Improved Direction Finding Accuracy for A Limited Number of Antenna Elements with Harmonic Characteristic Analysis

A direction-finding approach for arrays with a limited number of antenna elements has been investigated. A method based on the harmonic analysis of the received signal has been proposed to solve it. The angle estimation accuracy has been improved by angle searching and peak detection. The proposed method is theoretically described and...

Circuital characteristics and radiation properties of an UWB electric-magnetic planar antenna for Ku-band applications

A planar, directive antenna with large fractional bandwidth is introduced in this paper. A detailed discussion on the proposed antenna topology and its architecture is reported. The proposed element is a combination of a patch and a loop radiator. A proper combination of the electric field radiator (patch) with a magnetic field radiator (loop...
