Design and Simulation of Microstrip Antenna Array Operating at S-band for Wireless Communication System

“…Moreover, the width of feed line (W f ) can be obtained from input impedance equations as mathematically expressed by [9] as: (8) where, (Z ∘ ) is the antenna impedance, and for transmission line feed is equal to 50 ohms, while, the characteristics impedance (Z ∘ ) of the two microstrip lines is given by [6] as: (9) Moreover, the length of the inset-fed line is specified by [7]: (10) Depended on the above equations, the single RMSA dimensions after optimization through the mentioned simulation methods are determined and the results are summarized in the Table 1.…”

“…Many studies were published in the literature proposing different feeding methodologies, slots, defected ground plane, various antenna arrangement arrays to achieve antenna improvement characteristics [6,7]. Among these methods, the MSA arrays of various geometrical construction have been increasingly employed in recent years, since they are durable and provide very attractive performance for several application systems such as, 5G, satellite, medical applications, WLAN, radar, personal technology and military application systems [8][9][10].…”

“…It was found that the proposed antenna provides a gain, efficiency and bandwidth of the order of (4.2 dB), (82%) and (19 MHz), respectively. A RMSPA gain improvement through an array of (4x1) configuration operating at (2.5 GHz) was designed and simulated on the FR4 dielectric substrate of thickness (1.6 mm) making it reliable for WiMAX applications [7]. Besides, a higher radiation performance for an inset fed single element, (1x2) and (1x4) arrays RMSPA placed on Rogers-RT-5880 with thickness (1.6 mm) operating at (2.4 GHz) for WLAN applications was achieved by [12] using IE3D numerical method.…”

Optimization of Microstrip Patch Antenna for Wireless Communication

“…In this study, the Rogers RT/duroid 5880 substrate was due to its favorable dielectric constant (εr ≈ 2.2) and low-loss tangent (tan δ ≈ 0.0009) at the target frequency range. This substrate material offers excellent impedance matching and radiation efficiency, contributing to enhanced overall antenna performance [14] Using transmission line theory the dimensions of the antenna were estimated for this work [1], [15], [16]. The dimensions a single patch are shown in Table 1 and the structure is depicted in Figure2.…”

“…In recent years, seamless integration into devices has been made possible by the evolution of antennas in contemporary communication from massive to compact designs like microstrip patch antennas [1]. This progression highlights how important a role they play in balancing size and performance for wireless communication.…”
