Dalam kertas ini, tatasusunan linear 4 antena slot ikat kupu-kupu berbentuk daun dicadangkan untuk digunakan dalam jalur gelombang kuasi-milimeter. Tatasusunan antena slot direka bentuk untuk beroperasi pada jalur frekuensi 28GHz. Antena slot tali leher berbentuk daun adalah sejenis antena pelengkap diri dengan profil rendah dan kos fabrikasi yang rendah. Struktur antena yang dicadangkan menawarkan peningkatan dalam corak sinaran, keuntungan, dan jalur lebar impedans -10dB. Melalui corak sinaran kertas ini, keuntungan sebenar, dan lebar jalur impedans -10dB dinilai oleh simulasi Finite Different Time Domain (FDTD). Ciri-ciri antena dianalisis dalam julat frekuensi 27GHz hingga 29GHz. Untuk menambah baik ciri antena seperti keuntungan sebenar dan lebar jalur impedans -10dB, lapisan superstrat dielektrik dengan kebolehtelapan relatif 10.2 diletakkan di atas satah tanah tatasusunan antena slot. Tiga struktur antena diperkenalkan dan dibandingkan. Dengan dua lapisan superstrat dielektrik di atas satah tanah antena, keputusan analisis menunjukkan bahawa jalur lebar impedans -10dB menduduki julat frekuensi 27.17GHz hingga 28.39GHz. Oleh itu, lebar jalur impedans operasi ialah 1.22GHz. Keuntungan sebenar maksimum susunan antena slot dengan dua lapisan superstrat dielektrik ialah 20.49dBi dan lebar jalur keuntungan -3dB menduduki julat frekuensi 27.02GHz hingga 28.57GHz. Untuk mengesahkan keputusan analisis, prototaip tatasusunan antena slot yang direka bentuk dibuat. Ciri-ciri tatasusunan antena slot diukur dan dibandingkan dengan keputusan analisis.

Abstract: In this paper, a linear array of 4 leaf-shaped bowtie slot antennas is proposed for use in quasi-millimeter wave band. The slot antennas array is designed to operate at 28GHz frequency band. The leaf-shaped bowtie slot antenna is a type of self-complementary antenna with low profile and low cost of fabrication. The proposed antenna structure offers improvement in radiation pattern, gain, and -10dB impedance bandwidth. Through out of this paper radiation pattern, actual gain, and -10dB impedance bandwidth are evaluated by Finite Different Time Domain (FDTD) simulation. Antenna characteristics are analyzed in the frequency range of 27GHz to 29GHz. To improve antenna characteristics such as actual gain and -10dB impedance bandwidth, a dielectric superstrate layer with relative permittivity of 10.2 is placed on top of ground plane of the slot antennas array. Three antenna structures are introduced and compared. With two layers of dielectric superstrate on top of the antennas ground plane, analysis results show that -10dB impedance bandwidth occupies the frequency range of 27.17GHz to 28.39GHz. Therefore, the operational impedance bandwidth is 1.22GHz. Maximum actual gain of the slot antennas array with two dielectric superstrate layers is 20.49dBi and -3dB gain bandwidth occupies the frequency range of 27.02GHz to 28.57GHz. To validate the analysis results, prototype of the designed slot antennas array is fabricated. Characteristics of the slot antennas array are measured and compared with the analysis results.
