Development of Novel Design to Enhance the Characteristics of Flexible Antenna

2. Antenna Design Procedure

This paper presents the design of proposed antenna geometry and analyzed on simulation software. The antenna geometry consists of conducting patch, dielectric substrate material and a partial conducting patch used as ground plane. The copper is used to form the ground plane and radiating elements of the anticipated antenna. CST is used to simulate the anticipated design. Fig.1 illustrates the design of flexible antenna consist of partial ground, made of copper adhesive tape of thickness 0.038mm and substrate is made of jeans with thickness 1mm.The proposed antenna provides triple band and hence suitable for wireless communication system. The dimensions of ground are 30 mm and 86 mm. The general permittivity of jeans substrate is 1.7 with tangent digression of 0.025.The radius of patch is 14 mm with two square slots with measurement 5x5 mm and the width of feed line is 2 mm.

3. Results And Discussions

The anticipated antenna features has been analyzed and studied. Fig.2 shows return loss Vs frequency plot with triple band at 6.8086GHz, 9.5952 GHz and 13.044GHz respectively. The 3D characteristics of proposed antenna are shown in Fig.3 which shows directivity 3.953dBi, 5.017dBi and 6.437dBi. Fig.4 explains the polar characteristics of the anticipated antenna at resonant frequencies 6.8086GHz, 9.5952GHz and 13.044 GHz respectively.
