“…Many VAs have been reported over the last few years, including the active solution covering frequencies below 30 MHz [4] and the passive and dual-band solution operating at GSM frequencies [5]. Very recently, the authors proposed the first passive, wideband and radiation pattern (RP) reconfigurable VA [6]- [8], referred here to as the Two Season VA.…”

A wideband and radiation pattern reconfigurable vector antenna is proposed for dual-polarized and 3-D direction finding applications. Compared with the state of the art, this antenna achieves the accurate estimation of the direction of arrival of an incoming vertically-or horizontally-polarized electromagnetic field over a wider bandwidth (7:1). Measurement results are in good agreement with the simulated results obtained from full-wave electromagnetic simulations. Index Terms-wideband magnetic and electric dipoles, Vivaldi antennas, vector sensor, direction-ofarrival antenna, dual-polarized antenna, reconfigurable antenna.

“…In electromagnetic compatibility measurements [1,2], wireless sensor networks [3,4,5] and other technical areas it is necessary to measure the intensity of electrical fields with adequate accuracy. The measurement has to be performed over a sufficient frequency and voltage range, whilst the direction of the measured (incident) wave is not completely known.…”

This manuscript analyzes the omni-directivity error of an electromagnetic field (EM) probe and its dependence on frequency. The global directional characteristic of a whole EM probe consists of three independent directional characteristics of EM sensors -one for each coordinate. The shape of particular directional characteristics is frequency dependent and so is the shape of the whole EM probe's global directional characteristic. This results in systematic error induced in the measurement of EM fields. This manuscript also contains quantitative formulation of such errors caused by the shape change of directional characteristics for different types of sensors depending on frequency and their mutual arrangement.

“…It requires power sources for feeding the constitutive active components. In [8], a passive VA placed on a metallic plate is designed for operating in two separate frequencies with narrow bandwidth. To the author's knowledge, no reconfigurable, wideband and passive VA has been reported up to date.…”

Abstract-In this letter, a reconfigurable grounded wideband antenna is proposed in view of vector sensor applications. This antenna combines two orthogonal and colocated semi-circular arrays of Vivaldi antennas mounted over a metallic support. The radiation patterns of two wideband magnetic dipoles and one wideband electric dipole can be synthesized thanks to an appropriate antenna excitation. Measurement results are in good agreement with the simulated results obtained from fullwave electromagnetic simulations. The proposed antenna exhibits stable radiation patterns over a wide impedance bandwidth of 1.69:1, a high radiation efficiency and a good isolation between the antenna input ports. This antenna is a good candidate for wideband 3D direction finding using a vector sensor.Index Terms-wideband magnetic and electric dipoles, Vivaldi antennas, vector sensor, direction-ofarrival antenna, reconfigurable antenna.
