Analysis and Design of E Shaped Dual Band Microstrip Textile Antenna for Wireless Communication

The microstrip antenna play important role in wireless communication, because microstrip antennas are light in weight and compact in size. Now days, the wearable microstrip antenna is emerging technology widely used to perform the communication between the one human body to another human body and this technology is called Wireless Body Area Network (WBAN). The wearable microstrip antennas are used in various wireless applications such as medical, military and satellite etc. The geometry of the designed microstrip textile antenna consist of E shaped rectangular patch the top and the full ground plane at bottom. The dimension of designed antenna is of 35 mm × 31 mm by its width and length. These two planes are separated by the cotton fabric as dielectric material of (ɛ_r) of 1.6 and the thickness of 1 mm. In this paper the E shaped microstrip textile antenna is designed which is resonating at dual frequencies of 3.7 and 7.4 GHz with high directivity. The proposed antenna is used for wireless communication in S and C band. The proposed antenna has been simulated in CST software and the various antenna parameters such as return loss, VSWR and directivity have been analyzed.
