New Dipole Antenna Review & How-To

I’m pleased to introduce a new version of the PCB Dipole Antenna, a significant upgrade from the previous version. This has a nice VSWR of almost 1.0 at both 868Mhz (at default 78mm length), and 915Mhz (trimmed at 73.5mm). It could be trimmed anywhere down to 2.4Ghz but it will be a best performer for the wideband LoRa and FSK radios in the sub Ghz ranges. Be sure to check out the dipole section in the RF-Best-Practices Guide for more theory on the dipole antenna.

  1. Hi Felix,
    antennas looks great, but how do you convert balanced signal (what dipol is) to unbalanced signal (SMA)? There have to be some losses.

    • Yes there will be some loss but you may use a balun if you want to minimize those losses. In practice this dipole will perform better than the unbalanced monopole.
