Abstract
5G technology utilizes mmWave frequencies to support high-speed communication and large data capacities. However, a major challenge in mmWave lies in the limited bandwidth, which affects transmission efficiency. This study proposes a 1x2 microstrip antenna array with Defected Ground Structure (DGS) variations to enhance parameters such as bandwidth, gain, and S11. The antenna design employs Rogers RO4003 substrate with a thickness of 0.51 mm and is simulated using HFSS version 18.0. The methodology includes designing and simulating antennas with and without DGS, followed by fabrication and direct measurement to compare their performance. Simulation results reveal that the antenna without DGS achieves the highest gain of 10.22 dBi, while the rectangular-shaped DGS achieves the widest bandwidth of 5.63 GHz. Fabrication and measurement validate the proposed design's capability to enhance antenna performance. The findings show consistency between simulation and measurement results, demonstrating that DGS implementation significantly improves bandwidth and provides a balance between gain and transmission efficiency. This study contributes to the development of microstrip antenna technology to support next-generation wireless communication systems at mmWave frequencies. Keywords : 5G, mmWave, Microstrip Antenna, Defected Ground Structure (DGS), Bandwidth, Gain Teknologi 5G menggunakan frekuensi mmWave untuk mendukung kebutuhan komunikasi berkecepatan tinggi dan kapasitas besar. Namun, tantangan utama pada mmWave adalah terbatasnya bandwidth yang memengaruhi efisiensi transmisi. Penelitian ini mengusulkan antena mikrostrip array 1x2 dengan variasi Defected Ground Structure (DGS) untuk meningkatkan parameter kerja seperti bandwidth, gain, dan S11. Desain antena ini menggunakan substrate Rogers RO4003 dengan ketebalan 0,51 mm dan disimulasikan menggunakan perangkat lunak HFSS versi 18.0. Metodologi penelitian mencakup perancangan dan simulasi antena tanpa dan dengan variasi DGS, diikuti oleh fabrikasi dan pengukuran langsung untuk membandingkan kinerja masing-masing desain. Hasil simulasi menunjukkan bahwa antena tanpa DGS menghasilkan gain tertinggi sebesar 10,22 dBi, sedangkan antena dengan DGS berbentuk rectangular memiliki bandwidth terluas sebesar 5,63 GHz. Fabrikasi dan pengukuran langsung dilakukan untuk membuktikan bahwa desain yang diusulkan mampu meningkatkan performa antena sesuai kebutuhan. Hasil penelitian menunjukkan konsistensi antara hasil simulasi dan pengukuran, membuktikan bahwa penggunaan DGS dapat meningkatkan bandwidth secara signifikan dan memberikan keseimbangan antara gain dan efisiensi transmisi. Penelitian ini memberikan kontribusi dalam pengembangan teknologi antena mikrostrip yang mendukung komunikasi nirkabel generasi mendatang pada frekuensi mmWave.
