“…To highlight the originality of the proposed work, Table 2 shows a comparison of the performances of the previously related works and the proposed one. The proposed antenna has a more compact size and wider operating bandwidth than the other MIMO antennas reported in [7][8][9][10][11][12][13][14][15][16][17][18]. Also, the proposed antenna has provided better isolation than [8,9,11,14,16].…”

“…Two rectangular strip lines located diagonally opposite the DR's edges stimulate a rectangular DR. To generate the circular polarisation, the ground plane is modified by etching an inverted Z-shaped slot. In [17], a UWB MIMO configuration with a rectangular DR is presented. For UWB applications, a coplanar waveguide (CPW) fed stair-shaped dual rectangular dielectric resonator antenna (RDRA) with different permittivities is developed.…”

In this communication, a new compact UWB dual port multiple-input multiple-output (MIMO) antenna is presented for wireless application. The design utilizes the property of dielectric resonator to achieve a bandwidth that ranges from 3.1 GHz to 18.5 GHz. The design has a compact size of 19 × 30 × 0.8 mm 3 . It consists of two rectangular shape monopole antenna elements with rectangular dielectric resonators sharing a similar ground plane. On the ground plane, a modified Hilbert curve with a meander line parasitic element was introduced to improve isolation between radiating elements which reduces mutual coupling issues. A band notch is achieved at WLAN band (5.09-5.8 GHz) by etching a pair of L-shape slots on each radiator. The gain of the antenna drops significantly at the centre of the notch band which indicates good interference suppression. Results show that the designed antenna provides a wide impedance bandwidth (below −10 dB) throughout the operating band of 3.1-18.5 GHz (142.6%). The antenna also produces nearly −20 dB isolation for the entire operating band. Results show that the simulated characteristics are in good agreement with the measured counterpart.

“…As another approach, recent developments in inexpensive ultrawideband (UWB) transceivers have enabled highprecision time-of-arrival (TOA) or time-of-flight (TOF) measurements in wireless communications [17]. Low-power UWB communication is a communication standard in which wireless impulses can be continuously transmitted and received to achieve precise localization and tracking at a level of several centimeters over a short distance [18]. The frequency band used is 3.1-10.6 GHz, and the operating distance is approximately tens of meters.…”

Recently, interest in ultrawideband (UWB)-based localization systems has increased in various application fields. However, since UWB anchors are usually fixed, they work only within the limited range that UWB measurement signals can reach. To address this issue, a swarm flight system with movable UWB anchors is developed. One ground station controls multiple unmanned aerial vehicles (UAVs), each of which is equipped with a UWB anchor and real-time kinematic global positioning system (RTK-GPS) capabilities, and collects the precise (centimeter-level) positions of the UWB anchor UAVs through RTK-GPS. In this way, the constraints of existing UWB systems can be alleviated by changing the UWB anchor positions in real time as desired by the user. In addition, this paper proposes a novel localization algorithm using only time-of-flight (TOF) measurements from UWB signals, heading information from an attitude and heading reference system (AHRS), and altitude information from a barometer. The results of UAV flight tests show that the proposed algorithm provides better localization performance than existing algorithms.INDEX TERMS Interacting multiple model, Kalman filter, localization, swarm flight system, ultrawideband (UWB), unmanned aerial vehicle (UAV).

“…With the fast advancement of present‐day wireless communication technology, as well as navigation and radar systems, a circularly polarized (CP), ultra‐wideband (UWB) antenna with a small footprint is required to a greater extent 1,2 . However, the majority of UWB designed so far were linearly polarized.…”

In this article, a circularly polarized dielectric resonator antenna is designed with ultra-wideband (UWB) features. The structure comprises a cross-shaped multilayer multipermittivity (MLMP) rectangular dielectric resonator, a chimney-shaped patch, and an air gap between the ground plane and the dielectric resonator (DR). To obtain the UWB, the upper layer of DR is rotated around the z-axis. The proposed antenna has measured UWB bandwidth of around 179.4% (0.8-14.8 GHz) below −10 dB, with three bands of 3 dB axial ratio bandwidth of 97.8% (1.0-2.8 GHz), 38% (5.65-8.3 GHz), and 20% (12.1-14.8 GHz), respectively. The average gain of the proposed antenna is 5.64 dBi, which is consistent with the hardware measurements. The proposed antenna is suitable for covering the ultra high frequency (UHF) to Ku microwave frequency band.
