  1. ,,, to put 2 of them side by side ,I do not think it's possible...!!!
  2. ,,, these would be the dimensions...!!!
  3. ,,, it is still possible...
  4. ,,,the best, Bester Antenna...
  5. ,,,if you have this type of antenna, please, if possible, give me its dimensions (I don't think it has 14 dBi gain).....!!!
  6. ,,,which antenna are you referring to...!!!!
  7. ,,,on this forum you can find some information...!!!
  8. ,,,it has a length of only 385 mm...!!!
  9. ,,, okay, let's try...!!! ,,,should it be like that....??? ,,, buddy, you know how to work with CST Studio...???
  10. ,,, something like this... PeBac800.cst
  11. ,,,then you don't want my type of antenna patch anymore...??
  12. ,,,,aaaaaa, that's what you want..???
  13. ,,,4 sides,not 5 sides...???
  14. ,,,what do you understand "surrounded by steel on 5 sides"...????
  15. ,,,maybe only with more directors...!!!
  16. ,,,hi buddy...!!! I don't think I have this file anymore, but I will resume the simulation, if you want...!!!
  17. ,,,can someone be interested in something like this///...???
  18. ,,, the antenna is not well designed, it needs a stub...
  19. A new small, low-profile and light-weight helical antenna element was designed for 2,1-2,4GHz-band communications. The novelty of the antenna is that its input impedance matching has been improved by adjusting the copper strip matching stub, while its circular polarization performance has been enhanced by changing the parasitic radiation patch loaded in the front of the antenna.
  20. This is my oldest yagi-patch antenna project which I will try to optimize on the 2.442GHz frequency
  21. ,,,these would be the results... to see the axial ratio in CST, you should look at "Farfields" section in the simulated results... there should be a drop down list after simulating the design. if you click on that drop down list you should be able to see the axial ratio plot... The default plot is in 3D format, if you want to plot it on polar form, you need to right click on a farfield result and select "Far field plot properties", In the "General" tab select "polar" for the "plot type" and choose the values for "Theta" & "Phi" according to the orientation of your design. Then select "apply" to see the results
  22. Here are some quick notes about the parabolic type dish antennas you might find. The actual antenna is a normal half wave dipole with an integrated balun and is located inside the sealed plastic cover. The mesh screen is the reflector which concentrates the RF energy onto the antenna. That is how dish antennas increase the received or transmitted power level. Also, wireless cable service providers frown upon giving away their used dishes as they think you're going to steal cable service.
  23. Hi buddy...!!!! ,,,what version of CST do you have...??? ,,,can you post the CST file..??
  24. 4G antenna BDM-2 is a wave channel with crack initiation, and the delay line is made of sequentially installed disk elements. Compared to the classical antenna BDM , new directional antenna BDM-2 is: More gain; Improved radiation pattern; More stable operating parameters; Greater reliability; Superior mechanical characteristics. Due to the small weight, a small sail and streamlined shapes, the antenna BDM-2 can be used in almost any climatic conditions. And corrosion-resistant materials of the antenna will ensure a long maintenance-free operation even in the marine climate. Specifications 4G/LTE antenna BDM-2: Antenna type Directed Beam width H/V ° 20/20 Frequency range, MHz 2600 MHz Polarization Linear orthogonal Gain, dBi 15-17 DBi depending on frequency of execution The CWS in RAB. the frequency range, not more 1.5 Max. input power,W 50 The weight of the antenna package, gr. 910 Input impedance, Ohm 50 Overall dimensions, mm Ф90 x 500 The operating temperature range, °C -40 .. +60 Performance All-weather, all - Connector (on the case) N-female x2
  25. ,,, yes, increase the diameter of the reflector (not too much) and increase the number of directors..!!!! ,,after a certain number of directors, the gain does not increase so much..!!!
