Slot-line antenna array for high field parallel transmit MRI

Objective Parallel transmission is receiving more and more attention in MRI, and multi-element transmit MRI systems become commercially available. A number of different Tx/Rx antenna types have been presented for usage in parallel transmit configurations: degenerate birdcage coils, decoupled TEM or stripline coils [1,2,3]. All of these ‘traditional’ coil-types have their pro’s and con’s. We pro...

Microstrip Slot Antenna for Triple Band Application in Wireless Communication

In this paper, the design of a coaxial feed single layer rectangular microstrip patch antenna for three different wireless communication band applications is presented. The proposed antenna is designed by using substrate Roger RT/duroid 5880 having permittivity of about 2.2 and tangent loss of 0.0009. The characteristics of the substrate are designed and to evaluate the performance of modeled a...

UWB Antenna Array with Comb Taper Slot Antenna Elements

A uniformly spaced comb taper slot antenna array is proposed for directional ultra-wideband (UWB) applications. The UWB array consists of four identical comb taper slot antennas, a mutistage with four-way microstrip UWB power divider, and four identical coaxial cable lines. A maximum gain of 15.5dBi within the band is obtained when the element separation is properly selected. The uniform spacin...

Dual-Polarized Slot-Coupled Planar Antenna With Wide Bandwidth

A new dual-polarized slot-coupled microstrip patch antenna is presented, which can achieve high-isolation low crosspolarization levels, a wide bandwidth, and low backward radiation levels. The coupling slot is an H-shaped slot. For wide bandwidth and easy integration with active circuits, it uses the slot-coupled stacked microstrip patches. The theoretical analysis is based on the finite-differ...
