Antenna Radiation Patterns

Radiation patterns of a planar antenna array composed of 7x7 half-wave dipole elements are presented in both polar and Cartesian coordinate systems. These radiation patterns are highly beneficial for understanding the directional characteristics of antennas. Radiation patterns visually represent the radiation intensity distribution across different directions, helping engineers analyze the antenna's radiation behavior and spatial coverage. By examining these patterns, key parameters such as main lobe direction, beamwidth, and radiation gain can be determined. The implementation typically involves calculating the array factor through phase manipulation and combining it with individual element patterns, often utilizing electromagnetic simulation tools or programming languages like MATLAB with specialized antenna functions. Therefore, studying and comprehending antenna radiation patterns holds significant importance for antenna design optimization and practical applications in wireless communication systems.
