Hello Everyone,
I am doing a project which involves Butler Matrix feed. As i was designing the feed i encountered that the slope at which the phase v/s frequency plot changes varied with ports. As such the phase difference between ports was not remaining constant wrt frequency. When i tried with two simple microstrip lines of different lengths (45 deg phase difference) but same width i still got varying phase difference. I cannot figure out why this is happening. I have attached the screenshots for reference.
I am using IE3D v14.Please Help.
