hi all
can anybody provide me with the entire procedure for rf planning of a cdma2000 network....starting from the begining..em doing job in cdma2000 company...want to learn about the rf planning as well ...like how to design a network and implemnt it and testing and optimizing it...can anyone...
difference between gsm and gprs
Hi all
please let me know the difference in these for wireless systems......and please also notify the advancements made in respect to the other or older techniques....like GPRS has a better modulation tech than the GSM, but i actualy dont realy know of...
hey thanx buddy......but i was wondering that if my uplink and down link lets say is the same frequency range, then would it be possible for this amplifier to work simultaneously to receive and transmit. I mean as it is a half duplex so it cant receive and transmit at the same time, so how is it...
hi all
i am presently workig on my WiFi project for its practical implementation. So i am facing a real problem in selecting an amplifier for my base station as it should TX and RX simultaneously.......Is this possible for......as the amplifiers available in the market is bi-directional and is...
patch antenna s11
hi please help me in this......i have designed a microstrip printed dipole antenna that can resonate over multiple frequencies....but with one of the resonating frequency the refflection losses are at -9dB....i tried so much to achieve at -10dB but i just cant do so.....so i...
hi there...
you can simply view the hfss version 9 or 10 book as it has a simple probe feed patch antenna.....and yes it is certain that patch antennas are narrowband limited but there are different techniques for making it a broad band.....you can either make it multilayer but as that is not...
no there is just a standard easy method for its design....just view the hfss book and see the example of the probe feed in chapter 5...but differ the calculations with respect to your own desired frequency and thats it
patch antenna array design in cst
well i am not sure of your problem......as i havent seen your design.....but there must be some problem with your excitation and the air box......wel i have just recently designed a patch antenna of 1.6 GHz that operates quit much precisely.....
but the thing...
patch antenna vs dipole
what i meant was a patch antenna to be altered into a shape of dipole with two arms....actualy it is a patch antenna but in the shape of a dipole....resonating at various frequencies.....and PIFA is used for mobile applications ...but i am designing it for base...
antenna array hfss
oye nabeel its arsalan here....
yar tum log sir k pass vacatioins mein gaye ho kya.....kam kr rahey ho chutiyon mein ......tel me ....coz i didnt go.....me scared k sir ab bolein gain
Re: Spatial Diversity
hi on1...
i am also trying for such a mimo antenna...please can u help me in this too with the documents that you are actualy following ....so that i can also consider the same documents....as i havent started doing my project....please help
dipole patch antenna
hi all...
please help me with my project of multi-band antenna....i have already designed a microstrip patch antenna at 1.6GHz...now my task is to design a multi band printed dipole patch antenna by using a technique of cutting the patch in form of a dipole...but i just...
