Abstract
A method includes displaying a reference polar coordinate system on a display screen, and displaying a radiation pattern image on the display screen in juxtaposition with the displayed reference polar coordinate system. In another aspect, an angled line is drawn on a display screen to represent the proposed layout of a leaky coaxial cable. A point of interest is selected that is spaced from the proposed cable layout, and one of the segments of the cable is determined as likely to produce a dominant level of irradiation with respect to the point of interest.
Claims19
A method comprising:
- displaying a first polar coordinate system on a display screen;
- displaying a first radiation pattern image on the display screen, the first radiation pattern image including a second polar coordinate system and a first pattern region indicative of a radiation pattern generated by an antenna in a horizontal plane;
- scaling and moving said first radiation pattern image to bring the second polar coordinate system into coincidence with the first polar coordinate system;
- defining a scale for the first polar coordinate system to reflect a parameter of the first radiation pattern image;
- marking points on a boundary of the first pattern region;
- deriving horizontal pattern data from said marked points;
- displaying a second radiation pattern image on the display screen together with the first polar coordinate system at a time when the first radiation pattern image is not displayed on the display screen, the second radiation pattern image including a third polar coordinate system and a second pattern region indicative of a radiation pattern generated by the antenna in a vertical plane;
- scaling and moving the second radiation pattern image to bring the third polar coordinate system into coincidence with the first polar coordinate system;
- defining a scale for the first polar coordinate system to reflect a parameter of the second radiation pattern image;
- marking points on a boundary of the second pattern region;
- deriving vertical pattern data from said points marked on the boundary of the second pattern region;
- and
- generating three-dimensional pattern data from said horizontal and vertical pattern data.
