SummaryThis research describes the detailed analysis and design of the compact complex‐free structural metamaterial quad band radiating element applicable for Bluetooth, WiMAX, WLAN, and fixed‐satellite service. The radiating element designed is composed of an inner angle‐rotated circular Split Ring Resonator (SRR) placed within the outer square‐shaped SRR interlinked by a strip to design the multiband operational characteristics and is fed by a coplanar waveguide. Suggested radiating element is imprinted over the FR4 substrate material with the electrical dimension of 28 × 31.26 × 0.8 mm3. The initial outer‐closed square ring offers dual‐band operation by resonating at 2.8 and 8.5 GHz frequencies, and the incorporation of a circular SRR offers quad‐band operation. The unique negative permeability feature of the proposed Square and Circular Split Ring Resonator (SCSRR) structure is extracted, and its band characteristics are analyzed. Results obtained from the simulated radiating element are validated with the fabricated antenna. The measured E plane pattern resembles a numeric eight shape, and the H plane pattern is omnidirectional. Suggested SCSRR antenna offers a gain of above 3.2 dBi in all the operating bands.

A broadband compact Y shaped monopole antenna with band-notched characteristics is designed and investigated. The antenna structure is based on the defected ground with slit resonating structures. The ground plane is loaded with two hook shaped slots on the opposite edges along its width. One horizontal slot and one vertical slot are also etched on the ground plane to improve the impedance matching for the design to resonate in Wi-MAX and WLAN wide bands. It operates at the frequencies of 2.68 GHz, 3.75 GHz and 5.72GHz for WLAN and Wi-MAX applications. The compact antenna has a size of 30×30×1.59 mm 3 and stable radiation patterns are obtained at resonant frequencies.

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
