Summary:Two substrate integrated waveguide (SIW)-based antennas for the application of software-defined radar are proposed and investigated herein. It is usually well known that SIWs are easily integrated, lightweight, have low insertion loss, and low interference levels compared to conventional microstrip structures. The primary function of the proposed antennas is to transmit continuous waves for indoor motion detection, with the lowest amount of loss and an appropriate amount of gain. Moreover, the results of this study show that the size of the antenna can be reduced significantly (i.e., by about 40%) by applying a meander line structure. The operating frequencies of the proposed antennas are both within the industrial, scientific, and medical band (i.e., 2.4-2.4835 GHz). Measured results of return loss are -16 dB and -20 dB at 2.435 GHz and 2.43 GHz, respectively, and the measured gain is 8.2 dBi and 5.5 dBi, respectively. Antenna design and verification are undertaken through commercially available full electromagnetic software.
