Abstract
This paper proposes a method for the generation of a Bessel beam. The beam is generated with the use of a graded refractive index (GRIN) lens and multiple-feed-per-beam (MFPB) technique. The lens is illuminated by a 2×2 antenna array where all radiating elements are placed off-axis, so each element produces beams tilted from the broadside direction. The combined radiation patterns, generated by individual radiating elements, result in creation of the Bessel beam. The concept has been experimentally verified with a biodegradable polyactic acid (PLA)-based GRIN lens antenna operating at 12 GHz. The lens antenna achieves a maximum realized gain of 17.2 dBi at 12 GHz, which corresponds to the improvement in gain of 8.3 dB over the 2×2 array. The maximum gain improvement in the non- diffractive region is 10.3 dB.
