A miniaturized multiband printed monopole antenna is reported using hexagonal complementary split ring resonator (HCSRR) slots. Antenna miniaturization and multiband are accomplished by employing metamaterial inspired structure HCSRR. The proposed antenna consists of three HCSRR slots, it makes the antenna to resonate at 1.62 GHz, 2.4 GHz, 3.3 GHz, and 5.8 GHz frequency bands. The designed antenna structure has a small size of 20 × 20 × 1.6 mm3, which is fabricated on an FR‐4 substrate with dielectric constant |ɛnormalr of 4.4. The pass band characteristics of HCSRR are examined in detail for acquiring multiband abilities of the compact antenna, which is evaluated by use of the precise LC equivalent circuit design equations. The metamaterial property of the HCSRR is also studied to validate the resonance frequencies of the proposed antenna. Simulated and tested data are investigated. The prototype antenna has adequate advantages, with a simple structure, compact size, multiband, and uniform radiation patterns.

A rectangular monopole engraved with an open complementary split-ring resonator (OCSRR) metamaterial is designed and proposed for multiband radio applications. The proposed antenna has a rectangular monopole feed with offset microstrip feed, and the OCSRR designed at 3.14 GHz is engraved in the radiating element. The OCSRR is a special type of metamaterial with small electrical size. The OCSRR modifies the current direction due to its negative permittivity, which creates another resonance at 3.16 GHz. The left offset feed and abridged ground length creates another resonance at 3.82 GHz and responsible for good impedance matching are achieved in all the resonating bands. The entire antenna is designed and fabricated on the FR4 substrate with a complete measurement equal to 27.84 mm x 23.25 mm x 1.6 mm. The proposed structure shows the multiband characteristics at 3.16 GHz, 3.82 GHz, and 5.14 GHz with a S 11 of -19.83 dB, -17.90 dB, and -55.73 dB, respectively. The critical parameters of the OCSRR are decided using the parametric analysis, and the simulated results are presented. The OCSRR negative permittivity extraction is done with NRW wave guide extraction method, and the result is validated with the help of OCSRR resonant frequency calculation. The uniformity is well maintained between the measured and simulated results. The multiband characteristics, reasonable gain, compactness, low design complexity, and small size are the significant features of the proposed antenna

“…Many types of wideband planar antennas have been proposed in the literature, including Yshaped, ear-shaped, fork-shaped monopole antennas with meandering strips [3][4][5], CPW-fed slotloop antennas [6][7][8], proximity-coupled microstrip antennas [9,10] and metamaterial-loaded printed antennas [11,12]. However, there are still many deficiencies in the antennas mentioned above.…”

“…However, there are still many deficiencies in the antennas mentioned above. For example, only part of the band of 2.4-5.9 GHz is covered by the antennas in [3,6,11], which therefore are not suitable for broadband applications. The asymmetric structure of antennas in [4,12,13] may result in distortion of the radiation pattern and increase of the cross-polarization level [14,15].…”

A novel compact wideband printed loop antenna is presented for wireless applications. The wideband characteristic is achieved by combining three different loop resonant modes of the antenna. The antenna geometry is simple and consists of a rectangular meandering loop, a coplanar waveguide (CPW) structure, and a monopole feed. This proposed antenna has the dimension of only 27×20×1 mm 3 while operates at a wideband from 2.4 GHz to 5.9 GHz (84.3%) with stable gain, radiation pattern and vertical linear polarization. This antenna is suitable for WLAN and future 5G sub-6 GHz spectrum communications. Good agreement between the simulation and measurement is obtained.
