“…To increase the mechanical and environmental durability of the antenna array, a cover is necessary. Previous efforts on designing an antenna element dedicated to DOA estimation are based on dipoles and composite dipoles [13], patch antenna arrays with EBG substrates [14], and Switched Parasitic Antennas (SPAs) [15].…”

Abstract-Radio Direction Finder (RDF) had been used as a part of the system in order to determine the direction of the Radio Frequency (RF) source. This research had used three different RDF stations without any mobile human operator. The direction data were collected from the each RDF station, it would be calculated using the triangle-centroid-algorithm. Therefore, the RF source position had been automatically determined. This experiment result of the RF source imaginary was compared with the real RF source at about 3.2 meters for latitude, and 3.3 meters for longitude. The results of this method and experiment are very useful for scientist and engineers in application of RF engineering.

“…In [1], a switched parasitic array (SPA) is considered by using parasitic elements (passive elements, PE) that can be shorted to ground by pin-diodes. The array is consisting of one fed element and several other parasitic elements.…”

In this paper, hemispherical DRA array mounted on or embedded in a hollow circular cylindrical ground structure and cylindrical DRA array mounted on or embedded in a pyramid ground structure, are used for direction finding systems. In the proposed arrays only one DRA element is active and the others are parasitic. The direction of the received signal will be determined by the relation between the received signal strengths at each element of the array.

“…Previous works on DOA estimation usually using isotropic antenna array and mutual coupling effect between isotropic elements is ignored [4][5][6][7][8]. There are also experimental works using directional antenna array that employ various DOA algorithms such as Bartlett [9], MUSIC [10][11][12] and Matrix Pencil [13]. To the best of our knowledge, there is no previous work that provides analysis of DOA estimation between isotropic and directional antenna array.…”

A comparison analysis between two different types of antenna arrays in direction-of-arrival (DOA) estimation is presented. This study was undertaken to point out any difference in the process of DOA estimation between isotropic and directional antenna array. To the best of our knowledge, there is no previous work that analysed the DOA estimation between these two antenna arrays. The approach taken was to estimate all predetermined angle-of-arrival (AOA) correctly by using MUSIC, a spectral-based DOA algorithm. Results obtained show that, to perform the DOA estimation, isotropic antenna array depends entirely on DOA algorithm, whereas directional antenna array required both the DOA algorithm and the position of the main beam at any instant. This work concludes that, in practical application, it is essential to consider both the performance of DOA algorithm and the beam pattern to ensure the DOA estimation is carried out correctly.
