Detailed Description

Simulates the far-field pattern of a uniform circular array (UCA) of vertical dipoles.

This script places N vertical dipoles evenly along a circular ring in the XY-plane, computes the total radiated E-field pattern in 3D (spherical coordinates), and compares the result with MATLAB’s Phased Array Toolbox implementation of a UCA.

Key features:

• Constructs a ring of SimpleDipole objects with specified radius and spacing
• Evaluates combined E-field (Etheta, Ephi) on a theta-phi grid
• Plots 3D radiation pattern in decibels using a custom plotting method
• Verifies result using phased.UCA and plots reference pattern for comparison

Parameters

• Frequency: 500 MHz
• Number of dipoles: 11
• Radius of ring: 1.5 m
• Dipole length: 0.5λ₀

Note

Dipoles are oriented vertically (along the Z-axis)

The total field is computed via direct summation of individual dipole fields
