## Evaluation of PSD for UWB antennas with defined input pulse by use of HFSS.

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 (...)

## Patch array elements feeding position arrangement

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

## millimeter wave antennas

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 (...)

## what are the applications of log periodic antenna??

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 (...)

## Microstrip patch antenna

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 (...)

## Antenna Impedance of RF Modules

Hi dear friends. I've purchased a RF ASK transmitter module and an ASK receiver module in order to build a remote control system. They are WXC810 and PCR1A chinese modules that work at 315MHz frequency. The problem is that the datasheet of module doesn't say anything about the impedance of the antenna that I shoud use (Or maybe I haven't found

## does patch antenna gives omnidirectonal radiation pattern

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

## Bowtie antenna for UWB Applications in HFSS

Hi all, I want to have efficient way of designing a bowtie antenna for uwb applications. Can any body provide me with the tutorial...

## planar phased array antenna

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 (...)

## HFSS 13 antenna design procedure deeded

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

## Rfid antenna design, software,

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 (...)

## Patch antenna design for rfid applications

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 (...)

## How to start learning antenna --- need help

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.

## dimensions for bowtie antenna

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 (...)

## Microwave Transition Design

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 (...)
