Wideband circularly polarized antennas with wide axial-ratio (AR) bandwidth and required gain are desired for point-to-multipoint communication and remote tracking applications. Two different designs of probe-fed rectangular curved slotted dielectric resonator antenna (SDRA) models are proposed in this article, one with an overall size of 50 ? 50 mm2 (SDRA-1) and the other a scaled-down version with

Antennas and propagation constitute one of the compulsory courses for students in the communication engineering program at many universities. At Universiti Malaysia Perlis (Uni-MAP), a new project-based learning (PBL) approach has been implemented in the teaching and lab instruction of this class. Besides imparting the latest antenna technology in the form of textile antennas to the students, this

The radio telescope at Parkes has been at the forefront of international research in radio astronomy since the early 1960s. It received a further accolade recently when it was honored by the award of an IEEE Milestone for its involvement in the first moon landing on 21 July 1969 (Sydney time).

There are many stimulating and rewarding career paths in antenna design. In this article, I want to highlight the one I am most familiar with, make an argument for why you might consider it, too, and provide some opinionated but tested advice for how to be successful in the field. I was fortunate enough to build and lead Apple’s antenna design team during a period of eight years. Starting with the

TechRxiv is a free preprint server for unpublished research in electrical engineering, computer science, and related technology. Powered by IEEE, TechRxiv provides researchers across a broad range of fields the opportunity to share early results of their work ahead of formal peer review and publication. Researchers are asked to upload their unpublished research.

This article introduces a low-cost time-domain near-field measurement system based on softwaredefined radio (SDR). The method is based on using a low-cost receiver to retrieve by Fourier techniques the amplitude and phase of the signal radiated by antennas. The uncertainties introduced by the receiver are modeled and compared with empirical data. Moreover, a setup based on a reference antenna is explored

The aim of this article is to show the role of electromagnetic theory in fixing the final limitations of wireless communication systems. Some examples regarding the introduction of sidelobe constraints on the fields radiated by antennas are discussed, showing the large impact of constraints on the capacity of wireless communication systems that are based on space coding. The examples are obtained using

The six articles in this special present to the antennas and propagation community some of the emerging research activities on the application of EM-based technologies in such a societally relevant topic. The articles address food industry applications as different as sensing food quality and food spoilage indicators and monitoring food items to detect contaminants.

Contamination with foreign objects is one of the main causes of customers? complaints against food manufacturers. Although different technologies are used for food and beverage inline monitoring, cases of contaminated food products still reach the market, many of which involve plastic and glass fragments. In this article, we propose the use of a microwave imaging (MWI) technology to monitor packaged

The evolution of the electromagnetic imaging technology that has enabled the quantitative imaging of the complex-valued permittivity of grains stored in silos is reviewed. The main innovations that have contributed to the advancement of electromagnetic imaging technology and facilitated the development of this particular application are described. These innovations relate to electromagnetic inverse

Fast and efficient nondestructive evaluation (NDE) methods for food control is still an ongoing field of research. We have recently proposed to combine W-band imaging with nonlinear support vector machine (SVM) classifiers to sort out healthy from damaged fruits for a single variety of fruit. We have tested it on apples and peaches separately with a mean accuracy of 96%. We have also shown the limitation

The consequences of food adulteration can be far reaching. In the past, inexpensive adulterants were used to inflate different products, leading to severe health issues. Contamination of food has many causes and can be physical (plant stems in tea), chemical (melamine in infant formula), or biological (bacterial contamination). Employing suitable sensor systems along the production process is a requirement

Intelligent packaging for food continuously generates informative digital/analog content about the contained products during their entire life span, thus becoming one of the enabling elements of the modern data-driven economy. Packaging shells for fruits, augmented with low-cost wireless sensors for the automatic estimation of the ripening grade, can reduce waste, optimize shelf exposure, suggest when

Radio-frequency (RF) energy harvesting (RFEH) and radiative wireless power transfer (WPT) have attracted significant interest as methods of enabling battery-free sustainable wireless networks. Rectifying antennas (rectennas) are the cornerstone of WPT and RFEH systems and critically affect the amount of dc power delivered to the load. The antenna element of the rectenna directly impacts the radiation-to-ac

In this article, an affordable system to demonstrate some antenna parameters is described. It consists of a transmitter (Tx) based on a voltage-controlled oscillator (VCO), a receiver (Rx) implemented with radio-frequency (RF) detectors, and a rotary mechanical arrangement based on a stepper motor. A microcontroller (?C) performs the rotation, acquires data, and manages a set of peripherals. The measurements

We review the contributions of ?ersted and Amp?re, who helped explain the magnetic effect of electric current and its resulting mechanical action. Because of their exceptional discoveries, which occurred in the summer of 1820, that year appears as an annus mirabilis in the history of the electric science.

Discusses the importance of allocating the proper amount of time to accomplish tasks and goals. To effectively prioritize your tasks and goals, you must first honestly evaluate the amount of time required for you to complete these actions and so understand your bandwidth. People tend to be overly confident in their self-awareness, which leads to the Planning Fallacy. To appropriately plan within your
