CSRR Loaded Multi Substrate Antenna for 4G LTE and Wi-MAX Applications

This paper examines the Dual Layer substrate with Dual patch Microstrip antenna (DLDM). Radiation characteristics of dual substrate antenna with active E-shape patch between the substrates and passive complementary strip ring resonator loaded Microstrip Patch Antenna (MPA) is analyzed. Because of this dual layer substrate miniaturization of antenna is reported. Multi band frequency resonance and shift in the resonant frequency is possible with Complementary Split Ring Resonator (CSRR) loaded passive patch. Comparison of normal E-shape patch and DLDM are studied, and results are discussed. This structure provides ~9.0 dBi gain with triple band resonance which can be used for 4G LTE and Wi-MAX wireless LAN applications.
