Phased Array Antenna Hexagonal and Rectangular Array Patterns

In this text, we explore two fundamental configurations of phased array antennas: hexagonal arrays and rectangular arrays. Our analysis primarily focuses on characterizing and comparing the radiation patterns of these array geometries. Additionally, we examine the radiation patterns of circular horn antennas. Through systematic pattern analysis, we gain insights into the performance characteristics and distinct advantages of different antenna configurations. This discussion provides valuable guidance for selecting appropriate antenna geometries based on specific application requirements.

From an implementation perspective, hexagonal arrays typically require more complex element positioning calculations compared to rectangular grids, while rectangular arrays benefit from simpler Cartesian coordinate systems for element placement. Pattern generation algorithms for these configurations involve calculating array factors with proper phase weighting and incorporating individual element patterns. Circular horn antennas, often used as reference elements, require specialized field integration methods for accurate pattern computation.
