“…Compared with the diodes at 5.8 GHz [6,11] or other higher frequencies [2], the diodes at 2.45 GHz [12] provide higher breakdown voltage and power capacitance. A 2.45 GHz rectenna array presents better DC voltage and power handling for practical applications.…”

Abstract-The microwave power transmission is an approach for wireless power transmission. As an important component of a microwave wireless power transmission systems, microwave rectennas are widely studied. A rectenna based on a microstrip dipole antenna and a microwave rectifier with high conversion efficiency were designed at 2.45 GHz. The dipole antenna achieved a gain of 5.2 dBi, a return loss greater than 10 dB, and a bandwidth of 20%. The microwave to DC (MW-DC) conversion efficiency of the rectifier was measured as 83% with 20 dBm input power and 600 Ω load. There are 72 rectennas to form an array with an area of 50 cm by 50 cm. The measured results show that the arrangement of the rectenna connection is an effective way to improve the total conversion efficiency, when the microwave power distribution is not uniform on rectenna array. The experimental results show that the highest microwave power transmission efficiency reaches 67.6%.

“…A lot of researches are interested in a single rectenna or a low power rectenna array at a fixed transmission distance [2][3][4][5][6][7][8][9][10][11]. In an MPT system, a rectenna array at a level of several watts is convenient and useful [9].…”

“…The rectifier consisted of an HSMS-2862 microwave Si Schottky detector diode pair (R s = 6.0 Ω, C j0 = 0.18 pF, V bi = 0.65 V, and V B = 7 V for each diode), a capacitor C and a load resistor R L . The equivalent circuit parameters are given in [15]. The diode pair was connected as a voltage-doubler to increase the output DC voltage (V D ).…”

“…Wireless power transmission in the 5-6 GHz band has been studied before in [15][16][17][18][19][20][21][22][23][24] primarily because of the band being unlicensed and that it allows larger antenna effective apertures resulting in higher antenna gain. Earlier wireless power transmission (at 5.7 GHz) to a buried sensor antenna in concrete was demonstrated in [22].…”

Abstract-A reconfigurable stacked patch antenna is introduced for wireless power reception and data telemetry application in sensors. The proposed antenna operates at 5.8 GHz with 9.4 dBi gain and 7.6% bandwidth. At a lower frequency 2.45 GHz the antenna operates as a planar inverted-F antenna (PIFA) with 3.3 dBi gain and 2.0% bandwidth. Switching between the two regimes of operation is achieved using PIN diodes. It is proposed that the antenna can be used for wireless power reception in sensors at 5.8 GHz and for data telemetry in between a sensor and a control station at 2.45 GHz. The wireless power reception ability of this antenna was tested and verified by developing a high efficiency schottky diode rectifying circuit. The RFto-DC conversion efficiency was 85% for an input power density level of 1 mW/cm 2 .

Abstract-This paper reports a 2.45 GHz, low power dual circularly polarized (DCP) and dual access rectenna. It contains two dc-recombined rectifiers and a cross-slot coupled square patch antenna fed by a microstrip line. A judicious dc recombination scheme allows to minimize the RF power imbalance between accesses caused by multipath effects and consequently arbitrary polarized incident waves. The proposed rectenna is then able to harvest linearly polarized, right-hand circularly polarized (RHCP) and left-hand circularly polarized (LHCP) electromagnetic waves, with nearly stable performances. The rectenna has been optimized at −15 dBm per access and dedicated to remote and contactless supply low consumption sensors. It has been experimentally tested with very low power densities from 0.057 µW/cm 2 (E rms = 0.46 V/m) to 2.3 µW/cm 2 (E rms = 2.95 V/m). At 1.49 µW/cm 2 (−15 dBm on each rectifier), the structure exhibits an output dc voltage and a global efficiency of 189 mV and 37.7%, respectively when the azimuthal angle (Φ) of the incident field is equal to 0 • . Due to the nearly constant total gain of the DCP antenna and an appropriate dc recombination of the two rectifiers, the global efficiency slightly varies between 37.7% and 41.4% when the azimuthal angle (Φ) varies between −90 and 90 • .
