“…Since the surface roughness was very similar for all waveguides under test, again the conductivity was the main contributor to the difference in losses. Results reported in [8] show that the waveguide with conductive paint had the highest loss.…”

This paper discusses the transmit properties of 3D printed horn antennas with different metallization processes: vacuum metallization, electroplating, and conductive paint. Electroplating was done with three metal thicknesses: 3m, 6m, and 50m. Microwave signals of up to 100W at frequencies of 7.5GHz, 12.5GHz, and 18GHz were applied to the antennas. Measurements show that the metallization process has to be taken into consideration for high power applications. The antenna with conductive paint was not able to handle high power signals, while the other four had similar performance as a regular horn antenna.

“…Recently, various antennas for UAV applications have been reported, including horn antennas, conductive spray‐coated three‐dimensional‐printed antennas, and patch antennas. For UAV applications, antennas should be aerodynamically designed and easily installable on the aircraft fuselage to avoid potential performance deterioration.…”

We propose a low‐profile tilted‐beam waveguide slot antenna using corrugations for unmanned aerial vehicle (UAV) applications. The proposed antenna consists of a WR‐90 rectangular waveguide with a central slot on top and two asymmetric corrugations. The antenna satisfies a 10‐dB return loss from 9.82 to 10.18 GHz. To realize the low‐profile characteristic, the proposed antenna is fed from the flank instead of the bottom of the waveguide. In addition, the proposed antenna attains a tilted beam pointing 45 degrees from the broadside direction due to the asymmetric corrugations on the conducting plate. The antenna has a measured peak gain of 6.95 dBi at the center frequency of the operation band, which satisfies the gain requirement for UAV applications. The experimental and simulated results of the proposed antenna are in good agreement.

“…In contrast to metal detecting, GPR can be used for detection of low-metal content or non-metal content targets. Subsurface radar suffers from two typical problems, a strong clutter response from the surface and high signal-to-clutter power levels in the underground [3], [4]. This paper investigates clutter reduction by experimental study of two polarimetric decomposition techniques; the model based technique of Yamaguchi [5] and Pauli [6] polarisation parameter analysis.…”

The effect of different decomposition techniques on the imaging and detection accuracy for polarimetric surface penetrating radar data is studied. We derive the general expressions for coherent polarimetric decomposition using the model based polarimetric decomposition of Yamaguchi technique and compare these with some Stokes and Pauli coherent polarisation decomposition parameters. These mathematical treatments are then applied to laboratory based X-band (8.2-12.4GHz) full polarimetry near-field radar measurements taken of shallow buried reference and calibration objects and different landmine types. The Yamaguchi polarimetry filters demonstated significant surface and sub-surface clutter reduction and contrast in subsurface imagery, with some loss in signal power. The Stokes and Pauli parameters demonstrated similar clutter reduction in subsurface imagery providing additional beneficial information on the targets scattering mechanism. Combining these techniques contributes to an improvement of subsurface radar discrimination and understanding of the target type.
