Multi Resonant Structures on Microstrip Patch for Broadband Characteristics

摘要

Multi resonant structure is one of the solutions for broadband characteristics in patch antennas. Thick substrate materials with low dielectric constant are also favourable for such characteristics. In this paper, the combination of E and U shaped slots on the patch antenna along with above mentioned substrate material properties is designed, fabricated and analysed. The characteristics of the designed antenna are studied with respect to the reports like reflection coefficient, VSWR plot, and radiation pattern. The proposed antenna exhibited a wide bandwidth of 4GHz. The effect of the material properties and the physical parameters on the broadbanding are also observed.
