A wirelessly powered Internet-of-Things (IoT) sensor system is presented in this paper. It is facilitated by a highly compact, planar electrically small Huygens rectenna. The rectenna is based on two metamaterial-inspired electrically small structures, an Egyptian axe dipole (EAD) and a capacitively loaded loop (CLL). The near-field resonant parasitic EAD and CLL structures are carefully designed to be a compact entity that excites a short dipole. A highly efficient rectifier circuit is seamlessly connected to this driven dipole, forming a rectenna. The whole rectenna system is fabricated on a single piece of PCB substrate. It is electrically small, has an ultra-thin profile, and is low cost and lightweight. The developed rectenna is able to wirelessly power IoT devices to realize battery-free systems. A wirelessly powered light detection sensor system is successfully demonstrated by augmenting the rectifier with a photocell.

In this paper, a dual-polarized aperture-coupled microstrip patch antenna array with a high-gain high-isolation low cross-polarization levels, and low-backward radiation level is designed and its features are presented. The proposed configuration allows the scalability of the array size with daul polarization feeding network at two different layer. The antenna uses the slot-coupled feed for one polarization, while the microstrip line feed with slotted ground plane is used for the other polarization. It can make good use of the space on both sides of the ground plane, as the feed circuits for two orthogonal polarizations are placed on each side of the ground plane, respectively. Dielectric lens is used to improve the gain of small size array performance. The proposed 16-element array is presented at mm-Wave applications yields a bandwidth of more than 12.6%, with high-gain around 30 dBi and isolation below 35 dB. High gain with good isolation are obtained, and the cross-polar levels are below −33 dB at both E-plane and H-plane.

Monopulse tracker is well-known for using the sum and difference radiation patterns for track, typically done electronically. The objective of this work is to create a dual band all-passive antenna array with composite right hand feed transmission lines to obtain the sum and difference patterns. A dual-band Wilkinson power divider has been designed for inphase output at 2.6 GHz and a phase difference of 180° at 1.8 GHz achieved by using a CRLH transmission line in one of the output arms. This is incorporated in a microstrip feed system to obtain the sum and difference patterns. Design optimization has been done using ANSYS HFSS. The antenna array has been fabricated and the sum pattern has been validated. Work is in progress to validate the difference pattern.

LTE for Railway (LTE-R) system will be deployed at 460MHz frequency band to meet the user requirements of intelligent railways. To evaluate the coverage quality of LTE-R, a multi-carrier system operating over frequency selective channels, we investigate channel frequency domain correlation properties in a high-speed railway scenario at 460MHz. Based on the measurements, the received power of each subcarrier are modeled as Nakagami-m channel model which characterizes the small-scale fading distribution over time domain. Based on the modeling results, the correlation coefficients between different frequency bands are analyzed to explore statistical characteristic of different sub-carriers. Then the minimum required number of different sub-carriers for coverage quality evaluation and effective Signal to Interference and Noise Ratio (SINR) estimation of LTE-R system are suggested based on the analysis results.

This work proposes a novel method of rendering a double-stub tuner dual-band through the introduction of embedded, metamaterial-based electromagnetic bandgap structures (MTM-EBGs). The MTM-EBG, which has predictable dispersion characteristics and is both compact and uniplanar, effectively changes tuner's stub lengths as a function of frequency, allowing matching of a $50-Omega$ source impedance to an arbitrary, frequency-dependent load at two frequency bands, while maintaining a size no larger than the corresponding single-band double-stub tuners. The dual-band, double-stub matching network operates comparably to conventional single-band structures, with return loss of over 20 dB observed in each band.

Achieving high-bandwidth RF performance in electrically small and compact volumes remains a continuous challenge. The difficulty lies in the inability of electrically small antennas to radiate high-bandwidth RF signals efficiently because of their narrow bandwidth performance resulting from their high radiation Q-factors. Consequently, the RF signal is heavily distorted and/or reflected back to the source, while at the same time, the antenna suffers from minimal antenna gain. In this paper, we propose using a capacitively loaded loop antenna (CLLA) that utilizes Direct Antenna Modulation (DAM), enabling radiation of a high-bandwidth high data rate quadrature frequency shift-keyed (4-FSK) signal between 27 MHz and 39 MHz. The CLLA was integrated with two pairs of high figure-of-merit semiconductor transistors, modulating the RF signal to produce 4-FSK. The antenna ($0.009lambdatimes. 013lambda$) was prototyped and measured, showing a high-data rate 4-FSK transmission of 1.58 Mbps, beyond the inherent narrow bandwidth of the antenna. The design achieves superior high-efficiency bandwidth performance, enabling compact RF communication in electrically small volumes.

During different antenna miniaturization techniques, mechanically driven antennas have been demonstrated as the most effective method over state-of-the-art compact antennas. The magnetoelectric (ME) antennas based on a released magnetostrictive/piezoelectric heterostructure rely on electromechanical resonance instead of electromagnetic wave resonance, which results in a typical antenna size as small as one-thousandth of an electromagnetic wavelength. However, the microelectromechanical systems (MEMS) devices are very fragile and delicate due to their suspending structure. Here we show that solid mounted resonator (SMR)-based MEMS ME antennas can be realized with robust and high-gain performance. Although various packaging approaches are used to handle MEMS devices and protect them from environmental damage, these methods are complicated and high-cost. Compared to free-standing membrane ME antennas, SMR-based antennas are more structurally stable with no need for removing silicon substrate, but the design and fabrication of Bragg reflector layers must be carefully done to obtain the desired resonant frequency. In this work, 1D Mason model and 2D COMSOL finite element method (FEM) simulations were performed to design the SMR-based ME antennas. Then the in-plane radiation pattern of a fabricated antenna that operates at 1.75 GHz was characterized. Our results successfully demonstrate how to design, fabricate and test SMR-based ME antennas, which are provided with complementary metal-oxide-semiconductor (CMOS) process compatibility, size miniaturization, mechanical stability and high-gain performance. These miniaturized robust ME antennas are expected to have great influences on our future antennas for internet of things, wearable and bio-implantable applications, smart phones, wireless communication systems, etc.

A novel miniaturized leaky-wave antenna fabricated on ridged half-mode substrate integrated waveguide technology is proposed in this paper for operation at a 5G millimeter-wave band. This paper investigates the performance of ridged half-mode SIW in its near cutoff region, and presents the simulated results. The proposed antenna achieves greater than 70% miniaturization over a reference HMSIW design while maintaining comparable gain and performance.

A fluidically reconfigurable lensed antenna is reported that covers 20 GHz to 23 GHz. The antenna is a modified antipodal Vivaldi antenna element with a fluidically-loaded dielectric lens to facilitate single-element beam-steering for three discrete beam-steering states. The fluid used in this work is ethyl acetate (C4H8O2) with $epsilon_{r}=6.0+j0.059, tandelta=0.35$ at 2.4 GHz. The antenna element and lens are fabricated using a substrate with $epsilon_{r}=3.55$ and $tandelta=0.0027$. Experimental results show that the antenna can produce up to 30° of beam-steering across the band.

Increasing system requirements for 5G and beyond wireless systems translate into an increasing importance of antenna efficiency. In this paper we show that frequency-reconfigurable antennas are a very promising solution to increase the efficiency, exhibiting an upper bound on the radiation efficiency that is significantly increased compared to traditional designs. We then compare several efficiency measurement techniques, from which we can conclude that reverberation chamber measurements are an ideal solution for 5G and beyond.
