Abstract :
This paper proposes a novel compact coplanar dual band antenna for 2.4 & 5.2GHz ISM band applications. The antenna occupies an area of 25×9 mm2 on an FR4 substrate of thickness 1.6mm and permittivity 4.3. A bended dipole gives the higher resonance and an SIR, electrically coupled to the dipole gives the lower resonance. The 2:1 VSWR impedance bandwidth of the proposed antenna is 90MHz for the first resonance around 2.4GHz and 2.5GHz for the second resonance. The radiation patterns are nearly omnidirectional. The maximum measured gain is 3.33dBi and 5.9dBi for 2.46GHz and 5.42GHz respectively.
