First of all, I'm no antenna expert. I'm currently trying to extract Power Spectal Density (PSD) of an antenna excited by a well defined pulse in HFSS, to check its performance against FCC mask for UWB indoor applications. The question is: can I have PSD somehow directly from HFSS (...)
There is patch antenna image (i taken it from ) 117286 Usually patch arrays have feeding line coming from one side. for example, all feeding lines can come from bottom side. But on this image we can see that feeding lines also come from top of patc
Hi all, can anybody suggest me any books or articles that focus on different millimeter wave antennas and their respective applications. 60 GHz is the frequency of interest. I am interested in antenna designs which have been or can be used for applications like gigabit WLANs, HD video (...)
It is capable of maintaining a reasonable VSWR match over an extremely wide frequency range. The construction includes elements that progressively change size, yet all couple their energy to the feed line. This makes it useful for things like EMC testing where a signal generator can deliver a wide frequency sweep in one go. Also, for any (...)
Hello Colleague, - I found an accurate equation for Zc in the book "antennas for all applications" by John D. Kraus: Zc= Zo/(√ε r[(W⁄t)+2) 92593 Where: Zc= Characteristic Impedance Zo = Intrinsic impedance = 377Ω ε r = Dielectric constant from your material: I guess (...)
Is that a standard for both "transmitter and receiver" antenna impedance? Is it true for all ASK modules? The modules have an ANT pin that I connect the antenna directly to it. I don't see any special connectors. Or maybe I haven't got what you mean exactly by "connector". How do you intend to connect the anten
Yes, a patch antenna can have omni radiation pattern in Azi and Ele planes. These antennas are used for aerospace applications (as an array), mobile phones use PIFA and can have omni radiation pattern
Hi all, I want to have efficient way of designing a bowtie antenna for uwb applications. Can any body provide me with the tutorial...
I'm trying to design a planar phased array antenna consisting of circular dielectric waveguide for 15.25GHz applications(lattice is skew). i modeled hexagonal unit cell in hfss with master/slave boundary condition and PML. and then i want to see my anten impedance matching in all scan angle is good or no!! floquet port (...)
Hi, could you send me your antenna by HFSS 12 that i have to see your problem. i designed U shaped antenna for UWB applications.. Thanks
Dear all, i am working on designing a spiral rectangular antenna for a tag, but i have a few questions: which software do i use ?? is the antenna normally in the form of a wire ?? do i need to buy a chip for the antenna to form the (...)
Balanis is a profound text book, and should be sufficient to find a basic answer to nearly all antenna related questions. As you say, microstrip antennas are too large, I wonder if you possibly try to achieve something unreasonable. What's your frequency of interest? Patch antennas are suitable for 860 (...)
Thanks, my problem with electromagnetism is limited time. I will try to get antennas for all applications. Without understanding Electromagnetism, you can not understand antenna theory.. Get a solid background about Electromagnetism first and then read those books about antennas.
If you have a design that is based on air, and you put it on PCB, the size must reduce somewhat to compensate for the reduces propagation speed because of the dielectric properties of the PCB material. If the thickness of the dielectric is far below the size of the antenna (for example a 900 MHz bowtie on 1.5 mm FR4, you should think of a (...)
Hello all folks, Please provide links to these books 1) Microwave Transition Design By Izadian, Jamal S. (Author), Izadian, Shahin M. (Joint Author) --- Very Important!! 2) Novel Technologies for Microwave and Millimeter-Wave applications Kiang, Jean-Fu (Ed.) 3) Microstrip and Printed antenna Design (...)
i don't why addition a slot on patch antenna can compressing scattering parametter S11. Can you help me explain this problem ?
Dears, We know that UWB antenna have bandwidth (3.3GHZ - 10.6 GHZ) but how make multiband for UWB wireless applications? I attached paper that indicates types of multiband antennas. Thanks to all.
Dears, We know that UWB antenna have bandwidth (3.3GHZ - 10.6 GHZ) but how make multiband for UWB wireless applications? I attached papers that indicates types of multiband antennas. let's discuss it together to reach good result. Thanks to all.
for basic antenna theory, I recommend Stutzman, Thiele: antenna Theory and Design
If you are a student, Balanis is good. You can use modern antenna design 2nd Ed. THOMAS A. MILLIGAN for more dettail on some antennas.
Hi to all, I am going to do project. It is designing of vivaldi antenna for 2 - 6 GHz frequency range on FR4 (Er = 4.4) substrate with CST MS. Could anyone tell me about the informations or websites or books. Thank you for advices.
Dear all, I'm trying to design a planar phased array antenna for mm wave applications (60GHz), and looking for any helpful information (papers, hfss files etc.) Does anybody have a HFSS tutorial for designing microstrip antenna/arrays? Best Regards
More often circular or rectangular microstrip patch antennas will be used depending upon the type of polarisation required. some of them used printed dipoles also...........
hi, i hv designed a patch antenna for circular polarization. The thing is the antenna has axial ratio of 0.82 dB for phi=80 degrees & theta=330 degrees. The resonating frequency is at 4.43 GHz and all other parameters are very nice. Can we call this antenna as circular (...)
"Reflection Phase Characterizations of the EBG Ground Plane for Low Profile Wire antenna applications" Fan Yang , and Yahya Rahmat-Samii
A good introductory book is " Smart antennas for Wireless Communications: Is-95 and Third Generation Cdma applications " by Rapaport
Hi all. After 5 years I have shifted away from bluetooth and onto DAB radio. Is anybody else out there designing boards for DAB applications for small handheld MP3 players. I am interested to find out if there are any parts to avoid using for volume manufacture in China. Do I use a (...)
hi i think antennas:for all applications . third edition by John D.Kraus and Ronald J. Marhefka will help a lot ,really good book,enjoy
Hi you could look at chapter 8 in the book, RF MEMS and Their applications by Vijay K. Varadan K.J. Vinoy K.A. Jose It is available on the board some where. I certainly feel that you can look at antennas for Software defined radios. That is a good research area. -svarun
The AX-31B antenna is a compact VHF/UHF directional antenna with an in-built amplifier, which provides a low-cost alternative to conventional VHF/UHF antennas (for example discones), especially for indoor professional and amateur applications.
A advance book by the name of antenna Theory (Analysis and design ) By Balanis antennas for all applications is a very good book as well.
