Microstrip Butler matrix design and realization for 7 T MRI.
This article presents the design and realization of 8 × 8 and 16 × 16 Butler matrices for 7 T MRI systems. With the focus on low insertion loss and high amplitude/phase accuracy, the microstrip line integration technology (microwave-integrated circuit) was chosen for the realization. Laminate material of high permittivity (ε(r) = 11) and large thickness (h = 3.2 mm) is shown to allow the best t...
متن کاملA Design of Compact Ultra Wideband Coupler for Butler Matrix
A design of 3 dB compact ultra wideband (UWB) coupler for a 4 × 4 Butler Matrix, which is operating between 3 and 11 GHz frequency range, is presented in this paper. The proposed design uses multilayer technology that allows having a compact and broad bandwidth coupler. The design uses elliptically shaped broadside coupled strips and a slot created in a common ground plane of two dielectric sub...
متن کاملModified U-Slot Stacked Micro-Strip Patch Antenna for Ultra-Wideband Applications in S Band, C Band and X Band
The U-slot micro-strip patch antennas were originally developed for bandwidth broadening applications. This study presents a transmission line feed to modify the U-slot stacked rectangular micro-strip patch antenna for Ultra-Wide Band (UWB) communications. The modified antenna has a U-cut loaded with parallel slits and corner slots and is printed on a dielectric substrate of FR4 with relative p...
متن کاملUltra-Wideband Microstrip Antennas with WLAN Band-Notch Capability
The presented paper exhibits the design configuration of Microstrip Line (MS)-fed and Co-Planar Waveguide (CPW)-fed symmetrical staircase shaped, planar monopole Ultra Wideband (UWB) antennae with WLAN band rejection characteristic having sized 30x30x1.6mm. The staircase pattern in the radiating patch and the feed line’s Ushaped slot are used to achieve the UWB and notch the 5GHz WLAN band, res...
متن کاملmicrostrip flat lens with polarization diversity in x band
lenses are often used to converge electromagnetic wave namely they convert incident phase front of feed antenna to a flat phase front. together, the lens and the feed create an electrically large aperture antenna. flat lenses provide the cost and weight benefits of the reflect-arrays, while maintaining the advantages of a lens antenna. these lenses use an array of unit-cells which are excited b...
