RF Explorer Near Field Antenna Kit

The RF Explorer Near Field Antenna Kit is a set of 4 high performance antennas designed for the most demanding RF diagnosis tasks:

  • RFEAH-25 – H-Loop magnetic 25mm diameter
  • RFEAH-15 – H-Loop magnetic 15mm diameter
  • RFEAH-5 – H-Loop magnetic 5mm diameter
  • RFEAE-10 – E-Field stub 10mm length

The low loss design of these antennas exhibits at least 10dB more sensitivity than other near field antennas in the market, at a much lower cost. Compared with other near field antennas, RF Explorer are smaller and lighter, exactly what fits best when space is constrained in a PCB.

AntennaKit description

Magnetic H-Loop

The three magnetic H-Loop antennas are very sensitive, compact and easy to use antennas for all sort of radiation sources.

RFEAN25 sniff1

Three different options: As the antenna diameter gets shorter, the spatial resolution increases at the cost of some sensitivity loss; you should select RFEAH-25 for best sensitivity with connectors, large ICs and isolated signal traces, whereas RFEAH-5 works best for very narrow selective work in a populated PCB with close-by signal traces. RFEAH-15 is a good in-between compromise.

H Loop 15 connector small

Stub E-Field

The electric field RFEAE-10 offers a remarkable spatial resolution to determine the exact component in the PCB causing a problem, no matter how small it is. You can easily determine signal level at the input and output of a filter, amplifier, mixer, etc.

Using the antennas

Included with the antenna is high quality semirigid RF cable; this cable works as the handler of the antenna. The big advantage of this approach: you can shape the cable the way you want for the antenna to be located exactly where you need it, in most cases with no need to hold it in your hand.

The RF cable is coupled with an easy to use SMA Push-On adapter; therefore the different antenna models can be easily plugged in/out as required for the task. There is no need to deal with SMA nuts, just plug-n-play antennas.

Characterized response

  • Characterized response for most used FR-4 PCB thickness included for each antenna: 10mil, 20mil, 32mil (0.8mm) and 64mil (1.6mm)
  • Coupling factor amplitude correction files available on RF Explorer for Windows automatic adjustment.
