“…Our proposed design seems simple after all these literary works are compared, but all resonating bands belong to the same application area. Apart from these, our proposed antenna design is better than other designs available in the literature [19][20][21][22][23][24]. Out of its three resonance bands, the band resonating at 3.48 GHz generates a fully circularly polarized wave.…”

This paper proposes an orthogonal dual-feed microstrip patch antenna (MPA) that achieves multi-band resonance along with circular polarization at its primary band of 5G cellular communication. The proposed antenna is simpler than other designs to fulfill extreme data rates and minimum infrastructure requirements. This MPA is designed by taking most care for maintaining the isolation between ports with feasibility for physical fabrication. The HFSS based optimally designed proposed MPA resonates simultaneously at 3.48 GHz (3.3 GHz-3.7 GHz) band, 6.24 GHz (5.925 GHz-6.425 GHz) band, and 7.5 GHz (7.11 GHz-7.9 GHz) bands. The modes achieved for these three bands are TM 01 , TM 11 , and TM 12 for 3.48 GHz, 6.24 GHz, and 7.5 GHz, respectively. The bandwidths achieved for the bands mentioned above are 160 MHz (4.57%), 330 MHz (5.27%), and 340 MHz (4.53%), respectively. The corresponding gains achieved are 9.8 dB, 5.06 dB, and 7.58 dB. The proposed MPA structure prototype is fabricated, and its performances are measured. The measured S 11 for fabricated MPA is close to the resonating frequency found using HFSS simulation. The proposed MPA structure is also modeled and simulated in a MATLAB simulation environment. Performance parameters of the proposed MPA obtained in MATLAB and HFSS are compared and matched reasonably. The proposed MPA structure and its arrays are used for 5G cellular sites as a real-time application in a MATLAB simulation environment. Different test scenarios are created in MATLAB. SINR is visualized for the entire cellular area, and signal strengths are also fetched at the receiver sites.

“…All these factors favour the examined antenna, particularly with a wide passband reconfiguration. The examined antenna is substantially denser in terms of dimensions than the antennas reported in [18,[21][22][23][24][25][26][27][28][29][30][31][32][33][34]. The impedance bandwidth obtained from the studied antenna is as per the requirements given by the FCC for 5G applications, which is 25% of the central frequency.…”

A compact (25×28×1.57 mm 3 ) and wide-band multimode frequency tunable antenna with a defected ground structure (FRDGS) for 4G and 5G conformal portable devices and multi-band wireless systems is presented in this article. In a previous study, frequency reconfigurable antenna designs only used the method of adding slots on the patch or ground. In this study, a combination of multiple slots, partial ground, and defective ground structure techniques are utilised to attain the advantages of compactness, wide impedance bandwidth, and steady radiation pattern. Multiple slots on the top layer of the substrate and F-shaped slot etched at the bottom make the proposed antenna. Two PIN diodes are inserted in the F-shaped slot for frequency reconfiguration, allowing the antenna to switch between different resonances. Ansys high frequency structure simulator 15.0v is used to simulate the antenna parameters. This antenna performance is demonstrated using measured and simulated data. The simulated and measured results clearly show that the proposed antenna can switch among six dissimilar resonant frequency bands via various modes of operation across the frequency spectrum from 2.3 to 8.9 GHz. The antenna works in a variety of commercial bands, such as WLAN/Bluetooth (2.4-2.5 GHz), LTE/4G (2.3-2.7 GHz), S-band (2-4 GHz), Radio Navigation (2.7-2.9 GHz), and 5G/sub-6 (3.3-4.9 GHz), according to simulations and experiments. The proposed design features narrowband, wideband, and ultra-wideband properties with a consistent radiation pattern, adequate gain (1.6 to 5.8 dB), and high radiation efficiency (86 to 94%) in a small package. Furthermore, the performance comparison of the proposed antenna with that of the state-of-the-art antennas in terms of compactness, frequency reconfigurability, number of operating bands, and impedance bandwidth demonstrates the novelty of the proposed antenna and its potential application in multiple wireless applications.

In this paper, a low-profile, compact size, inexpensive, and easily integrable frequency reconfigurable antenna system is proposed. The proposed antenna consists of an inverted-F shape antenna, capacitors, and switching PIN diodes. The designed antenna element is fabricated on easy available and less expensive FR-4 substrate ( ε r = 4.4, tan δ = 0.02). The switching diodes are incorporated within the radiating structure of the antenna design, and by changing the different states of PIN diodes, frequency reconfigurable response is achieved. While adjusting the different states of the diodes, the antenna resonates between 0.841 GHz and 2.12 GHz and covers six different frequency bands. The proposed system has compact size of 44 × 14 × 3.2 mm 3 . The gain of the antenna is between 1.89 and 2.12 dBi. The measurement results shows the good agreement with simulated results for different key performance parameters. Additionally, the proposed antenna shows omni-directional far-field characteristics for various different frequencies.
