Antenna Array Response & Beamforming
Educational tool for 5G Wireless Communication concepts
1. Array Geometry
End-fire (0°)
Broadside (90°)
End-fire (180°)
Theoretical Concept
As per Figure 2, the extra path distance to reach the next element is \(d \cos\theta\). For \(d = \lambda/2\), the phase shift \(\psi\) between elements is:
\[ \psi = \pi \cos(\theta) \]
The array response vector \(a(\theta)\) becomes:
[1, e^{j\psi}, e^{j2\psi}, ...]

3. Resulting Beam Pattern
The main lobe "points" to \(\theta\) by constructive interference.
