mrf24j40

Hello everybody,

I'm a newbie in RF design and I want to simulate the Zigbee antenne from the microchip MRF24j40 Zigbee Module in HFSS. Here is the link to the datasheet.
hXXp://www.microchip.com/wwwproducts/Devices.aspx?dDocName=en535967

Now I have a Problem with the design of the of the Ground plane and the Port of the Antenna. I think microchip used a lumped port, but every try to design a port failed.


Have someone a Idea in which forme the antenna have to be simulated?

Greetings
Stephan

zigbee antenne

Hello

I started anther try, with a inverted F antenna, and here is the same problem. I cant set the port correct.
I dont understand why the design doesn't work. The Antennas in this thread are very similar.
Can someone take a lokk at my Antenna?
