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.

A novel near-field microwave imaging system was designed and fabricated using the three-dimensional (3D) printing technique to manufacture X-band Pyramidal horn antennas and planar graded-index (GRIN) lenses. The flat lens focusing profile is synthesised by varying the refractive index radially in incremental steps that adjust the air-dielectric mixture. The lens is designed for direct attachment to the antenna aperture and transforms spherical waves emanating from antenna phase center into plane radiating waves. Simulated and measurement results show the antenna lens system input impedance is ≤ -10 dB, radiation pattern gain is between 17-20dBi over the 8.2-12.4GHz frequency band and when arrayed for polarimetry sensing has a polarisation cross-talk of ≤-50 dB. A ground penetrating radar system using the nearfield array was scanned over buried targets. The SAR results demonstrated high resolution and polarisation discrimination imagery capable of detecting subsurface objects.

Moreover, Adjusting upper passband is the most noticeable positive point. Considering these features, the proposed filter can be employed in wireless LAN applications.
