“…The performance of the transmission line on the PEC plane is compared to those on a simplified liquid phantom [20] and a body model [21] instead of a real body with the same distance of l = 7 mm. The simplified liquid phantom and the body model with electrical parameters are shown in Figs.…”

A segmented coplanar waveguide (SCPW) is presented in this paper to improve the propagation characteristics of on-body communication. The SCPW is connected electromagnetically by two half-wavelength resonators arranged on both sides of the center line. The resonators provide the function to couple the SCPW with the top and bottom antennas at arbitrary positions along the line, which is a unique feature of the proposed geometry. The basic performance of the SCPW was confirmed at 5.12 GHz by a thin dielectric substrate and at 2.45 GHz by a flexible paper substrate with a silver-ink conductor. The propagation loss is reduced more than 20dB by this SCPW in on-body communication between abdomen and back sides, which is confirmed by the measurement using a phantom.

“…Theoretically, the antenna changes its effective length when the antenna is bent. The bending on the antenna increases, the effective length is decreases along and the resonant frequency will shift to a higher band [7]. Table 1 show that the bandwidth is large (in GHz) due to the low permittivity of the dielectric substrate [2].…”

Smaller designs of antenna usually implemented on Wi-Fi modules or navigation system devices which requires smaller bandwidth such as Planar Antenna. There are some antenna application requires bent antenna such as wearable UWB antenna but the substrate used will have some defects after bending and crumpling from time to time. What if the planar antenna is designed that it can be bent and the bending affects the impedance matching and shift in resonant frequency? So, this research aims to achieve the limitation of the planar antenna to be bent at certain angle and given frequency range (1-8 GHz). The planar antenna is designed in the Computer Simulation Technology (CST) Software and the proposed antenna is then bend in the simulation software. The analysis of comparative evaluation for both planar and bent antenna is carried out on different characteristics such as evaluation between S-Parameters & Frequency and evaluation between Voltage Standing Wavelength Ratio (VSWR) & Frequency. The behaviour of radiation pattern for both antennas can also be obtained in the CST simulation.
