The slot antenna is studied. The basic principles of slot antennas are presented, along with design parameters. Slot Antennas.... consider a dipole similar to the one shown on the right in Figure 2. Suppose the length of the dipole is 14.4 centimeters and the width is 2 centimeters, and that the impedance at 1 GHz is 65+j15 Ohms. The fields. Calculating Port Size. Calculate Port Size. The box port can be calculated with a simple formula. Box volume in cubic feet X 16 (the amount of port area in square inches per cubic feet of box volume). For example, 3.4 cuft X 16 sqin= 54.5 square inches of port area. Try to stay within 10% of this number. The port length should be 16 inches deep..

4 inch port, 3.68545 cf, 30hz gets 7.284inches (+1 for the flares) is 8.284. It's easier to round down to an easier fraction so 8.25inches. So with those dimensions and a 4 inch aero port 8.25 inches long, you'll be tuned to 30.05hz. When you are a beginner designing boxes, its easiest to use whole or half numbers for dimensions.

If you specified more than one port for the Number of Ports value the Flare Length Port Required value will be for each port. * - For the 2" Precision Port cut the center tube 5 inches shorter than the Flare Length Port Required value. * - For all other Precision Ports cut the center tube 6 inches shorter than the Flare Length Port Required value. Put it in a 4 cubic foot box with a 12.5" wide x 3" tall x 55.5" long port (or a variation of this size) with 3/4" round overs/coves in all corners that could impede airflow. See my build here. I should also note I used total volume in creating my port rather than measuring down the middle due to its folded nature. Example has 6 slots on each side for at total of 12 slots. The slots have identical length and spacing along the waveguide. Note how the slot position alternates about the centerline of the guide. The far wall of the waveguide has an identical slot pattern, so that you can see through the slots. If the pattern on the far wall were reversed, the two.
