Youn nan fonksyon debaz yo nan antèn lan transmèt se jwenn enèji ki soti nan feeder la emiz soti nan espas nan vwazinaj la, fonksyon debaz yo nan de a se pi fò nan enèji nan emi nan direksyon a vle. Vètikal yo mete mwatye onn dipol gen yon plat nan "beye a" ki gen fòm ki genyen twa dimansyon modèl (Figi 1.3.1a). Malgre ke ki genyen twa dimansyon modèl stereoskopik, men difisil trase Figi 1.3.1b ak Figi 1.3.1c montre de li yo modèl direktè lekòl avyon, grafik pentire antèn la nan yon direksyon ki nan yon direksyon avyon espesifye. Figi 1.3.1b ka wè nan yon direksyon ki aksyo nan radyasyon an zewo Capteur, direksyon an radyasyon maksimòm nan plan an orizontal; 1.3.1c ka wè nan figi a, nan tout direksyon nan plan an orizontal ki gwo tankou radyasyon an.

One of the basic functions of the transmitting antenna is to get the energy from the feeder radiated out to the surrounding space, the basic functions of the two is to most of the energy radiated in the desired direction. Vertically placed half-wave dipole has a flat of the "donut"-shaped three-dimensional pattern (Figure 1.3.1a). Although three-dimensional stereoscopic pattern, but difficult to draw Figure 1.3.1b and Figure 1.3.1c shows its two principal plane pattern, graphic depicts the antenna in the direction of a specified plane direction. Figure 1.3.1b can be seen in the axial direction of the transducer zero radiation, the maximum radiation direction in the horizontal plane; 1.3.1c can be seen from the figure, in all directions in the horizontal plane as large as the radiation.
