A Compact Dual Band Triangular Patch Antenna with Spiral Resonator for wireless applications

Main Article Content

Dr. R. Gayathri Rajaraman


A novel dual band triangular patch antenna designed using Spiral resonators (SR) in its patch is presented. The metamaterial structure (SR) used in this design effectively reduces the size of conventional patch resulting in dual resonances with wide apart spectra. The antenna is found to resonate at 10.38, 13.99 GHz with gains of 3.6 and 5.4 dBs respectively. The antenna has an Omnidirectional pattern and good directivity at the resonant bands.
