Abstract

To meet the demand for high gain and low sidelobe levels of array antennas in radar systems, hydrological monitoring, and next-generation wireless communication systems, this paper proposes a 24 GHz microstrip array antenna based on a series–parallel hybrid feeding network. The proposed design combines the advantages of both series and parallel feeding structures to optimize array performance while maintaining a compact configuration. Simulation results show that the antenna achieves a reflection coefficient better than −10 dB over the frequency range of 23.9–24.3 GHz, with a maximum gain of 19.58 dBi and a sidelobe level close to −20 dB. The results indicate that the proposed antenna can basically meet the design requirements for high gain and low sidelobe performance in radar systems.
