Abstract

The development of a THz system often requires a device that is used to radiate or detect THz waves. One way to fulfill this requirement is to use an antenna. Therefore, we need to consider the radiation characteristics of an antenna working in the THz region. In this paper, we present simulation study of two dipole antennas, i.e. a planar strip dipole antenna and a slot dipole antenna. The simulation results show that a planar strip dipole antenna has a better radiation efficiency (more than 95%) compared to the slot dipole. It also shows that an efficiency of more than 98% can be achieved when using silicon dielectric substrate. Furthermore, a return loss characteristic of 38,752 dB can be achieved by using a silicon dielectric substrate and a metal layer of Au for the planar slot dipole antenna.

Bahasa Abstract

Ciri-Ciri Radiasi Antena Dwikutub Bilah Planar dan Antena Dwikutub Celah untuk Aplikasi THz. Pengembangan sistem THz seringkali harus didukung oleh alat khusus yang digunakan untuk memancarkan atau mendeteksi gelombang THz. Salah satu cara untuk memenuhi fungsi ini adalah dengan menggunakan antena. Oleh karena itu, ciri-ciri radiasi antena yang berfungsi di zona THz harus diperhatikan. Makalah ini menyajikan hasil kajian simulasi dari dua jenis antena dwikutub, yaitu antena dwikutub bilah planar dan antena dwikutub celah. Hasil simulasi menunjukkan bahwa antena dwikutub bilah planar memiliki tingkat efisiensi radiasi yang lebih tinggi (lebih dari 95%) daripada antena dwikutub celah. Ditunjukkan pula bahwa tingkat efisiensi sebesar lebih dari 98% dapat tercapai dengan penggunaan substrat dielektrik silikon. Selain itu, karakteristik kembali rugi sebesar 38.752 dB dapat tercapai dengan penggunaan substrat dielektrik silikon dan lapisan logam Au pada antena dwikutub celah planar.
