“…Measurements of the reflection coefficient corresponding to the three possible configurations were performed by using the experimental setup illustrated in Fig. 8 and verified by means of a Time Domain Reflectometry approach [42][43][44][45][46][47][48]. Results obtained this way were in a perfect agreement; they are summarized in Fig.…”

Abstract-This paper presents a low-cost patternreconfigurable microstrip antenna. The proposed design strategy uses a slotted patch antenna on a bi-layer structure as basic element of a switched parasitic array. Reconfigurability is obtained by means of PIN diodes used to vary the resonance frequency of the parasitic patches. Experimental results referring to a prototype consisting of an array of three elements optimized for the Ultra High Frequency (UHF) band of Radio Frequency IDentification (RFID) systems are presented and discussed. It is demonstrated that the proposed antenna exhibits a main beam that can be reconfigured into three different directions.

“…As for the radiation properties, experimental measurements were performed by using a software-defined radio (SDR) platform [11,43,44]. In particular, the Universal Software Radio Peripheral (USRP) equipped with the XCVR2450 daughterboard [45] and a rubber antenna was used as a signal source.…”

Remote monitoring of the elderly in telehealth applications requires that the monitoring must not affect the elderly's regular habits. To ensure this requirement, the components (i.e., sensor and antenna) necessary to carry out such monitoring should blend in with the elderly's daily routine. To this end, an effective strategy relies on employing wearable antennas that can be fully integrated with clothes and that can be used for remotely transmitting/receiving the sensor data. Starting from these considerations, in this work, two different methods for wearable antenna fabrication are described in detail: the first resorts to the combined use of nonwoven conductive fabrics and of a cutting plotter for shaping the fabric, whereas the second considered fabrication method resorts to the embroidery of conductive threads. To demonstrate the suitability of the considered fabrication techniques and to highlight their pros and cons, numerical and experimental results related to different wearable antennas are also reported and commented on. Results demonstrate that the presented fabrication techniques and strategies are very flexible and can be used to obtain low-cost wearable antennas with performance tailored for the specific application at hand.

“…In our design, we keep the rectenna circuit symmetric, avoid discontinuities and fabricate the PCB using milling tools only. While CPW rectenna have been proposed previously [4,[6][7][8], these designs are optimized for high incident power levels and/or use a secondary energy source. In this work, we seek to fabricate a rectenna in CPW dedicated to operation at low power levels near 2.45 GHz and designed towards rectenna array implementation such as in [9].…”

“…Rectenna array solution are less demanding in terms of design methodology, but they require the realization of several rectenna with highly repeatable characteristics. In the literature, microstrip technology is frequently used to fabricate rectenna [3][4][5] where vias through the substrate are used to create a connection to the ground plane. This step is difficult to reproduce and increases the time required to build a rectenna array; the introduction of each via implying at least one drilling, through-hole plating and soldering step.…”

Abstract-This paper presents the design and fabrication of a coplanar waveguide (CPW) rectenna using a sequential modular approach. The rectenna is printed on high permittivity, low-loss board ARLON AD1000 ( r = 10.35 and tan δ = 0.0023 @ 10 GHz). The rectifier section is realized with a single reverse-biased schottky diode SMS-7630 in reverse topology for which a diode model is obtained at −20 dBm for frequencies F 0 = 2.45 GHz and 2F 0 = 4.9 GHz. The low-pass filter and the impedance matching are synthesized from passive CPW structures. Co-simulation technique is used to overcome CPW simulation limitations and to integrate the diode characteristics. The antenna consists of a circular slot loop antenna with stub matching such that its input impedance is close to 50 Ω. The goal of this work is to design a rectifier to simplify and speed up the fabrication process of a rectenna array. We reduced the number of processes to etch the rectifier on the board and minimized the number of lumped elements. At −20 dBm, simulation of the rectifier with an ideal impedance matching network shows rectification at 2.45 GHz with efficiency of 12.8%. The rectifier and rectenna show efficiency of approximately 10% at an operating frequency of 2.48 GHz.
