Frequency reconfiguration of a dual-band phased array antenna with variable-impedance matching

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...

Recent developments in reconfigurable and multiband antenna technology

A comparative analysis of various reconfigurable andmultiband antenna concepts is presented. In order to satisfy the requirements for the advanced systems used in modern wireless and radar applications, different multiband and reconfigurable antennas have been proposed and investigated in the past years. In this paper, these design concepts have...
