“…In Section 3, the parametric analysis is done to determine the various critical values of the proposed antenna. It is also validated that the multiband operation [39][40][41][42][43] is due to SRR and CSRR in Section 4. In Section 5, the simulated results are compared to the measured ones, followed by the article conclusion in Section 6.…”

In this paper, a Rectangular Monopole Antenna (RMPA) with offset microstrip feed is presented. The structure is fabricated on an FR4 substrate with a dimension of 28 × 32 × 1.6 mm 3 . The proposed structure achieves multiband operation by engraving 2 Complementary Split Ring Resonators (CSRRs) and a C-Shaped slot. Also, 2 Split Ring Resonators (SRRs) are printed on the adjacent sides of the radiating element. The parametric analysis is used to determine the optimum position of the feed and other critical parameters. The proposed structure operates at 2.25 GHz, 3.86 GHz, 4.60 GHz, 5.64 GHz, 5.86 GHz, 6.94 GHz, 7.48 GHz, and 9.47 GHz. The permeability of the SRR and permittivity of the CSRR are extracted and presented. The proposed antenna is fabricated and measured. The measured results of S 11 , radiation pattern, and gain are on par with the simulated results. The proposed antenna's simulated surface current and efficiency are also presented to validate the performance. Simple structure, stable radiation pattern, multiband operation, reasonable gain, and efficiency are the significant features of the proposed RMPA.

“…In [3][4][5][6][7], the compact dual-band antennas concentrate only on WLAN standards. In [8], a reflector metamaterial unit cell was demonstrated, making the dual-band operation at 5.7 GHz and 10.3 GHz with the large size of 35 × 25 × 0.787 mm 3 . In [9], a microstrip antenna was designed by metamaterial with a fractal structure of poor impedance matching of −6 dB at 2.7 GHz.…”

In this paper, a compact modified hexagonal spiral resonator-based tri-band patch antenna with an octagonal slot is presented for Wi-Fi/WLAN applications. The proposed antenna is designed on a low-cost FR4 substrate with a dielectric constant of ε r = 4.4 and a loss tangent of δ = 0.02. The tri-band operations have been achieved by a Modified Hexagonal Complementary Spiral Resonator (MHCSR) and an Octagonal slot. The loading of the MHCSR at the bottom of the substrate is to cover the 900 MHz (IEEE 802.11ah) band, and an Octagonal slot on top of the 5 GHz (IEEE 802.11a/h/j/n/ac/ax) rectangle patch is to cover the 2.4 GHz (IEEE 802.11b/g/n/ax) band. The prototype of the proposed antenna is fabricated and tested to validate the simulation results. The measured impedance bandwidth is 105 MHz at 900 MHz, 160 MHz at 2.4 GHz, and 180 MHz at 5 GHz. The designed antenna has a compact size with overall dimensions of 0.054λ 0 × 0.066λ 0 × 0.0048λ 0 (18 × 22 × 1.6 mm 3). The 82.2% reduction in size has been accomplished as compared to a conventional patch antenna at 900 MHz (lower resonance frequency). The waveguide setup method has been used to validate a negative permittivity property of the MHCSR. The parametric analysis of the proposed antenna has been carried out using the Ansoft HFSS19 software.

“…Antennas capable of radiating in more than one band are particularly useful in wearable and handheld devices because the compact size of wearable devices does not allow integrating more than one antenna for several communication channels. In literature, many researchers have introduced compact microstrip multiband antennas with various design structures [1][2][3][4][5][6][7][8][9][10]. In [1], a hexagonal inset feed radiator is used for dual-band applications, where frequency selective surface increases the antenna gain.…”

A compact multiband antenna for frequency bands of 2.45 GHz (ISM), 3.3 GHz (5G), and 5.8 GHz (ISM) is proposed. A modified Complementary Split Ring Resonator (CSRR) and crossshaped stub are introduced in a hexagonal radiator to achieve triple-band operation including both ISM bands applications of 2.45 GHz, 5.8 GHz and WiFi/WLAN. The stubs in the radiator also improve the bandwidth and impedance matching of the antenna. The 10 dB impedance of the proposed antenna varies from 2.43 GHz to 2.64 GHz, 3.02 GHz to 3.85 GHz, and 4.88 GHz to 6.82 GHz. The antenna is analyzed on a human phantom model for wearable applications, where simulated SAR and theoretically calculated SAR are 0.3251 W/kg and 0.3299 W/kg, respectively. The antenna is used on a human breast model for cancer detection applications, where the SAR value is used to analyze and validate the performance of the antenna; therefore, the antenna has effectively worked for biomedical and wearable applications.
