Özet
This paper presents the design and analysis of a compact slot-loaded microstrip patch array antenna operating at 33 GHz for millimeter-wave 5G applications. The proposed 2 × 2 array is implemented on a 24 × 24 × 1mm3 Rogers RO3003 substrate, featuring four slotted patches and a stub-matched microstrip feed line to ensure precise impedance tuning. Fullwave simulations conducted in HFSS demonstrate excellent impedance matching with a return loss of -35dB at the resonant frequency and -10 dB impedance bandwidth of 1.39 GHz, covering the range from 32.73 GHz to 34.12 GHz. The antenna achieves a peak gain of 11.25 dBi with highly directional radiation patterns, low sidelobe levels, and minimal backlobe radiation, making it appropriate for point to point communication links and urban small cell deployments. Electric field and surface current distributions confirm strong resonance attributed to the slot-loaded geometry. The array factor analysis validates the radiation behavior and confirms the suppression of grating lobes due to optimized inter-element spacing. Comparative evaluation against recent millimeter-wave antenna designs shows that the proposed structure offers a trade-off among gain, compactness, and frequency stability. These characteristics introduced the antenna as a promising candidate for integration into 5G FR2 transceivers, base stations, short-range high-frequency links, and compact wireless sensor platforms.
