WebThe two main considerations of this beam width are Half Power Beam Width (HPBW) and First Null Beam Width (FNBW). First Null Beam Width According to the standard definition, “The angular span between the first pattern nulls adjacent to the main lobe, is called as the First Null Beam Width.” WebAntenna Theory End fire Array - The physical arrangement of end-fire array is same as that of the broad side array. The magnitude of currents in each element is same, but there is a phase difference between these currents. This induction of energy differs in each element, which can be understood by the following diagram. WebJun 5, 2024 · The transmitter of the antenna converts an electrical signal into electromagnetic signal form and this EM signal propagates in a medium like air or vacuum to the receiver end of the antenna, where at the receiver end the antenna converts the EM wave back to an electrical signal. under the counter storage shelves
