10 ghz waveguide slot antenna

Abstract: This paper introduces a linear slot antenna array based on an empty substrate integrated waveguide at 28 GHz. The proposed antenna offers the advantages of reduced weight and fabrication cost as well as facilitates relatively easier integration with planar electronic components as compared to conventional slotted waveguide antenna arrays. Design of Slotted Waveguide Array Antenna Fed by H-Plane ... resonant slot length in our antenna is half of the free space wavelength whereas slot width is one twentieth of free space wavelength. Excitation port is placed at the end opposite to the shorter end of waveguide. The details of the design parameter of the waveguide, slot dimensions and their positions are summarized in TABLE 1.

The measured results show that the antenna has a wide impedance matching bandwidth of 28.6% from 30 to 40 GHz for |S11| ≤10 dB and a wide axial ratio (AR) bandwidth of 22.8% from 31.5 to 39.6 GHz for AR ≤ 3 dB.

Abstract: A multi-beam slot array antenna is proposed in the 10-GHz band for a monopulse tracking system with resolution enhancement techniques. The antenna architecture combines a four-subarray substrate integrated waveguide (SIW) slot antenna, a multi-beam-forming network of microstrip Rotman lens array, and a SIW comparator of four-quadrant monopulse technique.

W1GHZ 10GHz Page - Antennas Dick, K2RIW, has been talking about periscope antennas for so long that I had to put one up and show him how to do it! The periscope antenna worked great for rainscatter during the June VHF Contest. I worked four grids on 10 GHz, best DX >130 miles, during heavy rain. OZ2OE Technical Home Page - 10 GHz waveguide slot antenna. Design of a 10 GHz beacon antenna. A standard WG16 waveguide is used. Principle: A slotted waveguide antenna works by radiating energy from the inside though a number of slots cut in the waveguide. Each slot acts as a (slotted) dipole, with the polarity opposite the direction of the slot. A vertical slot gives a horizontal polarisation.
