“…Recently, researchers have focused on developing new designs of the MPA, including the shape of the radiator element [12] (such as a rectangle, a square, a triangle, a circle, a ring, or a heart [13]), the operating frequency [14], [15] (such as 2.4 GHz, and 5.8 GHz), the polarization (linear [16] or circular [17]), and miniaturization methods (defective ground structure (DGS) [18], defective microstrip structure (DMS) [19], and electromagnetic bandwidth structure (EBS) [20]). Some work in the literature where the operating frequency is about 2.45 GHz like [21]- [24], the bandwidth of this work is less than 68.80 MHz. In this context, this work was done to have a wide bandwidth around the resonant frequency of 2.45 GHz.…”

<p>This paper provides a new conception for a microstrip patch antenna array that operates in a circularly polarized manner for wireless power transmission (WPT) at 2.45 GHz. The proposed conception combines four pentagonal patches and the defected ground structure (DGS) method. The antenna array with a dielectric constant of 4.4 and a tangential loss of 0.025 is printed on a FR4 where its thickness is about 1.58 mm. The developed design aims to optimize the antenna array performance. Th e main contribution, to the telecommunications and WPT fields, is to achieve a maximum energy transfer with low losses, while also ensuring adequate adaptation to the excitation port. To prove the effectiveness of this design, simulation results were obtai ned using computer simulation technology microwave studio (CST MWS) software and validated by another solver high - frequency structure simulator (HFSS). Simulation results are presented and compared with those obtained using existing conceptions in the lite rature. The proposed design has proven to be very effective in achieving the intended objectives, which makes this design very good for radiofrequency (RF) energy collection and its various applications to power a variety of devices without harming our pla net.</p>

“…Table2helps us to make a comparison between the developed design in this paper and other works in the literature. Based on Table2, the proposed conception of the 1×4 MPA array is more performant than the other cited work[21]-[24]. Thanks to its utility of four elements, its smallest surface, its greater gain, and its largest bandwidth.…”

“…Due to their low profile, compactness, robustness, and ease of fabrication, patch and slot antennas represent the best choice for connecting CubeSats into orbit with the ground station on earth. They also present low radiation loss, low dispersion, easy matching of input impedance, and are available commercially [9][10][11]. However, their main drawback is their low peak gain at an operating frequency.…”

Among other CubeSat subsystems, Antenna is one of the most important CubeSat components as its design determines all the telecommunication subsystems’ performances. This paper presents a coplanar wave-guide (CPW)-fed equilateral triangular slot antenna constructed and analyzed for CubeSat communications at S-band. The proposed antenna alone presents high gain and ultra-wide band while its radiation pattern is bidirectional at an unlicensed frequency of 2450 MHz. The objective is to use the CubeSat chassis as a reflector for reducing the back-lobe radiation and hence minimizing interferences with electronic devices inside the CubeSat. This leads to a high gain of 8.20 dBi and a unidirectional radiation pattern at an industrial, scientific and mdical (ISM) band operating frequency of 2450 MHz. In addition to that, the presented antenna is low-profile and exhibits high return loss, ultra-wide impedance bandwidth, and good impedance matching at 2450 MHz.

“…In RFID systems, antennas are used in Tags and readers and provide an important concern for the detection system of objects. [14][15][16][17]. Many researchers have investigated different microstrip 1×2 array antenna for RFID applications that offers maximum gains of about 4.73dBi [18], 6.6 dBi [19], and 9.36 dBi [20].…”

In this paper, a printed 1×8 array antenna operating at 2.4 GHz is proposed for radio frequency identification (RFID) Reader. The proposed array antenna is composed of eight identical modified patch elements. The radiating elements are fed in parallel via a simple 50 Ohm microstrip line matched with a quarter-wave impedance transformer using a T magic power divider to divide the input power into two equal quantities with the same phase. The suggested array configuration is designed using Rogers RT/duroid 5880 substrate having dielectric constant εr = 2.2, dielectric loss tangent = 0.0009, and substrate’s height of 1.56mm. The overall dimension of the 1×8 array antenna is 117×475mm2. The proposed array antenna shows good impedance matching, high gain and directional radiation patterns. The proposed array antenna has a high gain about of 14.61dBi, high radiation efficiency of 98.3%, and a good reflection coefficient S11 of -13.14dB and voltage standing wave ratio (VSWR) of 1.56 at 2.4 GHz.
