A hollow substrate integrated waveguide (HSIW) is proposed to realize low-loss millimetre-wave (mm-wave) transmission lines. A 38 GHz waveguide slot antenna integrated with a cavity bandpass ... Design of Slotted Waveguide Array Antenna Fed by H-Plane Power Divider Waveguide fed slot array antenna has emerged as a popular candidate in radar applications, remote sensing, navigation and many other high frequency communication applications [1]. Because of the integration of the feed system and radiating elements they are low loss, exhibiting high values of radiation efficiency. They radiate linear polarization with reduced cross-polarization. The basic radiation mechanism for such antennas is very simple: a hole appropriately cut in the wall of a ... A Novel Structure of Multilayer SIW Filter and Patch Antenna In [14] the filter and antenna was designed using a multilayer structure with coupling slot and coaxial feeding methods was used on the both elements for the integrated design. However, the structure increases the Dielectric waveguide slot antenna with integrated filter ... 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 50×30mm 2 exhibits half-power beamwidth of 54.7° in the horizontal and 16.2° in the vertical, respectively, as well as the sharp bandpass characteristics of 25 to ...
The slot antenna, consisting of a narrow slit in a ground plane, is a very versatile antenna. With modification, it is amenable to waveguide, coplanar waveguide (CPW), coaxial, slot line, or microstrip feeding schemes and has been used in all aspects of wireless and radar applications.

It is used in designing passive circuits such as resonators, couplers, filters, power dividers, circulators, and antennas… Applications of Substrate Integrated Waveguide (SIW This thesis is focused on some applications of the Substrate Integrated Waveguide (SIW) structure in microwave engineering. It is mainly divided into two parts, covering a dual-band high Q filter and a broadband high gain ring slot antenna, both of which are based on SIW resonators. Design of Substrate Integrated Waveguide Multi-band Slots Abstract—In this paper, the design of slots array antennas based on Substrate Integrated waveguide (SIW) has been analyzed and simulated. A waveguide slot antenna has a vertical row of slots along the length of a vertical waveguide, with the array of slots increasing the gain by flattening the vertical beam. Active Filters Using Modern Design and Optimization
holes or slots periodically connecting top and bottom ground plane with substrate in middle. As they are planar, they can be fabricated on PCBs and also integrated with other planar components like microstrips [5-6]. A Quarter mode substrate integrated waveguide (QMSIW) which is quarter part of a square waveguide is applied in this antenna.
