may like to check the book broadband compact antenna or the paper by BL Ooi on broadband stack antenna which has far superior performance with inverted F-antenna.

The main differences are:
1) Easy of construction, the PIFA is easier
2) Influence of ground planes around it, the PIFA is more susceptible to it,
specially for impedance.
3) Bandwidth, the non-planar has greater bandwidth.
4) PIFA is easier to match, since you can have a CPW transmission line
and use L/C network for matching
