Author Name:Shankul Saurabh and Rajan Mishra
Synopsis:

A multi band meander line antenna is proposed in this paper for ISM and Ultra Wide-Band (UWB) applications. The size of the antenna is 60x40x1.6 mm3. FR4 Epoxy having dielectric constant of 4.4 and dielectric loss tangent of 0.02 is taken as substrate of the antenna. Co-axial probe feed and capacitive feed is used to excite antenna. Dual feeding is used in order to enhance the operating bandwidth and radiation efficiency of the proposed antenna. The experimental 10 dB bandwidth of 800 MHz, 2.42 GHz and 1.5 GHz can be obtained at various resonant frequencies while simulating the design on Ansoft's HFSS 13.0. The proposed antenna can be used for various applications including mobile phone communication and Ultra-wide Band (UWB) applications and also it can be used as WLAN application at 5GHz.
