“…At lower microwave frequencies, the equivalent circuit of the unbiased, or negatively biased, diode can be reduced to a "π" electrical network of capacitances, as depicted in Figure 4. The above "π" network accounts for the total capacitance CT, as well as the small-value parasitic capacitances to the ground (if considered), Cm1 and Cm2, where CT is the sum of the junction capacitance Cj and the parasitic capacitances Cpp, as shown in Equation (2). The above "π" network accounts for the total capacitance C T , as well as the small-value parasitic capacitances to the ground (if considered), C m1 and C m2 , where C T is the sum of the junction capacitance C j and the parasitic capacitances C pp , as shown in Equation (2).…”

This paper presents and discusses the careful modeling of a Zero Biased Diode, including low-frequency noise sources, providing a global model compatible with both wire bonding and flip-chip attachment techniques. The model is intended to cover from DC up to W-band behavior, and is based on DC, capacitance versus voltage, as well as scattering and power sweep harmonics measurements. Intensive use of 3D EM (ElectroMagnetic) simulation tools, such as HFSS TM , was done to support Zero Biased Diode parasitics modeling and microstrip board modeling. Measurements are compared with simulations and discussed. The models will provide useful support for detector designs in the W-band.

“…For power splitting architecture (or another single antenna architecture) with out-of-band approach, it is necessary to employ a suitable antenna with enough bandwidth to cover all adopted operating bands. The use of a broadband planar antenna is widely explored for communication proposes and, nowadays, it emerges for RF energy harvesting with promising results [12][13][14][15][16]. For this work, the chosen one is the QY that has wide bandwidth, moderate gain and good radiation pattern characteristics [17,18].…”

Aiming to improve the SWIPT (Simultaneous Wireless Information and Power Transfer) technologies, this work proposes a novel Dual‐Output quasi‐Yagi antenna (DOQY), designed by combining a single classic quasi‐Yagi antenna (QY) and a dedicated frequency splitter in order to behave as two distinct antennas, one operating at 1.8 GHz mobile communication band for data communication and another at 2.4 GHz ISM band for out‐of‐band energy harvesting. To validate the proposal, the results of the DOQY are compared to those presented by a reference quasi‐Yagi antenna (QYref) with the same dimensions. Additionally, for analysis of the energy harvesting capacity and the corresponding necessary RF design criteria, the antennas are connected to a well‐established rectifier system and its performances were compared. The novel architecture presents a antenna gain performance of 70%, in comparison with QYref in both central frequency bands, presenting, however, the same performance in energy harvesting. At 1.8 GHz the antenna gain performance is increased to 81% of the QYref, adding the rectifier circuit in their respective port. These satisfactory results endorse the operability of the DOQY for SWIPT application, adding a new port without compromising the system performance.

“…To solve the problem, broadband or multiband rectenna provides an alternative to capture RF energy from different channels and outperforms the single band rectenna. In the design of the broadband rectenna, the antenna is usually fed by a strip of microstrip line to broaden the bandwidth [13][14][15]. Antenna array is another alternative for the expansion of bandwidth through the combination of antenna elements [16,17].…”

“…Slot rectenna is a solution for a compact design with the variation of the surface current length as reported in [29][30][31]. Besides, fractal rectenna, by introducing fractal theory into the design of the antenna, provides another approach for miniaturisation due to the characteristic of self-similarity [10,15,22,32,33].…”

A novel compact dual‐band rectenna is presented for efficient radio frequency (RF) energy harvest at 2.45 GHz WiFi and 3.5 GHz WiMAX bands. The proposed rectenna is composed of an optimised tree‐like receiving antenna and a compact rectifier based on a two‐branch matching network. The tree‐like antenna is found to feature a dual‐band characteristic, high radiation efficiency, and improved reflection coefficient with the newly designed slotted ground plane. By introducing the matching network which consists of two different radial branches, the proposed antenna is well matched with the rectifying circuit and most part of the received power could be delivered. Besides, in order to eliminate the coupling effects, reduce the energy loss and minimise the overall dimension of the rectenna, three narrow stubs on the ground plane of the antenna are designed to perform as the ground of the rectifier. The results have demonstrated the designed rectenna exhibits relatively stable conversion efficiency for the load value varying from 0.9 to 20 kΩ under low input power and the maximum conversion efficiency is observed to be 60% at 2.45 GHz and 53% at 3.5 GHz under the input power of 0 dBm.
