Hi My antenna is an ultra wide band (3.1-10.6GHz) hfss I gave solution frequency as 10.6GHz and drew radiation box corresponding to 10.6GHz. Is it correct? Please help....
Hello All, In CST MWS, I'm using a square pulse, current signal as an excitation signal sent from Design Studio to Microwave Studio using the co-simulation feature. I am interested in the transient behavior of a wide-band antenna after receiving such a square pulse. I was hoping to see a damped sinusoidal response with time after the (...)
In the past I used a dual dodecahedral antenna for wide band. For microwave, these days people are using Fractal types.
Hi Friends, I am designing log periodic dipole antenna in ADS but i am not getting exact results over the wide band from 2GHz to 10GHz, Can anybody help me with designing values and images and i have one more doubt like whether is it possible to design LPDA in ADS why because normally an LPDA antenna doesn't need any (...)
How to de-couple feed cable for measurements of electrically small wide band antenna? I normally use bazooka-type coaxial balun to decouple feed cable. In this project bandwidth is large (0.85 - 2.1 GHz) and bazooka balun does not have the required bandwidth to cover the band. Plus (...)
Hi guys I'm working in a integrated feeding system for a type of spiral antenna my antenna work very well , I have a return loss better than -10dB in 2-12 GHz my Balun work very well too but when I connect them together my results are so bad and I dont have a wide band Can anyone help me ?
Hello, i am designing a microstrip dipole on the frequency between 900 Mhz and 2200 Mhz . i did something about it in Hfss with lumped ports but i should realize it physically.And when i did it with lumped ports it have not a omnidirectional pattern . so what can be the problem fot this? i didnt use a balun is it a problem for this? thanks
Hi Every One... What is the Difference between wide band antenna and narrow band antenna? what range of frequency will be called as narrow band and what range for wide band?
hi friends, a new issue to be discussed. I was reading about ultra wide band radar sensors. and found a nice block diagram as follow. 86364 the simplest thing i know is that an antenna is connected to transmitter side, transmits signals and a receiving antenna receive the signal... what is the need of a delay line in th
Hello I working on the attached paper and i want to know to the reason behind the enhanced bandwidth. What happened to it using the L shaped ground plane that helped to have wide band characteristic. with best regards. Vishal
It also depends on the kind of the antenna. Some antennas have a small band while others are very wide band antennas, for example antennas used in cell phones or cars. If you use an antenna that covers the frequency band you need this should (...)
In every paper they have used FR-4 as the dielectric substrate for the Ultra wide band antenna. Could anyone explain why have they gone for that choice? This is the standard material for PCB design, and for cost optimization, people try to integrate the antenna onto the same standard PCB as the circuit.
I'm going to use a dipole antenna for 300-900MHz application... Do you know is there any available antenna in the market... I designed one but Its S11 is not as well as I expect... I prefer a patch antenna...

Dear Friends, I'm new to this Forum. I find this very interesting and helpful. Now I want your valuable suggestions for my small project. Here I attached the circuit schematic of an analog wide-band beam steering circuit. I want to steer my antenna primary beam(8 degrees) by certain angle by introducing the cable length equal to angle of (...)
THere may be considerable phase shift thru this wide dual bands and not possible. I assume you have done something like this already
You apparently never read antenna basics. Please do. UWB utilizes very wide bandwidth, so resonant antennas are not suitable for it.
Hello, You may try "Compact & Broadband Microstrip antennas", by K. Wong. Regarding "design equations"; If you want to design something new, innovative, you may need to do everything yourself. Note that small, high gain and wide band don't go together.
you can use this Ultra wide band
I design ultra wide band micro strip antenna using HFSS , when i make to it export *.sm3 to run it on CST i get different result can anyone help me it's my thesis in mater thanks all :sad:
Hi All, I'm currently have designed a UWB antenna where UWB stands for (ultra wide band). The problem is that my simulation for retrun loss doesn't get with the desired results. i will attach my result and the paper result if any one can help please i will also attach the paper 65181
Hello, You should design the feed alone and put two ports, one each at either side. Simulate for wide frequency band and look for S - parameters. They should be within the specified limits. As for physical dimensions for coaxial feed, you may look on internet for common SMA connector layouts. Most common SMA use PTFE as dielectric to get 50 ohm im

Hi all, I'm a student currently doing my undergrad studies in Singapore. Is there a design to increase the bandwidth of the Quasi-Yagi antenna without decreasing too much of its directional gain? Thank you Jason :)
Dear all, I am designing a deferential feeding antenna. A wide band 180 deg power divider is used to transform a single-ended signal to two deferential signals which are anti-phase with each other. and the two deferential signals are fed into the antenna via two coaxial ports. I used HFSS to get deferential (...)
Hi sir ferdows, my lecturer decided to apply ultra-wideband antenna technique in UHF television frequency range, and pardon me to ask if you have any reference about Ultra-wideband antenna fundamental itself, because i'm still confused about the difference of non-ultra (...)
Just another idea. U-shape slot antenna can get wide bandwidth.
I have never design so wide band ANT. you can find spiral materails as reference.
As a first remark, induction loops for hearing assistance are in fact transmitting unmodulated audio signals, so they are wide band rather than tuned circuits. There are however other induction loop systems using modulation. To characterize the transmission system, you would want to measure magnetic field strength. A loop antenna, (...)

Try PICA antenna - Planar Inverted Cone antenna. It's easy to generate in CST MWS and you can easilly match it to 50ohms. Or you can use some improved bow tie antennas too - see: Qu, ShiWei; Rhua, Cheng-Li - Planar bow-tie antenna embedded in circular aperture within conductive frame. However, everything depends on (...)
