Gaussian Beam Polyrod Antenna Systems

PublishTime：2021-04-28

To characterize dielectric materials, non-destructively, over a wide range of frequen-cies and applications, it is essential to direct the energy transmitted to the test sam-ple accurately. MWI Laboratories offers a range of Gaussian Beam Polyrod antenna systems that produce a collimating beam (without a focal point) to inspect composite materials.
Similar to a laser, MWI’s collimating RF beam is very direc-tional, narrow and prevents over-illumination of the sample. This makes it very easy for the user to determine where the energy is located in performing non-destructive testing (NDT) for dielectric material characterization, uniformity and defect detection measurements over a wide range of frequencies.
The Polyrod antennas produce a planar wave within 1 inch of the tip making the systems more stable for calibration, and making it easier to produce dB & phase data for permittivity/permeability. The systems are light-weight and easy to operate without the need for an RF engineer. Mechanical and software noise reduction improvements increase dynamic range greater than 70dB while reducing signal scattering and sample wrap-a-round.
MWI offers a range of Gaussian Beam Polyrod antenna systems – Polyrod antennas and compatible holders, in different designs and with different bandwidths. There are six Polyrod antenna configurations with a frequency range of 7-50 GHz, each of which can be placed within close proximately of anoth-er to create a dual-polarity setup, and a broadband antenna, the PRA0716, with a frequency range of 0.7 – 16 GHz.
When connected to a Keysight vector/performance network analyzer such as the Field Fox, PXI, PNA-X the MWI antennas can measure small resistive loaded and small composite materials parts sheets greater than 3.0 sq.ins.
