Bourdon tube, an indicating type pressure measuring instrument is used as a local indicator and display unit. Hence a special technique is needed to transmit and to display the reading of a bourdon gauge at remote location. In this paper, a modified bourdon tube has been proposed which is capable to transmit the measured pressure information via optical domain by employing the method of electro-optic...
A wide band metamaterial based electrically small Lshapedmonopole antenna is proposed for the application of Wimax and Wifi. It is easy to fabricate due to planar and compact structure. The coplanar waveguide (CPW) feed is used to provide better bandwidth. The bandwidth of the proposed antenna is 2.5789 GHz. Compactness of antenna is achieved by using ring resonator having a metamaterial property.
