摘要: Due to the low atmospheric absorption over W-band, numerous applications are expected, which should be developed at cost. Short wavelength makes dimension of antennas in this frequency range small, usually requires sophisticated and expensive fabrication process. This communication presents a class integrated wideband pyramidal horn can made low-cost multilayered printed circuit board (PCB) The proposed antenna radiates along broadside substrate uses waveguide (SIW) as its feeder. Transverse slot on top metallic surface end SIW is deployed drive antenna. Metalized via holes used synthesize walls. opening discretely flared from bottom layer. Measured bandwidth 35 GHz (70-105 GHz) while relatively constant gain 10 ± 1 dB obtained most bandwidth.
