“…However, the drawback of this approach is that it narrows the bandwidth of the antenna and losses surface‐wave. [ 127 ] C)Superstrates: The introduction of a superstrate on a microstrip antenna is beneficial to simultaneously reduce the size and enhance the gain and bandwidth of the antenna by forming a larger in‐phase electric field on the superstrate surface. [ 128 ] D)Shorting pins: By deploying shorting pins connecting the patch and the ground plane of the microstrip patch antennas can be utilized for compressing the size of antennas.…”

Cardiovascular disease continues to be one of the dominant causes of global mortality. One effective treatment is to utilize cardiovascular implantable devices (cIMDs) with multi‐functional cell sensing and monitoring features that have the potential to manipulate cardiovascular hyperplasia disorders as well as provide therapy. However, batteries with a fixed capacity entail high‐risk surgeries for battery‐replacement, which causes health hazards and imposes significant costs to patients. This review accesses comprehensive power solutions for cIMDs, from conventional batteries to state‐of‐the‐art energy harvesters and wireless power transfer (WPT) schemes. In particular, WPT has great potential to eliminate the percutaneous wires and overcome frequent battery removal. Here, the fundamentals, power transfer efficiency, antenna design and miniaturization, and operating frequencies in various WPT schemes are presented. Moreover, the power loss attenuation and bio‐safety standard (specific absorption rate) for implants are also considered in WPT design envelope. In addition, wireless data transmission of implantable devices from external to internal milieu (and vice versa) along with different modulation and demodulation techniques are investigated. The last advanced power solutions for cIMDs in in‐vivo and in vitro research are illustrated throughout. Finally, specifications and future potential of WPT systems in cIMDs are highlighted.

“…Likewise, many advanced miniaturization techniques based on the use of high permittivity substrates and magneto-dielectric materials have gained ground in the race for antennae miniaturization methods. In [10], a high permittivity material was used on a rectangular star shape slotted MPA of dimension 28.5 ×…”

In this paper we have proposed an improved miniaturization design of a rectangular microstrip patch antenna based on Minkowski fractal. The design methodology consists in considering a rectangular patch on which the conventional and modified Minkowski curve are successively applied until the second iteration. In total, three miniaturized antennae are proposed. They are structured by a fractal patch engraved on an FR-4 epoxy substrate. Design and simulation are performed by CADFEKO 7.0.1 software, better suited for small size antennae. The proposed miniaturized fractal models operate at the same frequency F= 15.53 GHz, as the conventional Rectangular Microstrip patch antenna. Moreover, each of them enables a good impedance matching, as can be confirmed by the low return loss obtained (< -15 dB) at the same resonance frequency. The proposed antennae presented a significant size reduction of 89.76 % for Minkowski model, 88.8 % and 86% for both modified Minkowskimodels when compared to the conventional inset-fed rectangular patch antenna. Overall, our study illustrated that, after a modified Minkowski miniaturization technique was introduced a better performance and impedance matching was achieved. According to the IEEE Standard Classification of Satellite Frequency Bands, the results of the miniaturized and optimized fractal patch antenna can effectively contribute to Ku-band communications.

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.
