Dear Prakash33,

there is a formula
please explain me...i am highly obliged u if u explain me.
thank you sir.
 

hello. im new here. i have to design rectangular patch antenna by coaxial feed for 8 layers of LTCC. here is my specs.

ground and patch = copper annealed
patch =12.35mm x 16.14mm
ground and substrate= 24.7mm x 28.49mm
substrate = ferro A6S
inner/outer conductor = copper
radius inner conductor = 0.55mm
radius outer conductor = 2.0mm

i tried to design for the first layer of LTCC. there is no error and the simulation is done, but why my return loss graph look so weird? anyone can help me and check my simulation? this is my final year project.. tq..
 

Please share your design file in order to take a look.
 

here is my design for 1 layer and 8 layers. hope anyone can check my design and make a correction. really appreciate your help. thanks
