Really? I think if I adjust the size of each patch, it will reduce side lobes... Okay.. Thank you!

Thank you for reply my problem. I am designing my antenna using Hfss11. Im only focus on realized gain to inrease the sidelobe level at phi=90. and main beam is located between 0 and 5 degree. Operating frequency is 26Ghz. Ok. Anyway.. What is the meaning of dolph-chebyshev coefficient...

Series array antenna means series fed antenna. I mis choose the words. I'm not good at english. I'm designing 6x1 series fed rectangular patch antenna. And I want to obtain low side lobe level. But my design result is poor. So, I use dolph-chebyshev array. And, I obtain some...

Hi, all I want to control the power ratio of my series array antenna. I heard there is some relation between width of rectangular patch antenna and power to control the power ratio. I want to know.. Do you know some relation?

Hi :) I am designing 6x1 series fed microstrip rectangular patch antenna by using HFSS. The schematic of the my design is below. This figure is the half of my design for the past analysis. My goal is below. SLL(side lobe level <-25dB) S11(<-20dB) After I design the patch...

thank you for reply :) first, i expanded csc^2(z) in Laurent series and (z-i)^2 = z^2 -2iz -1 after that, multiply Laurent series and z^2-2iz-1 and pull the residues off the z^-1 term. but I wasn't sure this was a good idea. Is this right?

Homework Statement \oint (z-i)^2 \div sin^2(z) gamma : 4+4i, 4-4i, -4+4i, -4-4i rectangluar Homework Equations residue theory The Attempt at a Solution I don't know how to solve this problem. I do my best using taylor series... however it doesn't solve the problem.. Please help...
