“…In contrast, the gain decreases to −3.9 dBi in the stop-bands, validating gain suppression at out-of-band frequencies. In general, the gain increases in the pass-band with the increasing frequency due to the increased effective size of the antenna [33,34]. Similarly, the antenna shows a high radiation efficiency (up to 88%) at resonating bands, while it is reduced to 40% at out-of-band frequencies.…”

We designed and constructed a novel, compact tri-band monopole antenna for intelligent devices. Multiband behavior was achieved by placing inverted-L shaped stubs of various lengths in a triangular monopole antenna fed by a coplanar waveguide. The resonance frequency of each band can be controlled by varying the length of the corresponding stub. Three bands, at 2.4 (2.37-2.51), 3.5 (3.34-3.71), and 5.5 (4.6-6.4) GHz, were easily obtained using three stubs of different lengths. For miniaturization, a portion of the longest stub (at 2.4 GHz) was printed on the opposite side of the substrate, and connected to the main stub via a shorting pin. To validate the concept, the antenna was fabricated on a low-cost 1.6-mm-thick FR-4 substrate with dimensions of 20 × 15 × 1.6 mm 3 . The antenna exhibited a moderate average gain of 2.9 dBi with an omnidirectional radiations over the bandwidths required for RFID, Bluetooth, ISM, WiMAX, and WLAN-band applications. These features make the antenna suitable for compact smart devices.

The contributions of researchers at a global level in the journal Electronics in the period 2012–2020 are analyzed. The objective of this work is to establish a global vision of the issues published in the Electronic magazine and their importance, advances and developments that have been particularly relevant for subsequent research. The magazine has 15 thematic sections and a general one, with the programming of 385 special issues for 2020–2021. Using the Scopus database and bibliometric techniques, 2310 documents are obtained and distributed in 14 thematic communities. The communities that contribute to the greatest number of works are Power Electronics (20.13%), Embedded Computer Systems (13.59%) and Internet of Things and Machine Learning Systems (8.11%). A study of the publications by authors, affiliations, countries as well as the H index was undertaken. The 7561 authors analyzed are distributed in 87 countries, with China being the country of the majority (2407 authors), followed by South Korea (763 authors). The H-index of most authors (75.89%) ranges from 0 to 9, where the authors with the highest H-Index are from the United States, Denmark, Italy and India. The main publication format is the article (92.16%) and the review (5.84%). The magazine publishes topics in continuous development that will be further investigated and published in the near future in fields as varied as the transport sector, energy systems, the development of new broadband semiconductors, new modulation and control techniques, and more.

“…Since the radiating patch, feeding-line, and ground plane are all in the same plane, this leads to easy integration of microwave antennas along with all other communication parts. [5][6][7] A unique technology has been developed to miniaturize the size of the antenna without affecting any kind of other parameters concerning its geometry. This can be made possible by the application of different types of substrate material having dielectric constant ( r ) ranging in 2.2 ≤ r ≤ 12.…”

This paper presents a miniaturized rectangular CPW‐fed microstrip antenna operating at a frequency of 2.4 GHz covering the bandwidth of 1.4 to 3.1 GHz, suitable for WLAN/ISM application. In this work, the effects of different geometrical shapes and substrate materials on the performances of the antenna have been investigated to select its structural size, shape, and substrate material to achieve their overall reduction in the size of the area, and the desired performance characteristics. The choice of suitable substrate materials and its growth position about ground terminals T1 and T2 affects the performance of the CPW antenna. Appropriate selection of dielectric substrate materials such as Flame‐Retardant Epoxy (FR4), Arlon (AR 600), Aluminum Nitride (AN), and Rogers (RO TMM 10i) for proposed Type‐I, Type‐II, and Type‐III antennas, respectively, are important parameters for designing and implementing a CPW patch antenna. This work investigates the change in antenna performance when the substrate dielectric materials are varied. The achieved miniaturization in terms of area percentage is as high as 55% of a proposed Type‐II (RO TMM 10i) antenna for wireless local area network (WLAN, 2.400–2.484) or industry science and medical (ISM, 2.400–2.480) band application. A detailed study for different dielectric substrate material of different geometrical shape and size has been performed and mentioned in this paper.
