For uniform linear arrays, an approximation for HPBW 1,2 is given as Equation 3: Figure 2 plots ... pattern is a linear multiplication of the element factor and array factor, so in a dB scale, they ...

8 isotropic elements Uniform spacing of 0.5 wavelengths No beam steering (broadside pattern) Visualizes the array’s radiation pattern in 2D ...

Abstract: A new low-cost, pattern-switchable, metamaterial-inspired, dielectric resonator (DR) 1-D linear array for 2-D beam-steering is presented by using a hybrid digital coding method. By loading ...

Abstract: The beam pattern of ultrawide-band (UWB) impulse array in the near field is discussed in this paper. The basic principle of beamforming of linear array in the near field for UWB pulse is ...

First, in blue, the same 30° plot from Figure 11 in Part 1 is repeated. Next, the d/λ spacing is increased to 0.7 to show how the antenna pattern ... is called beam squint. Figure 5. Beam squint ...

In this first of six articles, learn some of the basics of phased-array antenna patterns, starting with the simpler example of a linear array ... Shown are plots of phase shift (ΔΦ) between elements ...

This case also shows a full 180° shift betweenelements provides a theoretical 90° shift in beam direction. In practice, with real element patterns ... plot the array factor for several array sizes.
