Designing L PROBE Feed Microstrip Patch Antenna

[goli]

Hi, I am an electrical engineering student and i am designing a L probe feed Microstrip patch antenna.Can anyone help me in the steps involved in designing and Simulating the desing using IE3D.

Thanks

Hi, goli:

I am not sure how the L-shaped probe looks like. However, following is an example to show you the similar case. Assume you try to build a probe feed like the following.

side-view

-------patch----------d------------------------
|
b----c
|
------gnd-------a--------------------------------

When you can do is:
1. Build the patch.
2. Build the gnd if it is finite.
3. Enter 4 vertices (a,b,c,d) on IE3D/MGRID.
4. Select Adv Edit->Build Wire Path. Please choose to build a connection at "d" while you can build a port at "a".

The above scheme works for all wire antennas and probe-fed antennas. This scheme is extremely useful for wire antennas with lumped elements. You can build ports at the locations of the vertices if you want. Regards.
