Wilkinson power divider design using CST

[Fhasan]

Hi all,

i am postgraduate student and currently being ask from my lecture to design wilkinson power divider using CST. I am still new with CST environment and if there anybody have toturial or tour guide on using CST it would be appreciate if you guys can post here. The design specification and requirement are as follows:-

Types of power divider : Wilkinson power divider
Number of section: 2
Multisection quarterwave transformer: Binomial
Centre frequency: 2.4GHz
Power division: 3 db

Requirement:
Simulate the circuit using CST for the above power divider in stripline technology. Substrate with Er=3.38 has to be used in the design and the design must be at least 10 db isolation. Appreciate ur advice and time. Thanks

Hi Fhasan,

Since you are new to CST, it is better to go through some CST tutorials first before jumping in to wilkinson design.

I found this excellent CST tutorial for beginners from a Hong Kong uni.**broken link removed**

For the wilkinson design problem, better to go through a little bit about single section wilkinsons from David Pozar's Microwave Engineering book or any other microwave text book.
For multisection designs Microwave101 **broken link removed** will be useful.

Since you are a postgrad student you may need some theories too. for that purpose refer to some papers such as:
[1] E. Wilkinson, “An N-Way Hybrid Power Divider,” Microwave Theory and Techniques, IRE Transactions on, vol. 8, no. 1, pp. 116-118, 1960.
[2] L. Parad and R. Moynihan, “Split-Tee Power Divider,” Microwave Theory and Techniques, IEEE Transactions on, vol. 13, no. 1, pp. 91-95, 1965.
[3] S. Cohn, “A Class of Broadband Three-Port TEM-Mode Hybrids,” Microwave Theory and Techniques, IEEE Transactions on, vol. 19, no. 2, pp. 110-116, 1968.

hope this will be useful.

I searched for [1] E. Wilkinson, “An N-Way Hybrid Power Divider" ,but didn't find link to download.
Please show me if you have.
Thanks very much!
