thanks Azulykit..i get all useful formula..but there is a small issue. when i am trying to design there are two condition z0 when w/h <1 or w/h>1...the question how i can investigate this while i dont have line width w while i have zo=50 ohm
hello
i am working on microstrip antenna array for first time...i have problem with designing corporate feed network for 4-patch array...
this problem is how to calculate the width w and length L of each section (z0=50 ohms) and for (z0=70.7 and 100 ohms) also the quarter wave transform.
for...
thanks Dave
there is line of sight, which means there is no vegetation or hill ridges.
is this means that 28 dbi parabolic antenna can solve the problem of receiving wimax signal or coverage from the tower.
hello
my question related to high gain Parabolic Antenna 28dbi for wimax coverage reception
where my house is far from nearest wimax antenna (Tower) approximately 10 km..and i dont have wimax signal at all...i tried 24 dbi and i get into setting page that is 198.162.2.1 but it said that some...
hi
finally i finish my simulation and fabrication of dual band microstrip antenna for wimax application
my question is how to compare S11 plot of hfss (simulation ) and S11 of vector analyzer (measured ) on the same graph or plot.
hi every one
i had finished all my calculation in my Msc thesis it was in microstrip antenna design,
my question related to a problem faced me now at the end of my work
where the last chapter related to antenna fabrication and its measurement
but the problem that in hfss simulation i get the...
hi every body
during my thesis
i did my simulation for wimax dualband microstrip antenna with hfss... and i get my goals 2.5 and 5 ghz
but the problem appears during fabrication
where other bands appears and the desired band dont appear
for example i get 1.7 3.4 and 5.15ghz
plz tell me the...
hi everybody
i finished my design for wimax antenna for 2.5 and 5 ghz...
in fabrication i faced problem about the substrate height
the substrate fr4 with height of -1 mm
what is the meaning of - sign here
where if the height changed to +1 mm the result changes for s11
here attached figure
i designed my antenna microstrip patch ....i get the desired values of s11 vswr and gain....but when i make export this file to GDSII ...and after import this file to awr its ok in shape....but the results are totally different....plz help me whats goes in.
hello every one
i finish my design for wimax dual band microstrip antenna on hfss ...because of the hfss version is cracked one...and i have licensed version of AWR (Microwave office)...i am looking for a way to transfer or copy this design from hfss to AWR.
thanks alot.
