Abstract. A highly compact slot array antenna using substrate integrated folded waveguides (SIFW) is proposed in this\ud paper. The device has three key components: a non radiating SMA to standard waveguide transition, a power\ud divider from standard waveguide to folded waveguides, and slot arrays on the folded waveguide. Slot array antenna and plasma processing apparatus - US ... A slot array antenna, comprising: a power-feeding waveguide for feeding microwave power; and a plurality of rectangular radiating waveguides connected to a plurality of windows which are disposed along the longitudinal direction of the power feeding waveguide, so as to guide the microwave power from the plurality of windows to the outside of the antenna.

Busuioc, and S. Safavi-Naeini. Full Article PDF (511 KB) Abstract: A novel slot array antenna with two layers of substrate integrated waveguides (SIW) is presented for millimeter-wave wireless applications. Radar Basics - Slot Antennas Slot Antenna. Slot radiators or slot antennas are antennas that are used in the frequency range from about 300 MHz to 25 GHz. They are often used in navigation radar usually as an array fed by a waveguide. But also older large phased array antennas used the principle because the slot radiators are a very inexpensive way for frequency scanning arrays. . Slot antennas are an about λ/2 elongated ...

Design of a Two-Element Antenna Array Using Substrate ... The design of a two-element antenna array using the substrate integrated waveguide (SIW) technique and operating at 10 GHz is presented. The proposed antenna array consists of two SIW phase shifter sections with two SIW slot antennas. Analysis of Broad-Wall Longitudinal Slot Arrays in Standard ... Few literatures are also available on slot array [2 - 5]. Bastani and Rashed-Mohassed analysed planar slotted-waveguide array antennas with longitudinal slots using Method of Moments [2]. Moment method analysis of a horizontally polarized omni directional slot array antenna was done by Sangstar and Wang [3 -4]. Design of Slotted Waveguide Array Antenna Fed by H-Plane ...
