Figure 4. Slotted waveguide antenna fed by a coaxial feed. The resulting S-parameter graph is shown in the following figure. Note that the antenna has a very large drop in S11 around 10 GHz. This indicates that most of the power is radiated away at this frequency. The bandwidth of the antenna (if defined as where S11 is less than -6 dB) extends ... waveguide slot Antenna for 2 4GHz - YouTube My first attempt at building the waveguide slot hopefully the first of many as I have a few ideas how I can adapt this basic design. ... 12 Slot Waveguide Antenna for 2.4GHz ... 2 4 ghz waveguide ... 10GHz waveguide slot antenna - DL6NCI 10GHz WAVEGUIDE SLOT ANTENNA. Calculation program from DK3BA,DH6SBN (version 5.40 in german) DOWNLOAD 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.
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. This work ...
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. Integrated waveguide slot antennas | Request PDF Waveguide slot antennas integrated on microwave laminate are presented, and single and dual slot antennas are described, which operate at 10 GHz. below 6cm slot antenna 20 slots 14.7 dbi 125 euro ... - PE1RKI 10ghz slot antennas are 125 euro, i used to sell them for 150 euro but i noticed i had competition in this area so i lowered price. 10ghz and 24ghz can have waveguide or sma input. Many of my antennas are now on repeaters and beacons in many europe countries. below 6cm slot antenna 20 slots 14.7 dbi 125 euro a piece. closeup
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.
