This paper presents the development and construction of a low-cost passive phase conjugating array (PCA) antenna aiming the mitigation of multipath phenomena at 6GHz. The implementation of the proposed array was performedon woven fiber glass substrate using both discrete and integrated circuits.
Measurement results, obtained inside an anechoic chamber, from a 16-element PCA antenna under multipath conditions are used to validate its feasibility for vehicular applications where beam steering is required. Tests performed in the chamber yield to an average gain of 9dB across a 120 angular range and peak gains of 32dB. The relative good performance of the proposed PCA topology clearly demonstrates its benefit in mitigating multipath fading and, consequently, fade margin reduction.
