Cheng* Fundamental Science on Extreme High Frequency Laboratory, School of Electronic Engineering, University of Electronic Science and Technology of China, Chengdu 611731, China Abstract|A new technique for designing the substrate integrated Design of Microstrip Transition to Substrate Integrated Waveguide... Abstract. Substrate integrated waveguide is a good candidate for implementing millimeter wave applications. This paper presents microstrip transition to substrate integrated waveguide fed slot antenna for 60 GHz applications, which is developed by Rogers RT/Duroid 5880 with a dielectric constant of 2.2, substrate height of 0.381 mm and metallization thickness is 0.025 mm. Dielectric waveguide slot antenna with integrated filter for... Because the antenna is based on rectangular waveguide structure, it can be easily integrated with a high-Q filter. The prototype of the integrated antenna and filter with area of 50times30 mm 2 exhibits half-power beamwidth of 54.7deg in the horizontal and 16.2deg in the vertical, respectively, as well as the sharp bandpass characteristics of ...
How a Slotted Waveguide Antenna Works This antenna, called A slotted waveguide, is a very low loss transmission line. It allows to propagate signals to a number of smaller antennas (slots). The signal is coupled into the waveguide with a simple coaxial probe, and as it travels along the guide it traverses the slots.
Slotted waveguide - Wikipedia A slotted waveguide has no reflector but emits directly through the slots. The spacing of the slots is critical and is a multiple of the wavelength used for transmission and reception. The effect of this geometry is to form a high gain antenna that is highly directional in the plane of the antenna. SIW Based Slot Antenna In X-Band Using Rogers/RT duroid 5880 ...

SIW is a transition between microstrip and dielectric-filled waveguide (DFW). Dielectric filled waveguide is converted to substrate integrated waveguide (SIW) by the help of vias for the side walls of the waveguide. Figure 1: (a) Air filled waveguide, (b) dielectric filled waveguide, (c) substrate integrated waveguide

Abstract: In this paper, we demonstrate a waveguide slot array antenna by integration of T-shaped filters using the diffusion bonding of laminated thin metal plates. The excellent performance of the T-shaped filter has been experimentally verified by the in-band transmission and the out-of-band rejection of the fabricated antenna.
