| Abstract: A nation's security depends largely on her ability to develop and utilize her scientific, engineering and technological capacity. The nation’s increasing dependence on information system in every sector and the plethora of information presents a great opportunity for national security management in Nigeria. Mobile communication support national security strategies: telecommunication and device – to – device communication. The PIFAs designed based on transmission line model has volume of and for and respectively. The simulated results of the PIFAs carried out with the use of High frequency structural simulator reveal that, at 1800MHz, PIFA has return loss of , bandwidth of , gain of and electric field strength of . On the other hand, PIFA at resonated at with bandwidth of gain of and electric field strength of . These designed low profile antennas are smaller than conventional PIFAs designed at the same frequencies. The proposed antennas could be employed for and Bluetooth mobile communication standards. |
