  1. ,,, yes, I know this...!!! I would like dimensions of the other antenna, with dipole..!!!
  2. This is a good antenna, you can attach and sizes..!!??

  3. UWB Antenna on PCB

    Admin replied to Admin's topic in Modeling antennas

    ,, or a CST file, more... SMA Conector.cst ,,,with Discrete Port(2) and Waveguide Port(1)
  4. ,,,that would be simulated with SMA connector...
  5. SMA Conector.cst
  6. something like...
  7. you can post here the sizes or possibly the file * cst...???
  8. ,,,you can try to put this sma conector...
  9. yes, it's for good..!!!
  10. Yes, it's possible..but with a VSWR <1.5.!!! A good antenna must to have VSWR<1,2
  11. ,,, why, never say give up...!!!
  12. actually I do not know what makes them,and you try it... 1111.cst
  13. ,,,to better elucidate on Inset Fed Microstrip Patch Antenna....http://www.microwavetools.com/inset-fed-microstrip-patch-antenna/ ,,, and a calculator for it... inset_fed_antenna.exe
  14. I'll try to do it the simulation cst....!!! but anyway, you have to try in the future to work with literary parts(not numbers) in the Parameter List of CST's
  15. Alfred, you're right, I increased the size ...13,92mm at ..14.52mm(13,92+0,6) ,,,I think it must to modify the inset feedding of antenna for a good adaptation line at 50 ohm impedance
  16. I think it's better to try this ...
  17. Alfred, it seems that the antenna is not properly designed, look..

  18. The BEST DIY Antenna for HDTV

    Admin replied to Admin's topic in HF, VHF and UHF

    ,,, and another improved by the addition of two lateral wings ,, but it is the most efficient solution by adding a reflector...

  19. U-slot antenna

    Admin replied to Admin's topic in Antennas for 2.4 GHz band

    ,,,unless if you translated feed point to the left or to the right...!!! You can try...!!!!
  20. Universal irradiator 3G/4G MIMO 2x2 for the parabolic reflector ("dish". F=1920-2680 MHz. Works in the standards LTE2600, DC-HSPA and WIFI 2.4 GHz. Fitted with connectors, N-female. GAIN=9dBi. The feed offset parabolic antenna 2x2 MIMO UMO is designed for use with 3G/4G and WIFI (2.4 GHz) modems/routers, and other devices MIMO 2x2 of the range 1.92-2.68 GHz. Using 2x2 MIMO systems to obtain the maximum speed of data transfer provided by the operator. Advantages of the radiator UMO MIMO 2x2: The irradiator has two connectors, corresponding to orthogonal polarizations of the radiated signal. The original design of the antenna feed provides high isolation between inputs in a wide frequency band. Application a parabolic mirrors of large diameter allows you to gain a much larger antenna than other designs. The irradiator is recommended to use complete with offset short-focus mirrors (F/D=0.5-0.6). Radiating elements of the radiator securely sheltered from rain and aggressions in the plastic housing.
  21. ,,, and a rectangular antenna with circular polarization.. ,, these results ..they are, but results have improved this antenna
  22. Follow,,, this ... ,,, and about it would result with minimal improvements...!!!!
  24. ,,, no, I think it looks like Chinese hoax ... !!! Anyway,,, I think there not exceeds that...
  25. A change in the geometry,,, 16xthree-pole elements
