“…It is important to note that the shape of the parasitic conductor element placed at the bottom of the dielectric material influences the results. Three shapes with the same surface area of 32.64 mm 2 have been simulated to evaluate the parasitic conductor element's effect on the antenna performance. The circular shape has a radius of 3.22 mm, whereas the square shape's edges length is about 5.71 mm.…”

“…Multiple antennas can be used to cover different frequency bands dedicated to each wireless application. However, this results into a problem of mutual coupling or isolation [ 2 , 3 ] in addition to the challenge of accommodating several internal antennas into limited space on mobile terminals [ 4 ]. Besides, a broadband antenna, covering a wide frequency range to accommodate different wireless applications in a single band, may suffer from interference problem.…”

A novel heart-shaped monopole antenna used in wireless portable communication devices is proposed and discussed in this paper. The antenna has a radiant patch surface area of 28.504 mm 2 , the physical size of 15 Â 12.5 Â 1 mm 3 , and electrical dimensions of 0.095λ 0 Â 0.079λ 0 Â 0.006λ 0 , where λ 0 denotes the wavelength of the free space at 1.89 GHz. Its prototype is printed on FR4 HTG-175, having a permittivity of 4.2 and a loss tangent of 0.019 at 1 GHz. The partial ground plane and two metallic vias connecting two open-ended branches of the slitted radiating patch to a parasitic conductor element results in about 98% miniaturization of the active patch area, as compared to the conventional antenna. The proposed antenna exhibits nearly an omnidirectional pattern in the elevation plane with a maximum radiation efficiency of 82.78% at 3.99 GHz, while a peak gain of 4.7 dBi is obtained at 6.5 GHz. The measured-6 dB impedance bandwidths demonstrate that the proposed quadband antenna operates in all the frequency bands of mobile telecommunication standards (2G/3G/4G/5G) and other applications, including WLAN, WiMAX, ISM, meteorological services, IEEE 802.11y, and C-band satellite communications. This antenna is easy to manufacture and can be used in most portable devices as a compact internal antenna. After simulating the modeled antenna using HFSS, a prototype was experimentally tested, and the measured results were compared with the data obtained by simulation. The parameters analyzed are return loss, bandwidth, and gain on all frequency bands. The fabricated prototype guarantees a minimum-10 dB bandwidth of 110 MHz and a maximum return loss of-12.2 dB, despite its low radiation efficiency of 21.43 % in the lower band dedicated to GSM applications. Furthermore, the proposed antenna operates as a narrowband and wideband.

A dual-band, Square-shaped Microstrip Patch Antenna (SMPA) with two opposite corner cuts is proposed. The presented design is suitable for 4G/LTE and Wi-Fi applications as it resonates at 2.13GHz and 2.41GHz frequencies. The FR4 substrate with co-axial feed is used for fabrication and is simulated using CST software. The simulation result provides enhanced antenna specification of return loss (-42.64&-20.13) dB, bandwidth (62.7&89) MHz and percentage bandwidth (2.94&3.69) % than the conventional antenna prototype. Furthermore, a comparative study of simulated and experimental findings is analyzed in this manuscript. Keywords: Dual-band, return Loss, Bandwidth, Percentage Bandwidth, 4G/LTE, Wi-Fi

The evolution of advancement in communication technologies and ever-increasing demand by users for compact communication devices has necessitated a shift in the design approach to achieve antenna structures that are compact and robust. Owing to the diverse communication requirements, antenna systems operating across wide bands have become a necessity. An antenna that is capable of working effectively in several bands is called wideband antenna. In this work, a bio-inspired microstrip antenna (Bi-MPA) for wideband application is proposed and simulated. The radiating patch of the proposed Bi-MPA is the shape of Carica Papaya leaf. The structure was realized through the perturbation of the circular shape patch. The proposed antenna has an impedance bandwidth of 4.3 GHz (1.9 GHz–6.2 GHz) at a return loss of 10 dB while it exhibits a narrow band at 7.2 GHz (6.99–7.44 GHz) and 9.3 GHz (9.15–9.35 GHz) bands. The gain of the proposed antenna is between 2.60 dB and 10.22 dB and the radiation pattern is quasi-omnidirectional. The proposed Bi-MPA is compact and suitable for global system for mobile communication (GSM1900), Universal Mobile Telecommunication System (UMTS), Wireless Local Area Network (WLAN), Long Term Evolution (LTE2300 and LTE2600), Worldwide Interoperability for Microwave Access (WiMAX), C-band, X-band, and sub6 GHz fifth-generation (5G) band. Our contribution to the scientific community in this work is that we have proposed a single antenna structure that is suitable for communication in all the bands mentioned in order to ensure compactness in the mobile devices as compared to base station antennas.
