WebbIf the headlight is properly aimed (yellow dot with red border) we can now see heights and angles determined by the ECE that determine the correct and safest pattern for a headlight beam. Notice the data points are intentionally lower than the windshield of the oncoming vehicle, except for one. An antenna radiation pattern is a 3D plot, and 2D sections can be obtained by dividing the 3D plot into horizontal and vertical planes. The resulting patterns are called horizontal patterns and vertical patterns, respectively. Some common antenna radiation patterns are: 1. Non-directional patterns or omni … Visa mer The capability to radiate and receive radiations is a key feature of an antenna.
