Dear all
I am trying to excite the dominant mode "TE 11" as it have the best radiation pattern. the position for the coax-cable is supposed to touch the patch at the center of patch to have the best current and magnetic field distribution. the problem is when the feeder positioned at this place...
hey guys i have designed the required coax with it's inner split. the problem is when i run the design i got nothing, a validation check is made and everything is correct. when it start simulate it run 2 passes and solve at 3 or 4 frequencies. i set the number of passes to 8 and the maximum...
i guess that what is needed is a way in which only one coax-cable is needed and the inner of this cable is split into two conductors located at the position of the two coax-cables inner
Hello
I am working on an equilateral triangular patch antenna, and i have finished the design and the simulation using HFSS, and the result were impressive. The patch is excited using two in-phase coaxial cable. the question is how i can hook these cables together.
Best regards
hello
i have the following designs for corrugated rectangular waveguides which suppose to work as filter, and i need to plot the S11, the problem is the corrugation of the waveguide is controlled by a parameter delta, and when the value of this parameter s below 0.06 the filter response act in...
hey there
i have the following model. the sidewall of the waveguide are representation of the equation
a*delta*sin((2*pi/lambda)*_u) , a+a*delta*sin((2*pi/lambda)*_u+theta) , where a = 7.5cm , lambda = 6.708 cm , theta and delta are varied (delta 0.01-0.1 ,theta 0-pi).
the problem is when...
hi
i am designing a wave guide whose side walls are sinusoidal corrugated. the corrugation of the walls depend on several parameter parameter, one is called delta which supposed to be very small. i design a matlab code that generate the same result of hfss but only for small values of delta...
