چکیده
Planar antenna reflectors are the modern design trend of both multibeam and frequency-scanning arrays. The planar implementation is typically performed using substrate-integrated waveguide (SIW) technology. A reflector’s profile can be different from canonical one (parabolic, elliptic, hyperbolic, etc.) because effect spatial dispersion reflection coefficient SIW-based surface. It should synthesized considering magnitude argument field reflected such a surface to maximize efficiency reflection. In this article, we present millimeter-wave (mm-wave) slot array with horn–reflector feeding. We analytically formulate optimization SIW dimensions while accounting for coefficient. minimize Finally, demonstrate that dual-slot radiating element, avoid effects scan blindness along normal direction. prototype has been built good agreement achieved between measured results predicted based on calculations. ±17° beam scanning within 16% operational frequency range, no

Design of Millimeter-wave Slotted-Waveguide Planar Antenna for Sub-array of Beam-scanning Antenna
Beam-scanning antennas are attractive for high-bit-rate data communication systems and high resolution sensing systems in millimeter-wave band. Waveguide antenna is one of the most attractive antennas for such millimeter-wave systems because of its low loss and high efficiency characteristics in high frequency band. Horizontally-beam-scanning antennas such as phased arrays and DBF (Digital Beam...

متن کاملan infinite planar array of rectangular microstrip patch antenna analysis
the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...

This paper presents a novel planar matching load for travelingwave-fed substrate integrated waveguide (SIW) slot arrays. The load consists of a planar grounded coplanar waveguide (GCPW) matching load and a planar GCPW to SIW transition which makes the GCPW matching load compatible with the SIW. In the GCPW matching load a high frequency resistor is used to dissipate the remaining power. A trave...
متن کاملUWB Antenna Array with Comb Taper Slot Antenna Elements
A uniformly spaced comb taper slot antenna array is proposed for directional ultra-wideband (UWB) applications. The UWB array consists of four identical comb taper slot antennas, a mutistage with four-way microstrip UWB power divider, and four identical coaxial cable lines. A maximum gain of 15.5dBi within the band is obtained when the element separation is properly selected. The uniform spacin...
