Antenna Theory #12 | N-Element Linear Array | Beam Width, Side Lobes & Grating Lobes

Instructor: Dr. Süleyman Burak ÇELİK

This lesson extends the two-element array to an N-element uniform linear array and explores how increasing the number of elements shapes the radiation pattern. We derive the closed-form array factor for N equally spaced, equally excited elements and use it to examine beam width, side lobe levels, and the appearance of grating lobes.
