Quartz Crystal Microbalance (QCM) merupakan salah satu jenis resonator kuarsa yang memiliki membran sensitif terhadap gas. Pada sistem identifikasi gas menggunakan QCM, perubahan frekuensi dari sensor ini begitu cepat, sehingga untuk mendapatkan perubaha... see more

The mangosteen fruit has a characteristic thick skin, so it is difficult to know the condition of the flesh. Farmer can only know damage to the fruit flesh after the fruit skin had opened. Detection of the quality of the mangosteen flesh can be detected u... see more

Substrate integrated waveguide (SIW) is a technique to implement waveguide into microstrip material that can be applied to filter, antenna, mixer, coupler, and so on. Implementation of SIW to filter can overcome the problem of size reduction and high... see more

Ceramics based on magnesium titanate (MgTiO3) are dielectric materials that have the potential to be used in telecommunications systems at microwave frequencies, such as filters, antennas, and signal generators. This study aims to characterize the resonan... see more

The mangosteen fruit has a characteristic thick skin, so it is difficult to know the condition of the flesh. Farmer can only know damage to the fruit flesh after the fruit skin had opened. Detection of the quality of the mangosteen flesh can be detected u... see more

This research proposes a 5.8 GHz circular polarization double square edge antenna with a bandpass filter that used a method stepped impedance resonator (BPF-SIR) structure for designing a compact integrated antenna with the filter. the double layer electr... see more

In the present work, the conventional chemical oxygen iodine laser (COIL) source has been technologically upgraded and successfully tested after implementation of decoupling interface between laser cavity and resonator. In the technique, anti-reflection c... see more

A compact wide band reconfigurable bandpass filter (BPF) which utilises a hemi-circular flower shaped multimode resonator (MMR) is presented. The proposed MMR provides three resonant modes which fall within the broad frequency spectra. Among these, two mo... see more

Radar atau Radio Detection and Ranging merupakan salah satu produk telekomunikasi yang berperan sangat penting pada masa kini. Kegunaan radar sangat beragam, contohnya radar dapat digunakan dalam memperkirakan cuaca. Radar cuaca memiliki kemampuan untuk m... see more
