Patent ID: 7583855

Claim:
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.
