hello everybody,
i am supposed to design a rectangular microstrip patch antenna for 2GHz and 2.5GHz with double inset feed. The patch length should be the resonating length for 2GHz and the width for 2.5 GHz. When i do it for individual frequency it is ok. but whenever i am using two inset feeds(one along length for 2 GHz and the other along width for 2.5 GHz) the frequencies shifts about 0.3-0.5 GHz to the origin. I have got no idea how to implement double inset feed. the project needs to be completed in 1 week.
i am using IE3D from Zealand for simulation.
i have searched the internet but i could not find a single example of double inset feed.
Please help.
Thank you in advance.
