Implementation and Experimental Verification of a Smart Antenna System Operating at 60 GHz Band

Beam-Deflection Using Gradient Refractive-Index Media for 60-GHz End-Fire Antenna

“…In [12] it is shown that a 2D array of resonators with subwavelength separation results in phase discontinuities in the propagating EM wave as it traverses the interface between two media as predicted by the generalized Snell's law: (1) Where  i and  t are angle of incident and refraction, respectively, and is the gradient of phase discontinuity. This principle is employed here to steer the EM radiation emanating from a printed dipole antenna.…”

“…This is attributed to the phase discontinuity in the GRIM region according to the generalized Snell's law in Eqn. (1), where the effective path length of each ray traversing in GRIM region is different than for identical unit-cell loading. …”

RF microsystems for wireless sensors networks

“…The investigation of new frequency bands [1] and new geometries [2] will make possible to have smaller antennas to integrate in wireless microsystems [3,4]. This makes the chose of the most suitable frequency, one of the more decisive aspects in the design of RF transceivers.…”

Array Elements

“…A TEM horn antenna on LTCC with an air cavity was used by Kim et al (2006). A switchable antenna system uses pyramidal waveguide horns to allow optimization of system S/N (Celik et al, 2008). A monopulse slot array was developed by Liu et al (2009).…”
