ABSTRACT: 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.
