I am currently trying to parameterize the feedline position on my rectangular microstrip patch antenna on HFSS. For reference, here is my design.
I am trying to offset the location of the feedline along the x-axis to optimize the performance. For this, I am trying the parameterize options in HFSS. I have tried setting the range of the x-coordinate from -8 to 8 with a step of 1. The nominal value, ie, location of feedline in the image is at -0.5.
And on validation and simulation, I only get results for -1, 0.5 and 1 while the others have this particular error.
As you can see, only -1, 0 and 1 are simulated. How can I rectify this error?
Thank you for taking the time to read so far.
Hoping for help!
Feeding methods (method for driving power to the antenna) are introduced. The direct feed, the inset feed, the aperture feed and the coupled or indirect feed are presented for microstrip antennas.
