“…A broadband triangular omnidirectional antenna was introduced in [9] for RFEH over the broadband bandwidth. In [10,11], a dual-band monopole antenna, broadband slot antenna, and flexible substrate antenna in [12] are introduced for RFEH applications. As we know, rectenna is a combination of the antenna with rectifier or voltage doubler, impedance matching network, and nonlinear diodes (high-frequency diode).…”

This article discusses the design analysis of a wideband rectenna (Antenna + Rectifier). It empowers low power devices, battery-less power sensors, and many Internet of Things (IoT) devices. The main focus of this work is divided into two parts. First, to develop the power to operate the wideband frequency of operation without system complexity. To obtain rectifier bandwidth sufficiently, L-section impedance matching with dual Schottky diode HSMS270B is proposed. Second, to improve the rectenna efficiency and output DC power. Wideband rectenna harvests the maximum RF power of 30.590 dBm, 1145.51 mW, 10.703 Volts at 3.2 GHz. The harvested power is easily available to power up the low powered sensor such as gas sensor (500-800 mW), pressure sensor (10-15 mW), and temperature sensor (0.5-5 mW). The peak conversion efficiency of the rectenna is 88.58% at 0 dBm, 34.70% at 10 dBm, and 53.52% at 20 dBm under the load resistance of 100 kΩ. The proposed work shows a 20-25% improvement in conversion efficiency with this approach. For efficient RF energy harvesting applications, the proposed rectenna is capable of covering a wideband application from 1.975 to 4.744 GHz with a single radiation patch. This shows that the novel approach of the considered work and the proposed rectenna has the specialty to capture more energy from a wide area at once.

“…Dual-band antenna is one of the solutions of reducing the antenna numbers in a terminal. Many dual-band mobile terminal antenna structures have been reported, including hook-shaped strip structure [1], an open-loop ring resonator feeding element and a T-shaped radiating element [2], and substrate-integrated suspended line structure [3].…”

A coplanar waveguide- (CPW-) fed dual-band multiple-input multiple-output (MIMO) antenna for 2.45/5.5 GHz wireless local area network (WLAN) applications is presented in this paper. The presented MIMO antenna consists of two identical trapezoidal radiating elements which are perpendicular to each other. The size of the entire MIMO antenna is 50 × 50 × 1.59 mm3, which is printed on a FR4 substrate. The measured impedance bandwidth of the proposed antenna is 2.25–3.15 GHz and 4.89–5.95 GHz, which can cover IEEE 802.11 a/b/g frequency bands. A rectangular microstrip stub is introduced to achieve a good isolation which is less than −15 dB in both operation frequency bands. The measured peak gain is 5.59 dBi at 2.45 GHz and 5.63 dBi at 5.5 GHz. The measured antenna efficiency is 77.8% and 80.4% in the lower and higher frequency bands, respectively. The ECC values at the lower and higher frequencies are lower than 0.003 and 0.01, respectively.

“…Wireless local area network (WLAN), covering a low band from 2.4 to 2.485 GHz and a high band from 5.1 to 5.875 GHz, is significant in many communication applications. Antennas are the key components as the devices of transmitter and receiver in the usage scenarios of WLAN are facing many challenges, such as low profile, miniaturization, multi‐band, and easy manufacture 1‐3 . Many designs employed the stereo structures for horizontal omnidirectional function, which are easy to have a broadband characteristic 4,5 .…”

In this letter, a compact omnidirectional dual‐band antenna is designed for wireless local area network applications. The proposed antenna is printed on the two sides of an FR4 substrate that the total dimension is 12 × 46 × 0.5 mm3. A dipole antenna is used to cover the lower operating band (2.45 GHz), while a capacitances‐loaded patch generates a higher resonance (5.5 GHz). This antenna has a good impedance matching in the operation band, and the gain is 2.28 and 4.42 dBi in the lower and upper bands, respectively. To address the problem that the performance will drastically decline when the antenna is located on a ground, a quarter wavelength spiral line is employed to decrease the negative effect of the ground. Two proposed dipole antennas, placed on a horizontal ground as a MIMO antenna system, are analyzed with different configurations. The results reveal that the proposed method can effectively reduce the ground plane effect and improve the diversity performance, which has huge potential applications in MIMO system.
