Design of EBG using Double Interdigital Coplanar Waveguide Structure for Reduced Size and High Gain Antenna

摘要

A new Mushroom-like Electromagnetic Band Gap (EBG) structure with double interdigital coplanar waveguide is proposed. The proposed structure has a fundamental frequency of 1.8 GHz and a size of λ/8. An array of 10×10 unit cells is designed to serve as a reflector to increase the gain of a dipole antenna. The antenna gain is increased to 7.98 dBi. The directivity of the antenna is increased to 7.82 dBi.
