Effects of Split Ring Resonator (SRR) Metamaterial on the Radiation Pattern and Variation of the Heating Focus Point of the Microstrip Patch Antenna

by Mahsa Jahangiri and Saman Rajebi

Advances in Science, Technology and Engineering Systems Journal, Volume 5, Issue 1, Page # 307–316, 2020; DOI: 10.25046/aj050139

Abstract:

Metamaterial antennas are some sort of antennas which utilize metamaterials to improve the efficiency of small (small electrical) antenna systems and also enhance the antenna’s radiation pattern. The unusual properties of metamaterials such as coefficients of permittivity and permeability, as well as the negative refractive index, have led to increase the use of these artificial…

Novel Design of Multiband Microstrip Patch Antenna for Wireless Communication

by Youssef Rhazi, Outman El Bakkali, Youssef El merabet, Mustpaha Ait lafkih, Seddik Bri and Mohamed Nabil Srifi

Advances in Science, Technology and Engineering Systems Journal, Volume 4, Issue 3, Page # 63–68, 2019; DOI: 10.25046/aj040310

Abstract:

This paper presents a novel six band frequency reconfigurable antenna for 2.4 GHz (Lower Worldwide Interoperability for Microwave Access (WiMAX)), 5.3 GHz (Wireless Local Area Network (WLAN)) and 9.1-10.2 GHz (X-band) frequency bands. The proposed antenna has a compact size of 22mm_30mm at lower resonance of 4.2 GHz and is printed on FR4 material with…
