This dissertation presents a beam forming network (BFN) for phased array antenna-based on coherently radiating periodic structure (CORPS). The elements of CORPS are selected in such a way to obtain broad band characteristics, good return loss and good iso... see more

Review of the virtual prototyping and physical development of the rotary field ferrite phase shifter is presented. A description of the basic principle of operation of the rotary field ferrite phase shifter has been given along with the key aspe... see more

An analog phase shifter based on distributed MEMS transmission line (DMTL) is designed for Ku band applications. Traditional RF MEMS phase shifter comprising 6 switches has limited phase shift of 37.75° due to instability region. A new concept of stopper ... see more

Pada sistem tenaga listrik, perubahan beban tidak dapat diprediksi. Beban yang berubah secara tiba-tiba menyebabkan osilasi pada frekuensi generator. Pada sistem tenaga listrik multi area, generator bekerja secara sinkron. Osilasi frekuensi dapat menyebab... see more

This paper details the design and implementation of a modulator-less beam steering transmitter based on a revised DDS-PLL phase shifter architecture. The proposed topology targets low data rate communications for Internet-of-Things systems, and has been d... see more

The design and performance analysis of a 10 kW three-phase DC–DC LCL-type resonant converter having a built-in boost function were carried out. This high-power converter is proposed for its application in grid-interfacing a linear generator (LG)-bas... see more

Integration of renewable energy sources (RESs) and electric vehicles (EVs) to electric power grids is increasing. These RESs and EVs may introduce major problems to grid such as transmission lines congestion. Owing to the causative factors nature, congest... see more

We propose a new design of a 2x2 optical chip for switching optical modes based on silicon material. Input lights at fundamental mode of transverse electric (TE) polarization can be selected at the output by appropriately controlling a 180-degree butterfl... see more

A microstrip phased array width phase is controlled by length of line feeder is presented in this paper for application in RADAR system. The microstrip array antenna is built from dipolelike individual elemen at center frequency 650 MHz. Five different le... see more
