“…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]. However, if the power splitter is a frequency-independent device, there will be losses of useful power in the system.…”

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.

“…The antenna used in an IR-UWB radar system must have a wide bandwidth to transmit and receive the impulse signals of nano-second units in a specific direction, as well as high gain and directional radiation patterns to track the location of an object. Conventional IR-UWB antennas have been studied for various uses, such as in Vivaldi antennas [2,3], patch antennas [4], Yagi-type antennas [5,6], and tapered-slot antennas (TSA) [7,8]. These antennas have difficulty tracking objects that are located over a wide area owing to the relatively narrow beamwidth.…”

The single antenna used in conventional ultra-wideband radar has difficulty tracking targets over a wide range because of a relatively narrow beamwidth. Herein, we propose a beamforming antenna that can track targets over a wide range by electronically controlling the main beam of the antenna. The proposed beamforming antenna was fabricated by connecting a 1 × 4 linear array antenna and a 4 × 4 Butler matrix. The Butler matrix was fabricated in a laminated substrate using two TRF-45 substrates. Furthermore, the input Ports 1–4 generate a phase difference at regular intervals in each output port, and the output phase is fed to the array antenna. The proposed tapered-slot antenna was fabricated on a Taconic TLY substrate, and the impedance bandwidth of the antenna was achieved within a wide bandwidth of 4.32 GHz by satisfying a VSWR (Voltage Standing Wave Ratio) ≤2 within the 1.45–5.78 GHz band. Furthermore, the fabricated antenna has directional radiation patterns, which was found to be a suitable characsteristic for location tracking in a certain direction. Finally, the beamforming antenna has four beamforming angles, and to verify the performance for an indoor location tracking application of impulse-radio ultra-wideband radar, it was connected to an NVA-R661 module.

In this paper, a quasi-Yagi antenna for an indoor location tracking system is proposed. The performance of the proposed antenna was verified by testing it using an indoor location tracking system. To improve the bandwidth and gain, two parasitic directors were added near the dipole. The performance verification of the proposed antenna is explained, along with a performance comparison of the VSWR (voltage standing wave ratio) radiation pattern and the realized gain. The proposed antenna was connected to an NVA-R661 module of Xethru Inc. for indoor location tracking. The proposed antenna exhibited a wide bandwidth of 4.36 GHz by satisfying a VSWR ≤ 2 from 5.03 to 9.39 GHz, the maximum gain was 6.46 dBi in the 8 GHz band. The radiation pattern exhibited a good directivity characteristic within the proposed band. The location tracking result of a moving target clearly describes the route of the target along a moving line.
