Dual-Orthogonal Polarized Antenna for UWB-IR Technology

Abstract

Abstract-This paper presents a design of a dual-orthogonal, linear polarized antenna for the IR-UWB technology in the frequency range from 3.1 GHz to 10.6 GHz. The antenna is compact with dimensions of 40x40 mm of the radiation plane, which is orthogonal to the radiation direction. Both, the antenna and the feeding network are realized in planar technology. The radiation principle and the computed design are verified by a prototype. The input impedance matching is better than -6 dB. The measured results show a mean gain in co-polarization close to 4 dBi. The cross polarizations suppression w.r.t. the copolarization is better than 20 dB. Due to its features the antenna is suited for polarimetric ultra wideband radar and ultra wideband MIMO applications.

“…28. This type of feeding allows a separate feeding for each polarization and helps to keep the current distribution in the radiation zone symmetrical resulting in a constant phase center (of each polarization) exactly in the middle of the elliptical dipoles (two monopoles) [1]. The feeding networks themselves are placed orthogonally to the radiating element, see Fig.…”

“…Dual polarized dipole (see [26][27][28][29][30][31]) and horn antennas (see [32][33][34][35]) can already be found in the literature. Most of these antennas have the disadvantage that they have crossed feed points.…”

Principle for the Realization of Dual-Orthogonal Linearly Polarized Antennas for UWB Technique

“…The prototypes of the radiators presented in this paper are relatively bulky and are chosen only for verification purposes, due to their radiation properties. For compact realizations with stable radiation patterns over frequency and high polarization decoupling, the reader is referred to other works of the authors [14][15][16][17].…”
