Radiation Pattern
3D Pattern
Three-dimensional radiation patterns illustrate the antenna's signal strength distribution in all directions for frequencies 2400MHz, 2450MHz, and 2500MHz. These plots show the main lobe and side lobes.
H-plane
Horizontal plane (H-plane) radiation patterns for 2400MHz, 2450MHz, and 2500MHz, displayed in polar coordinates, indicate the antenna's directivity in the horizontal plane.
E1-plane
Vertical plane (E1-plane) radiation patterns for 2400MHz, 2450MHz, and 2500MHz, displayed in polar coordinates, show the antenna's directivity in one vertical plane.
E2-plane
Vertical plane (E2-plane) radiation patterns for 2400MHz, 2450MHz, and 2500MHz, displayed in polar coordinates, show the antenna's directivity in another vertical plane.
Test Setup
The test setup diagram illustrates the connection of various equipment for antenna testing, including a computer, network analyzer, turntable controller, call box, and RF switching units, all integrated to measure antenna performance within a controlled environment.
A photograph shows the anechoic chamber used for testing, featuring the antenna mounted on a turntable, surrounded by RF-absorbent acoustic foam panels and lighting, with test equipment visible in the background.
