A Novel Multi-Dimensional Spectrum Estimation Technique using Antenna Array Displacement

A Novel DOA Estimation Algorithm Using Array Rotation Technique

The performance of traditional direction of arrival (DOA) estimation algorithm based on uniform circular array (UCA) is constrained by the array aperture. Furthermore, the array requires more antenna elements than targets, which will increase the size and weight of the device and cause higher energy loss. In order to solve these issues, a novel low energy algorithm utilizing array base-line rot...

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 ...

Novel Circularly Polarized Substrate Integrated Waveguide Slot Antenna By Using A Polarizer Technique

circularly-polarized antenna is built based on new SIW(substrate integrated waveguide)structure which contains cavity-backed resonator and a conventional polarized ring with twosquare slits in inner and outer ring that differ 90° at position and is proposed for right-handedcircular polarization (RHCP) and fabricated in two separate layers. A broadband impedancebandwidth of 13.9% and a RHCP axia...

Direction of Arrival Estimation using a Sparse Linear Antenna Array

1057 Abstract—This paper presents the use of Inverse Free Krylov Subspace Algorithm (IFKSA) with Estimation of Signal Parameter via Rotational Invariance Technique (ESPRIT), for Direction-of-Arrival (DOA) estimation using a Sparse Linear Array (SLA) of antenna elements. The use of SLA reduces the hardware requirements and the production cost. The SLA generates the sparse data, the pure signal s...
