“…These elements transform the electrical signal into electromagnetic signals and radiate these in space and vice versa [7]. The antenna takes up the most space in the communication system chain; thus, increasing the antenna's total size makes the implementation of a wireless device difficult in a small area [8].…”

The main objective of this work is to propose an approach for improving the performance of miniaturized microstrip patch antennas (MPAs) that are loaded with a thin film consisting of a high relative permittivity material. The method uses a thin film to decrease the antenna’s resonance frequency while keeping the antenna’s patch dimensions. For the enhancement of the antenna’s performance with a thin film, the dimensions of the patch of the designed antenna are optimized utilizing genetic algorithms (GAs). The resonance frequency of the microstrip patch antenna was changed from 5.8 GHz to 4.0 GHz, and the area of the proposed antenna was minimized by around 60%, especially in comparison to a conventional antenna alone without thin film. Most of the performances of the proposed antenna such as the return loss, bandwidth, and voltage standing wave ratio (VSWR) were improved.

“…The antenna has a size of 40 × 40 × 1.6 mm 3 and exhibits narrow bandwidths (70 and 90 MHz) in its first and second frequency bands. In Reference 6, the miniaturization of a 10 × 6 mm 2 rectangular patch antenna has been achieved with an inverted “L” shaped ground plane for 5.2 to 5.8 GHz WLAN applications. A similar technique was used in Reference 7 to reduce the antenna size up to 86.72%.…”

In this article, a compact planar heart‐shaped antenna based on countersink and partial ground plane techniques is proposed to operate as a multiband device for modern wireless systems. With a surface area of 28.5 mm2, the countersink technique (CT) has been developed to achieve high electromagnetic antenna performance. The CT consists of a particular multilayer configuration that uses two distinct materials where one of them with a radiating element on its top is placed inside another. In this article, a 508‐μm thick Rogers RO4350B with a radiating patch designed on its top is thermally embedded into a 1.524 mm thick FR4 HTG‐175. The slits are used to get multiband behavior, and their combination with the defected ground structure results in about 79.58% reduction in resonant frequency compared to the conventional antenna. A mathematical model is developed to predict the resonant frequency of the proposed antenna configuration. After modeling the heart‐shaped antenna with an electromagnetic simulator, its prototype was manufactured and validated through experimental measurements. The CT considerably improved the antenna's performance compared to the use of a single layer technology for the same antenna configuration. The return loss read from −10 dB shows that the proposed antenna covers multiple modern wireless applications, including LTE bands, 5G, WLAN, WiMAX, and Unlicensed National Information Infrastructure (UNII) radio bands. Furthermore, the antenna operates as narrowband and wideband simultaneously on its lower/middle and upper operating frequency bands. A close agreement is found between simulated and measured results across all the frequency bands.

“…The demand of dual/multi-band low profile monopole antenna with wideband circularly polarized characteristics is growing rapidly in different wireless communication applications such as satellite communication, radar, and navigation systems. The circularly polarized (CP) antennas have two inherent features over linearly polarized (LP) 1,2 antennas such as (i) CP antenna has very good immunity property from multipath interference and (ii) it has also a good polarization mismatch reduction capability. However, achieving CP antenna with wide axial-ratio bandwidth in a planar monopole antenna is a challenging task.…”

Summary In this paper, a simple wideband circularly polarized monopole antenna for different wireless and satellite communication applications is proposed. The top plate of the antenna is composed of an isosceles trapezoidal patch with an inverted L‐shaped strip connected along with this. The bottom side (ground plane) has been modified by embedding two right‐angle triangular stubs for enhancing the impedance and CP performances. The proposed antenna is designed and fabricated on commercially available FR4 substrate occupying the volume of 0.525λ₀ × 0.42λ₀ × 0.0168λ₀. The −10‐dB reflection coefficient bandwidth exhibits two wide bands of 1530 MHz (2.6 GHz to 4.13 GHz) and 2040 MHz (6.93 GHz to 8.97 GHz). The measured 3‐dB AR bandwidth is 1800 MHz (6.6 GHz to 8.4 GHz), covering International Tele‐communication Union for satellite communication bands (uplink and downlink). In addition, the proposed monopole antenna has also provided good gain ≥5dBi for both the bands.
