Small Size Ka-band Distributed Mems Phase Shifters Using Inductors
MEMS phase shifter has been developed using inductors. The design consists of a CPW line capacitively and inductively loaded by the periodic set of inductors and electrostatic force actuated MEMS switches as capacitors. By applying a single bias voltage on the line, the characteristic impedance can be changed, which in turn changes the phase velocity of the line and creates a true time delay ph...
متن کاملMiniaturized Phase-Shifters for Ka-Band Phased Array Antennas
Realizing robust and stable two-way links between the mobile users and the satellite is an extremely challenging RF/Microwave engineering problem. Low cost and low pro le phased array is considered as the best solution for this problem. High performance low cost and miniaturized variable phase shifter is a key enabling technology for such complex smart phased array antenna system. This thesis a...
متن کاملCompact Distributed Phase Shifters at X-Band Using BST
A new type of distributed analog phase shifter is presented that utilizes the coplanar strip transmission line topology. This transmission line has several benefits for phase shifter design, resulting in decreased physical dimensions and potentially lower losses. A prototype was constructed using thin-film barium strontium titante (BST) varactor technology. The design achieved a 49◦/dB figure o...
متن کاملVery Small Size ka Band 6 Bit DMTL Phase Shifter Based on Combination of Capacitor and Resonator Type Methods
Abstract- Design and simulation of a very small size 6-bit DMTL phase shifter is presented. The idea is based on using both capacitor and resonator type methods simultaneously in a phase shifter. The capacitor section creates less significant bits. The bits in this section start from the least significant bit, with 5.625-degree steps. The resonator section creates the bits with 90-degree steps....
متن کاملEffects of Resonance-Based Phase Shifters on Ka-Band Phased Array Antenna Performance for Satellite Communications
Phase shifters are the key components of phased array systems which provide a low-profile solution for Ka-band satellite communications. In the transmitting mode, it is crucial for the phased array antenna system to meet the standard radiation masks, and any imperfections of phase shifters can yield into radiation mask violation. In this paper, we present the analytical approach to model the no...
