Performance enhancement of patch antenna array for 5.8 GHz Wi-MAX applications using metamaterial inspired technique

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.

To prevent far-field radiation characteristics degradation while increasing bandwidth, an attempt has been made to design and fabricate a microstrip antenna. An electromagnetic band gap (EBG) structure, including a layer of a metallic ring on a layer of Rogers 4003C substrate, is used. For a better design, a patch antenna with and without the EBG substrate has been simulated. The results show that the bandwidth can be improved up to 1.6 GHz in X-band by adding the EBG substrate. Furthermore, using this structure, a dual-band antenna was obtained as well. Finally, to validate the simulation results, a comparison has been done between simulation data and experimental results which demonstrate good agreement.

We have developed a compact antenna for wireless applications with a new shape and special attribute. It is a dual‐band antenna with a second harmonic characteristic. The antenna has a special shape of the dielectric resonator with metamaterial meandered composite right/left‐hand (CRLH) structure. The Microstrip ring antenna is the right‐hand part. We used the Microstrip meandered line via inductance for the unit cells to achieve a circular polarization and to change the current distribution at the surface of the antenna. We added a parasitic ring to the antenna to achieve the second harmonic resonance. We have connected three unit cells at the 120° angle. This special shape provides the circular polarization and compact size. The antenna has quad‐band at the first harmonic, and the resonances occurred at 2.25 and 2.8 GHz. The second harmonics happened at 4.5 and 5.6 GHz.
