you could use the aperture coupled feed method and the multilayer method, and the bandwidth could reach 20%.
I have to verify the results of a differential microstrip patch antenna of a research journal for my college project. The antenna consists of dual patches which are electromagnetically coupled (Antenna design attached). The simulated VSWR and gain plot are attached along with the simulated results of the paper. As you can see I am not (...)
hi,i have designed a stacked microstrip patch antenna using ads,but i dont know how to provide the apperture coupled feeding for that.could you please help me with it?
Hello everybody, I'm trying to simulate an aperture coupled patch antenna(rectangular)at the millimeter band with HFSS, i made my 50 ohm feed_line into 30um substrate, and my ground with the aperture above it. First of all, i triyed to simulate with a wave port (sized as hport=6 times substrate height and Wport=5 times feedline width), this give
plz help me out in proximity coupled microstrip patch antenna using HFSS. if u guys have some tutorial on this plz forward me
Hi.. I am designing an aperture coupled metamaterial patch antenna. So through which method i should implement metamaterial i.e. srr or csrr and where to implement it on substrate or patch or ground using cst.
What frequency? What array spacing? (lambda/2?) What sort of feed arrangement did you have in mind for the patches? (probe/aperture coupled/edge fed?) Any phase shifts between the driven elements for beam steering? While all of the above are essential to know from an implementation viewpoint, fundamentally the design of a 1x2 phased array is p
Dear friends, I am trying to design a u-slot aperture coupled patch antenna in millimeter-wave band (about 30 GHz) using CST and according to the picture attached. I have a few problems in the procedure: 1- I can not find "foam" in CST material library so I think I should make a new material myself. But the problem is that only the εr of
hello I want to simulate the aperture coupled micro-strip antenna, and i have the parameters of this antenna, just i want to know how to design waveguide port, i tried to use 3*wf X mt+5*hp:wf is width of feed line,and hp: high of substrate of patch, but for microstrip antenna,you know in this antenna, the feed line and patch are on the (...)
Hi Divya.S Bandwidth can be increased creating more than one resonance. Aperture-coupled patch is a suitable feeding method that allows this. How are you feeding the patch? Other methods are stacked patches and coplanar parasitic elements, among others. Look for chapter 9 of "Microstrip Antenna Design Handbook" by (...)
increase height of patch above ground plane. Doubling the height will double the useful bandwidth. Use of an additional resonator so you get a pass band that looks like an over-critically coupled 2 resonator band pass filter. By using two resonators (that is the antenna element itself and an additional resonator), you can double the useful ban
i have optimise a frequency recofigurable aperture coupled patch antenna with antenna substrate as FR4(K-4.4) having thickness of 0.7mm but i m getting very less bandwidth so how can i increase the resonance bandwidth with these specifications?
Hi i am working on a unit cell of a reflectarray patch antenna with slot coupled to a microstrip. I tested the antenna with a micro strip excitation. Now i need to test it by exciting the antenna using floquet port. So i put master and slave conditions floquet port and then what ? how to proceed after what are the parameters to look at ? sho
What is the criteria to decide on the position and size of waveport in aperture coupled Microstrip patch antenna and linefed microstrip patch antenna???
Hi, I am trying to simulate a aperture coupled patch antenna, i have many problems in design of waveguide port with CST and when the simulation begins, it always been aborted automatelly with the error: The current settings will probably lead to a very long simulation time. You may improve the simulation speed by: 1. check the freq. range a

can some1 help me to know how to obtain the length and width of the feed line in proximity coupled feeding for rectangular microstrip patch antenna.
can some1 help me to know how to obtain the length and width of the feed line in proximity coupled feeding for patch antenna
hello sir, i m designing an aperture coupled microstrip antenna. i have designed it to operate on 2.2 GHz. however, now i want to make it operate on 2.45 Ghz. what are the changes to be made?
how i can design the microstrip feed line using CST microwave for aperture coupled patch antenna
