Increase Gain in 4 element Patch array

Hello every one,

i'm New in Hfss, i'm a student and i want to know how to increase gain of 4 patch microstrip array on hfss ? I have to submit my project to the teacher and now i'm Blocked can anyone help me to improve the Gain of the antenna and specially how to do Bends in the feed network.

Thanks for advance

Use thick and low dielectric substrate material.
Which substrate are you using in this design?

Hello again ,
Dear anilkrpandey thanks for your reply i'm using Rogers RT /Duroid 5880 for my substrate with a dielectric constant 2.2 and with a Height h =0.127mm i'm not sure but i think it's beacause of Bends of my Feed network if you want i can sent you my 4 Patch array in your Email and take a see for the stucture.

Thanks Again

What gain are you getting? What is your target?

You can check out the microwave101 on microstrip bends.

Hello Dear hagster
Thanks for your reply and i can show you my Gain in this picture below. i Want to Create a 4 patch microstrip array which operate with the frequency 60 GHz ( Millimeter wave)
The problème that i can't doing the bends using Hfss despite that i have achieved some of Bends but not all.
As you see at the Patches i realized the Bends but in the Feed network i can't i'm trying to do them.

Hello Dear Hagster, hello to eveyone in the forum,

Can any one tell me how can i do this type of bends using HFSS with easy method and thanks for advance.

Sorry no. My HFSS skills are pretty rusty.

Hello Dear Hagster, No problem we will found a solution.
Thank you for replying
