| Summary: | An antenna is one of the critical components in the tracking system. The monopulse
antenna utilizes two beams, namely sum and difference, resulting in high accuracy
and efficiency in determining the distance and position of a target. The monopulse
antenna system consists of a radiation component and a feeding network, a hybrid
junction is a type of coupler with four ports widely used as a feeding network to
produce sum and difference beams. This research discusses a hybrid junction based
on Substrate integrated waveguide (SIW), especially Magic-Tee. SIW is proposed
to overcome bulky structures in conventional waveguides and complex integration
in narrow spaces. In this research, the design, simulation, and realization of an
SIW-based feeding network for monopulse antenna operating at the S-Band
frequency with a center frequency of 2.4 GHz are carried out. The realization of
the proposed monopulse antenna feeding network is utilizing 1.524 mm thin Rogers
RO-4003C dielectric substrates. The simulation results and realization show that
that the feeding network can provide good isolation ? 10 dB, with an insertion loss
of ? 3dB, a return loss that is ?10 dB on all ports, and a phase difference of 180°
with an error of ± 5°. |
