hello everyone anyone have any paper for folded dipole antenna please send to me i am need to study that paper to do my project. hope i can get that paper that relate for GSM BAND frequency 880 960mhz and 1710-2170mhz
Hi, I have designed a folded dipole antenna 200 GHz. I have increased the number of turn and checked the S11 parameter and expecting a narrow bandwidth. But I am not getting expected result. However, Impedance curve seems ok. Can anyone tell me please which parameter contributing to this problem and how ca I solve this provlem? Thanks (...)
Dear all I have to design folded dipole antenna in ADS, can any one provide ma dipole antenna designing manual/tutorial???
Hi, I am new to ADS layout simulation. I have simulated the folded dipole microstrip antenna suggested by TI(Texas Instruments) for transreceiver chip CC2500 to work for 2.4GHz frequency in ADS (whose datasheet is attached) but I am not getting the desired output. I have attached the method that I followed with the datasheets (...)
Hi: I think one more reason people use folded dipole is for matching. A typical dipole antenna with normal radius has a Z = R + j X = 75 ohms at the resoance defined as jX = 0. A folded dipole's impedance will be about 4 times as big. It is close to 300 ohms and that is why many old TV (...)

Hi everyone, im trying to design a folded dipole antenna in cst. In the feed center there are a horizental arm and vertical arm i want to coonect them by discrete port but it gives me an error that the discrete port is inside the perfect conducting material. i checked the locations many time. Can anyone help me with this,plz thanx
Deborah, Please see attached file. This was a Yagi-Uda antenna array I put together for optimization but never got around to it. The Yagi_uda is driven by a folded dipole antenna which was optimized in its own design in the file for the given frequency. Have Fun
Hi jsp, r u talking abt a folded dipole? Cheers, Element7k i have some question about the dipole antenna design suppose u have tx output 50ohm and matching 50 to 300 at that point two lamda/4 line then what should be the imp of the elements of just for electrical length it should be quarter wave thanks in (...)

hi, my design is to match a folded dipole to a chipcon-based differential RF ports (86.5+j43) since the radiation resistance of a folded dipole is about 300 ohms, then i need to match this to a differential line of 86.5. my question is: is it possible for me to use a coplanar line designed with an (...)
Hi everyone, would anyone tell me why we have VSWR variation if we change length of a folded dipole antenna... if u have any useful paper regarding this issue, i'll be very thankful thanks in advance
i have been made microstrip folded dipole antena for TV reception, it very good for reception.. the method to make it only trial and error used microwave office.. i not found the formula to syntesis the width or the length.... i assume only when it need more bandwith and lower frequency it need more length so i make it paralel... ma
I'm simulating a multiple fold dipole antenna for 200 GHz (lamda_g = 597.2 um). The antenna is folded 4 times (has 5 poles) for very high impedance. The antenna width and arm spacing is 0.02*lamda_g. The feed gap is 24.5 um. So I made the wave-port 24.5 by (s + w) um. Is this acceptable? Or is a lumped port (...)
Hi, I newbie in antenna area. Currently, I'm trying to design a folded dipole antenna. Thus, I need some ideas on how to design that antenna such the dimensions, length and others. Please help me. Thanks.
I was reading about this Yagi Uda antenna and I came across this-- "If the distance between driven and parasitic element is decreased the it will load the driven element, irrespective of its length. Thus input impedance at the input terminals of driven element reduces. This is why a folded dipole is invariably used as driven element so that r
i desgin folded dipole for FM band using cable RG11 which is 75 ohms is no problem SWR is less than 2 but i trying to bulding with 50 ohms cable which i got SWR greater than 2.5 if any one have ideas how to improve it thxs
and another kind of small demantional and effective antenna is "folded dipole antenna" if you fold a dipole antenna once its ampedance is muliply to 4 and if you fold it n time it ampedance is squr n times grow
Hello! There exists many antennas that differs in their radiating resistance. But can we say that a 50 ohms p@tch antenna is less sensitive to e.g. the hand than a 300 ohms folded dipole antenna? To enlarge the issue, what antenna characteristic (-10dB bandwidth, environment (...)
I am a newbie in using HFSS. Could anyone guide me how to simulate a printed dipole antenna in HFSS. My target resonant frequency is 900MHz. It is the best if someone has a sample file. My points now maybe is not enough, hence my email address is Thank you.
