“…The correlation between the RSS data acquired by each antenna in the RAA is proportional to λ/D, where λ is the wavelength and D is the diameter of the array [8]. However, if D is larger than λ/2, the mutual coupling between antenna elements can be ignored [9]. Also, an experimental work by Cidronali et al [10] showed that the mutual coupling was not significant for neighboring patch antennas with D ≈ 5.5 cm.…”

A relative position indicator (RPI) system with radial antenna array (RAA) is proposed and experimentally demonstrated for use in a tracking-based position estimation system (PES). Utilizing radial vectors generated by both received signal strength (RSS) and azimuth direction of each antenna element in the RAA, accurate direction and distance-to-target can be obtained simultaneously. The proposed RPI system using a radial vector sum and a simple equalization process can mitigate the gain mismatch problem, which was a serious problem in previous tracking-based PESs.

“…In this situation, the mutual couplings not only deteriorate the radiation efficiency but also increase the correlation coefficient. It is a great challenge to achieve good isolation, while the antenna element spacing is less than half-wavelength in a compact volume [1]. To solve this problem, several decoupling methods, such as defected ground structures [2], electromagnetic band gap [3], coupled resonator decoupling network [4][5][6][7], and lumped network [8], are used to improve isolation between closely packed antennas.…”

Abstract-A simple and novel WLAN antenna and a kind of neutralization line, which introduces a certain amount of signal to cancel out the unwanted mutual coupling between two antennas, are designed in this paper. The WLAN antenna working at 2.45 GHz and 5.8 GHz frequency bands is designed, fabricated and measured. The simulated and measured results show that the isolation between the two decoupled antennas can be improved to above 20 dB in both frequencies after decoupling. The lumped match network occupies less space for antennas and gains a good matching performance in the operating frequencies.

“…Many attempts have been made to reduce or to compensate for this effect. In [2][3][4], decoupling networks have been suggested based on the theory of eigenmodes of the antenna array matrix. The concept of eigenmodes based decupling networks has been applied to decouple the monopole four square array ports [5].…”

An alternative approach to port decoupling for the monopole four square array antenna is proposed. In contrast to the decoupling of the monopole four square array antenna based on eigenmodes theory, port decoupling over wider frequency band is obtained by a proper choice of parasitic elements dimensions and positions for a given array elements spacing without extending the overall area. The decoupled ports of the array may then be matched by using conventional matching circuits.
