a signal in the 3.1 GHz to 10.6 GHz frequency range does not have a prayer of penetrating the rib cage and flesh to the depth of the heart. You might want to rethink your approach, maybe use a sub 1 GHz impulse? Otherwise you will just be seeing the skin of the chest moving, and the signal from the heart itself will be so small you will not see i
Hey guys,I am new here,from Turkei. I and my 3 friends will develop a simple GPR radar for our graduation project. *We are going to use 1 Ghz bow tie antennas *is going to transmit pulse signal *are going to detect only whether there is a metal or not under the ground *then we are going to do data collecting interface to simula
Glass has a permittivity of around 4 , the same as paper and circuit board material. Being a good insulator, it will not affect the conducted field at 1MHz however charges may accumulate on contaminated air or surfaces which may result in a partial discharge in a tiny gap < 300Vpp, so keep it clean. Light weight gasses may also reduce the diele
In IE3D, I have a feed structure on one layer, with a via penetrating an infinite ground plane to feed an antenna on a second layer on the opposite side. As far as I understand, there are two methods of modelling the effects of the aperture or void in the ground plane through which the feed/via passes, but do not know how to physically model
hi, can a TE10 mode pyramidal horn antenna be used for ground penetrating radar applications?
Hi, for the control distance you can use UHF products, but due to UHF's feature (not good at penetrating substance), people should swip the card consciously. someone use uhf for attendance people wear card like a badge. More details of products Shenzhen New Force Communication Technology Co., Ltd For LF and HF t
hi for simulation in hfss and design of antipodal u have some way draw by tool or give the equation to hfss for more information about antipodal u can read chapter 5 of Broadband Planar Antennas Design and Applications by Zhi Ning Chen and Michael Y. W. Chia and u can download a thesis by topic of UWB-Antennas for Wall penetrating Radar Systems if
I need a power amplifier circuit for (Ground penetrating Radar) project, i have a Pulse generator & Crystal osc. with freq.=60Mhz and Multiplier in my project. I need power amplifier to increasing power before transmitting it through Antenna
Hi all, I'm new to antenna design, however, am trying to design an antenna for ground penetrating radar. I would like to use a bow-tie antenna for its wide band capabilities, however, I'm strugling with the overall concept. Firstly, would a microstrip antenna be reccomended, condsidering the narrow bandwidth which is associated with them. If so, ho
I would look at antennas that the UWB guys are using (vivaldi, etc). I did a low frequency (<1 GHz) ground penetrating pulse radar antenna with just an open-top microstrip structure, but with a very wide strip width (similar to what you would find in a GTEM cell), and it seemed to work well. The far end was terminated in a number of chip resistor
Hi all, Recently I have a project for my Master Thesis. The project is how to simulate the model of ground penetrating radar (GPR) using SystemVue. I face the problem to modeling the antenna (Tx and Rx) and channel (soil). Does anyone have experience with Systemvue? What is the best model for antenna and channel of GPR? I have the idea that i

i need fdtd software for ground penetrating radar antenna design
Dear friend , Please give to me interesting "PRO" Dedector and penetrating radar projects address. Sincerely.
penetration power increase with the increase in frequency? does penetration power depend on frequency? plz i need a detail answer i dont think per skin effect,penetrating power os any signal into the conductor will decrease if it's frequency increases.... if your having proof means post it ..will be discuss
You are going to need at least 50kV for penetrating a BGA and up to 1mA of current. Most TV flyback only produce up to 30kV. I previously worked at an x-ray tube company here in the US. You can use a CCD camera but you need some material to coat the lens so that when x-rays hit it, it illuminates the material. You can find some inexpensive Image In
i want to know the theory of calculating depth of water table using ground penetrating radar Added after 1 minutes: sorry..........its depth of ground water
Hi zin, interesting antenna. I noticed that they have used open quote i.e. 'Obstruction penetrating' in their brochure. So I think they could just be referring to some antenna diversity/polarisation method. Cheers, Element7k
