  1. In this paper, we design and analyze a dual-band rectangular patch antenna with slotted patch,patch and ground plane for 2.5 GHz and 5.2 GHz communications.
  2. ,,,,and this would be a wider band antenna with overall dimensions of 240x240 mm
  3. ,,,,yes, there are many types of antennas here...https://qsl.net/va3iul/Antenna/Printed_and_Microstrip_Antennas/Design_Ideas_for_Printed_and_Microstrip_Antennas.htm
  4. ,,,maybe 1800-2100 MHz...!!!
  5. ,,,you can try it...??
  6. ,,,take it... stella-5.cst
  7. I took over the redesign of this antenna and I came up with this version...
  8. ,,,the antenna looks very good but it would be interesting to see its feed points (inside)...!!!
  9. The high quality Patch antenna for 5.8GHz receiver. Can increase the range of 5.8GHz transmitter This 5.8GHz Right-Hand (RHCP) Circular Polarized patch antenna was custom-designed for the FPV market. Light enough to be mounted directly onto an FPV headset including the FatShark Goggle system or Uno and Duo FPV receivers. With a much wider beam than it's 13dBi cousin, it easily has double the range of a standard SpiroNET Omni antenna. Specs: Circular Polarization: Right-Hand Band: 5.8GHz ISM Gain: 8dBi Beam width: -3dB at +/- 45 degrees (H + V) (90 degree total) F/B Ratio: >356dB VSWR: < 1:1.35 at 5800MHz Impedance: 50 ohms Weight: 7g
  10. ,,,it is easier to solder a coaxial cable to the feed point...!!!
  11. ,,,take this... sputnik1400.cst
  12. ,,,but this antenna does not have the 1200-1600 MHz band..!!! ,,,this is what the antenna you want should look like...!!!
  13. ,,,for this frequency range it still seems like a big antenna to me...!!!!
  14. ,,,for which frequency band do you want the antenna to be...???
  15. Here it... stella5.stl
  16. Andrew77... I don't know if this can help you....!!! double helix.stl

  19. The original design of the balun device, protected by patent, contains a bandpass filter, which is well agree on the antenna cable in the operating frequency range, reduces noise at its output and provides reliable lightning protection TV. This design of antenna is designed for reception of television decimeter waves (UHF) frequency range 470-862 MHz, allows us to keep the analog (21-69к)and digital (DVB-T/T2) signals. The antenna is passive and does not have a built-in amplifier in this regard does not require electric power 220 volts. If you need to increase the level of the received signal external power amplifier can be installed separately. ELECTRICAL PARAMETERS Frequency range, MHz 470-790 The wave resistance, Ohm 75 The gain (KU), dB 9,5-11 Beamwidth The level –3dB, deg In the horizontal plane 80-60 deg In the vertical plane 55-40 deg The coefficient of protective action, dB, more 20 The standing wave ratio (VSWR), <1,5 Maximum power, Втv 100 Polarization horizontal Connector type F DESIGN PARAMETERS Overall dimensions, mm 520х340х140 The material of the emitters-anodizing aluminium The material of the protective screen - hot galvanized steel Material mounting brackets -hot galvanized steel Weight of antenna with mounting bracket, g 340 The diameter of the prop, hold the mounting bracket, mm 15-55 The maximum wind speed, km/h 160
  20. ,,,a MiMo construction variant with rectangular patches...
  21. Sealed box for 3G / 4G modem with built-in wide-band MIMO antenna and integrated 10-meter USB cable. The device is completely ready for self-installation: inside the case you will find two CRC9 pigtails for connecting the antenna part to the modem, and the complete mount will allow you to easily install the PETRA-12 MIMO 2x2 BOX on a facade bracket, pole or remote mast. Nothing prevents the device from being used indoors as well! Communication standardsGSM-1800, UMTS-2100, LTE1800, LTE2600 Frequency range 1700-2700 MHz Gain factor 10-13 dBi Bottom width in the H-plane 30–48° Bottom width in the E-plane 46–63° Input impedance 50 ohms SWR in the operating frequency range≤ 1,6 Polarisation vertical + horizontal Permissible power 10 W Forward / backward ratio 14-15 dB Side lobe level≤ -10 dB Decoupling between ports in the operating range≥ 32 d RF connectors 2 x CRC9 USB Cable Length 10 m Antenna Material FR-4, galvanized steel Material of the protective box polycarbonate+ABS Mounting material galvanized steel Shell Protection IP54 Permissible wind speed 25 m / sec Operating temperature range-40°C to +80°C Size 260 x 135 x 90 mm Weight 1 kg Equipment PETRA-12 MIMO BOX antenna with CRC9 connectors, 10 m USB extension cable, pipe or mast mounting kit, user manual
  22. I would also need other sizes for this...
  23. Universal antenna Petra-9 MIMO 2x2 built-in professional sealed box. CRC9 connectors. F=1700-2700 MHz. GAIN=9dBi. Polarization X-pol. Standards: LTE-A, LTE1800, LTE2600, UMTS2100, WIFI. PETRA-9 MIMO 2x2 Box is the antenna combined with a large sealed box in which you can put any 3G/4G modem and even router. The antenna is provided with connectors - CRC-9. The connection of modem to PC or router located in the room is via a USB extension cable. A sealed box will protect the modem from adverse weather conditions!
  24. ,,,one port is horizontally polarized and the other is vertically polarized...!!!
  25. That's how it should be...
