The answer lies in the beamspace domain representation of parasitic antenna arrays.
This paper explores the beamspace domain representation of parasitic antenna arrays and elaborates on the aerial degrees of freedom provided by these arrays.
Both baluns have sharp peaks at 4.4 and 4.9 GHz in their transfer characteristics due to the parasitic antenna
Within the proposed synthesis methodology, the array configuration and the relevant parameters [[bar.x].sub.n], [[bar.A].sub.n], [[alpha].sub.n] (n = 1, 2, ..., [N.sub.a]) are optimized by means of a suitable metaheuristic algorithm in combination with the multiport network modeling detailed in Section 3 in order to compensate for the detrimental effects of parasitic antenna
Therefore, if we were to take full advantage of the parasitic array capabilities, the loading circuit controlling the parasitic antenna
loads should be able to provide a complex loading, which can be realized with a novel active circuit design.
