This article presents the designs of planar inverted-F antennas (PIFAs) at frequencies of 0.835 GHz, 0.9 GHz, 1.8 GHz, 1.9 GHz, 2 GHz, and 2.6 GHz. Initially, the designs of rectangular-shaped PIFAs are determined through the parametric studies concerning the dimensions of the antenna’s patch length, shorting plate, ground plane, and substrate. Afterward, rectangular-shaped slots are introduced into radiating element of two antennas that operate at a lower frequency range of less than 1 GHz, to tune the resonant frequency to the respective 0.835 GHz and 0.9 GHz. Different configurations of partial or full ground plane are implemented to improve the reflection coefficient, S11 performance to be below -10 dB in both simulation and measurement. The proposed six PIFAs have gain that are greater than 2 dB with the nearly omnidirectional radiation patterns. All the designs and analyses are performed using the CST Microwave Studio utilizing Rogers 4003C substrate.

This article presents the investigation of specific absorption rate (SAR) of a rectangular-shaped planar inverted-F antenna (PIFA) at frequency of 2.6 GHz. Initially, the design antenna is presented with parametric study concerning the dimensions of antenna patch length, shorting plate, ground plane and substrate. The proposed PIFA antenna has -20.46 dB reflection coefficient and 2.383 dB gain. The PIFA’s SAR is correlated with the antenna gain and excitation power. The analysis shows that higher gain contributes to a lower SAR value. While, the higher excitation power causes a higher SAR value. All the design and analysis are performed using the CST Microwave Studio

Authors designed an obstacle radar transceiver for ISM band. This work is focused on rectangular microstrip transceiver integrated with innovative metamaterial structure at a height of 3.276 mm from the ground plane. Two rectangular microstrip transceiver is designed for transmitting and receiving purpose. This work is mainly focused on increasing the potential parameters of rectangular microstrip transceiver. RMT along with the proposed innovative metamaterial structure is designed to resonate at 2.259 GHz. Simulation results showed that the impedance bandwidth of the RMT is improved by 575%, return loss is reduced by 391% and efficiency is improved by 28% by incorporating the proposed innovative metamaterial structure. For verifying that the proposed innovative metamaterial structure possesses negative values of Permeability and Permittivity within the operating frequency range, Nicolson-Ross-Weir method (NRW) has been employed. An op-amp and comparator is used to compare the return loss of transmitting and receiving RMT. An indicator is used to indicate difference of return loss and power of transmitting and receiving rectangular microstrip transceiver. For all simulation purpose, computer simulation technology-microwave studio (CST-MWS) software has been used.
