Compact Four-Element Phased Antenna Array for 5G Applications

Phased array antenna using MEMS phase shifter

This article presents a phased array antenna employing MEMS phase shifter. The proposed phased array antenna consists of eight square patch antennas operating at 10.4 GHz with a bandwidth of 400 MHz. Feed line for each patch passes through a MEMS phase shifter realized by a series of bridges above the transmission line. The distance between the bridge and the transmission line underneath it is ...

A New Compact Ultra-wideband Linear Antenna Array for Target Detection Applications

This paper presents a low-cost compact planar microstrip-fed monopole antenna and its four-element array design for ultra-wideband (UWB) wireless communication and target detection applications, respectively, operating in the frequency span of 3 GHz to 11 GHz. A prototype was fabricated and then measured based on optimal parameters. The results of reflection coefficient (S11) and radiation patt...

Flexible Four Element Phased Array Coil for Supine Breast MRI

INTRODUCTION Dynamic contrast enhanced breast MRI shows a high sensitivity for breast cancer [1]. To avoid respiratory motion artifacts, breast MR images are currently acquired with the patient in a prone position. Supine unilateral breast MRI has several applications including scanning of patients with known claustrophobic sensations, as an aid to breastconserving surgeries and guidance of bre...

Sparse Phased Array Antenna Architectures for 3D-SAR Applications

We discuss sparse phased array antenna architectures by the use of multiple transmit antenna positions in order to reduce the number of needed receiver channels. We also present a compact array architecture where the synthetic array antenna size is doubled without increasing the physical array size significantly. We compare sparse arrays of 10, 20, 40 and 80 receiver positions respectively (tog...
