Hi I'm working on designing unequal power Wilkinson power divider. I need to implement a 295-ohm microstrip line. The problem is that it's not practical to implement. I found two main techniques to increase microstrip/stripline impedance. 1- using offset double-sided parallel strip line 2- using (...)
Cheap X-band motion sensors such as door openers use separate patch antennas for TX and RX path. It is usually justified by the need of high sensivity, which is obtained by decreasing LO leakage. But as we know such sensors are pretty narrowband, and use only a little bandwidth of few KHz. Please comment on this idea: what if we use microstrip
hi, iam doing project on wilkinson power divider and going to fabricate it in microstrip.i have found out length and width of quarter wave transmission line.but to represent transmission line in circular form i need to know radius formula.i have searched for formula but couldnt find out the right one.
If sensor or transceiver have separate transmit and receive antennas. Where does that additional sensitivity comes from? Assume we have single antenna. If we want to do it without additional microstrip structures, most simple way to do mixing is to put 3-port tee power divider. First port - LO input, second port - sing
Hi, I want to fabricate the power divider and I want to know what is the maximum impedance( or minimum width) in microstrip line that can be fabricated? I use the Taconic TLX-8 substrate with dielectric constant 2.55, thickness 1.575 mm, and loss tangent 0.002 and the center frequency is 1GHz.
Setup: 1) PCB board with two parallel microstrip lines connected to power divider from one side and to two identical diode mixers from other side. One of lines have a gap for common source FET placement. Before placement gap is soldered with copper foil piece for calibration purposes. 2) Frequency generator for freq
Hi All, I'm interested in designing an edge-fed micostrip antenna array, where I would have to use power-dividers to split the input power equally to both the arms/patches. Now the question is can anyone suggest what type of power divider I must use. Is it basic t-junction, quarter-wave matched t-junction (...)
1. Can we obtain higher Signal to noise raitio, if each patch on RX antenna have separate mixer? For example, we have 4 x 4 patch antenna, and each patch have separate mixer (16 mixers, power divider for LO to provide 16 LO channels) 2. Is it feasible to make two-patch antenna, wich radiates not perpendicular to the substrate. For example, radia
Hello all , i am a starter in HFSS . I have only simulated a waveguide and a microstrip line so far. I need to design a power divider with mlines in hfss but i do not know how to represent the cables or the resistance that i have. Any help will be appreciated . I am uploading my exact model created in ADS. Thanks in advance105413
I'm designing a 2-1 way Wilkinson power (5.5 GHz)divider with Z0=50Ω in HFSS on a FR4 substrate. The E-field simulation shows low magnitudes. What could cause this issue? Could the waveport2 have influence on wp3 because they're too close to each other or maybe the dimensions of the divider are wrong? 99647
Hi I see your point. A Wilkinson divider has match at all ports and equal power split. However you need a 100ohm resistor to make the matching. Many patch antennas are just made on a single PCB without SMD assembly. This is cheap and easy to fabricate. But you are right that it is not the same. If you analyse the Wilkinson without the isolation
Hi, I am designing a 3 element linear antenna with 1:3 power divider network for feeding. But the length of the microstrip line to the center element differs from other two elements because all three elements are in a single row, so there is a phase variation to the center element compared to other two elements. I tried to increase the (...)
Hi, I am designing an equal split wilkinson power divider working at 13GHz in ads. When i add a MTEE to it, the s-parameter all goes wrong. I think i may have used the MTEE in a wrong way. Could someone help me with that? Attached are the schametic and s-parameter simulation results :roll::roll: Thanks so much.
Hello everyone, I would like to design power divider or power splitter up to 40 GHz using microstrip lines without resistors (I have found many design with this resistor but I do not want to use it) ,my substrate is LTCC 9K7 (Eps:7.1 Loss: 0.001). Can you give me an advice which of many ways how to do is the best to (...)
hi I want to design a divider SIW 3dB antenna feed usin CST as shown in figure below: 1.Can anyone help me? 2.The length of the line in determining the characteristic impedance is important ? Thanks
Hi, It should be in 2x array form. First, i think you should design the antennas individually according to your desired frequency and then combine them both using a power divider. You can refer to Balanis book or any other microstrip patch antenna books for further research on microstrip patches and on how to design them. (...)
how can i used ansoft designer to design microstrip antenna and t-junction power divider. help
For example, we have 5Ghz oscillator, output goes through microstrip to power divider, splitted to two microstrips. microstrip lenghts choosen to provide 180 deg phase shift. Each microstrip equipped with SMD circulator, that prevents unwanted direction. Then we put power (...)
Sure is it possible, but does it make sense? For the array, why do you want multiple coax feeds with power divider at coax level, instead of a simple divider network in microstrip?
hello every one, i am designing a wilkinson power divider in ADS momentum, so to place a resister between the two output arm i draw a microstip line from each arm. when i insert port at the end of these microstrip lines, and trying to define the type of ports i get this message " Port P4 cannot be associated with port number 5. If they (...)
