Finding dimensions of a broadband microstrip patch antenna

[Richa Kala]

I want to design a microstrip patch antenna having high bandwidth. Please tell me what will be the accurate dimensions for such antenna. I want to design it with the aid of HFSS . Is there any file which already has the designed broadband antenna? Please attach the file with answer

Hi,
You can find the dimensions for the microstrip antenna in Balanis book Antenna theory and design, in chapter 14. There you will find the formulas for calculating the patch width and length. You have to know of course the resonant frequency, the dielectric constant and the substrate height.

And another thing....if you want to improve..the bandwidth you have to cover with substrate with a superstrate....since the bandwidth is larger as the substrate is thicker, but this may excite some high order modes and some surface waves will travel, which may cause the radiation pattern degradation....Hope it helps.

Hi,

Use this link to get the dimensions of patch antenna: https://www.emtalk.com/mpacalc.php
For broad bandwidth you have to do some modifications in the str. like some slot or cut.....You go through book of ramesh garg for this or u can take help of papers also.

That link is really very-2 helpful. Can u please tell me where can I find the Ramesh Garg ebook..

 

[smritigarg127]

you can get form net or go to your college library,, and u can get any book on microstrip antenna design....

hi .how to design fractal antenna in hfss 13 ,please help me with a step by step procedure

Although you cannot export to HFSS you could consider using Antenna Magus to design your antenna and then you can use these dimensions in HFSS and optimize.
