文摘：A Ka-Band Quad-Ridge Horn Antenna (QRHA) was fabricated using two fabrication methods. The first method used conventional subtractive manufacturing, where the QRHA was fabricated from a block of A6061 aluminum using a 5-axis Computer Numerical Control (CNC) machine. The second method used additive manufacturing where the QRHA was fabricated from an aluminum alloy powder using a Selective Laser Melting (SLM) printer. Both antennas were tested in a compact antenna range and the performance was compared over 18 to 40 GHz. The gain measurements showed the 3D printed QRHA had less than 0.6 dB lower gain than the machined QRHA over the 18 to 31 GHz frequency range and less than 1.2 dB lower gain when tested up to 40 GHz operation. Based on the results, the feasibility of using metal 3D printing to fabricate wideband horn antennas operating up to Ka-Band was shown.
