“…The front-to-back ratio is about 5 dBi. However, when comparing the patterns to that of practical dipole-triad geometry in [7], the proposed antenna can better support the ideal assumptions in [18]- [24] for polarization estimation.…”

A low-profile orthogonally linearly tripolarized antenna consisting of two thick-slot antennas and one half-mode substrate integrated waveguide (HMSIW) antenna has been investigated. The two thick-slot antennas radiate -and -directional linearly polarized waves, while the HMSIW antenna contributes to the -directional polarized wave. The low-profile geometry is achieved by utilizing the HMSIW antenna. Isolations between the three antennas measured are lower than 20 dB, which means that the proposed antenna geometry provides good diversity gain and the channel capacity can be increased by as much as three times.Index Terms-Mobile antennas, multiple-input-multiple-output (MIMO) systems, mutual coupling, polarization diversity.

“…Though, many efforts have been reported in the literature to estimate the angle of arrival or direction of arrival (DOA) [18][19][20][21][22]; only few have been considered from human vital sign detection aspect [23,24]. Table II provides the human vital sign detection (VSD) centric state-of-the-art of DoA estimation.…”

This paper reports a concurrent dualband occupancy sensor, based on Doppler principle, for monitoring of human presence in a room. The proposed sensor operates simultaneously at 2.44GHz and 5.25GHz frequency bands. The sensor prototype has been realized using own customized concurrent dualband subsystems. A measurement setup has been developed using off-the-shelf laboratory equipment and the sensor prototype. The human presence in a room has been predicted from the analysis of correlation spectrum of the signals received at individual frequency bands and from the estimation of the direction of arrival of received signals. The main advantage of the proposed sensor lies in the reduction of the false alarms, power consumption and size.

“…Although the mutual coupling effect can be reduced to some degree through EM isolation, it This work has been supported by: (1) complicates the hardware and also increases the cost [4]. To deal with this problem, the '6D distributed vector-sensor' was proposed by spreading the polarization diverse elements in a linear or a circular structure for DOA estimation [5], [6]. In [7], this mutual coupling problem was avoided by spatially displacing EMVS's six components with the vectorcross-product estimator modified accordingly.…”

A closed-form solution for direction of arrival (DOA) estimation is presented for the spatially stretched tripole (SST) by adopting a quasi-vector-cross-product (QVCP) based scheme to deal with the mutual coupling problem. After deriving the sufficient condition for the proposed method, we design and study four specific types of SSTs in particular. Simulation results show that the proposed scheme significantly outperforms the traditional tripole-based one in the presence of mutual coupling, and the Cramér-Rao bound (CRB) curves for the ideal case have also verified the superiority of our proposed method.
