A compact dual band antenna is designed on FR4 substrate with permeability er 4.4. The dimension of antenna is 30 X 35 X 1.5i¾?mm3. A wheel shaped antenna with slots and stubs is proposed. Coplanar wave guide feeding is made to make it simple and compact. Dual band is obtained in S11 vs. frequency plots. Lower band is obtained from 1.3i¾?GHz to 2.9i¾?GHz. The higher band is obtained from 5.3i¾?GHz to 7.5i¾?GHz. Both the bands are broad and highly useful for IoT and IoV applications. Apart from this, these bands are important for WLAN, WiFi and ISM applications. From radiation pattern plots for i¾?, i¾? = 0, omni directional patterns are obtained but for i¾?, i¾? = 90, bidirectional radiation pattern are obtained at 2.4i¾?GHz. The current density distribution on CPW fed antenna is shown and is found to be interesting for further improvements of antenna parameters.
