<p>In this paper, a new dual-band radio frequency (RF) rectifier was designed. The proposed design is a low-profile structure with dimensions of <br /> 5×5.5 mm<sup>2</sup> owing to the use of lumped elements rather than the conventional transmission lines which occupy large footprints. This property can be potentially exploited to use the proposed rectifier in high dense rectenna arrays to generate high output direct current (DC) voltages. Furthermore, the proposed design adopts the composite right/left-handed composite right left-handed (CRLH) technique to realize the dual-band structure at frequencies of 1.8 and 2.4 GHz. Afterward, the matching circuit was optimized to make sure that it offers good matching. The frequency response shows good matching at both bands which are about -22 and -25 dB respectively. Eventually, the simulated circuit has a conversion efficiency of 52% and output voltages of 0.5 V at -5 dBm for the two bands.</p>

The implementation and application of single-layer fully-planar extended-composite right-/left-handed transmission lines (E-CRLH TLs) in substrate-integrated waveguide (SIW) technology are presented. The multiband CRLH behavior of these artificial lines is explained by considering the lumped element equivalent circuit model. The potential of these lines for dual-band and quad-band applications is demonstrated by designing and fabricating a quad-band Y-junction power divider and two dual-band band-pass filters. The main relevant advantage of SIW-based E-CRLH TLs over other E-CRLH lines is fabrication simplicity, since only a single metal layer must be etched and lumped elements are avoided. The fabricated prototypes exhibit very reasonable performance. It is remarkable that for dual-band band-pass filters, standard Chebyshev responses can be obtained to a very good approximation.
