Abstract
In this paper, a conformal Printed Log periodic microstrip antenna (LPMA) is proposed for sub-6 GHz (triple band) applications. This antenna consists of twelve rectangular patch elements along with microstrip feed line and those are fabricated on a polyimide substrate with dielectric constant value of 3.3. The adaptability of the antenna is shown by bending the LPMA horizontally and vertically across the angle of 300, 450 and 600. The execution of the antenna is analysed in terms of its return loss, Gain, H-E plane patterns and efficiency. The designed antenna is capable of operating with the resonant frequencies 2.4 GHz, 4 GHz and 5.9 GHz with the gain of 8.2, 8.9&7.5 dBi respectively, providing voltage standing wave ratio (VSWR) < 2. Using CST software the designed antenna designed, simulated and the estimated results are in great concurrence with the simulation results.
