摘要：In this paper, the concentric ring antenna array is developed to improve the communications link in wireless sensor networks. This technique is applied to the new Stratospheric Aerial Platform (SP) infrastructure for Sensor Networks. An adaptive current feeding for the array is applied. The simulation results show the possibility of communications between the SP sink station and sensor nodes locate d on the ground. The proposed ring array is optimized using a modified Dolph-Chebyshev feeding and comparison with conventional antenna models in literature shows the improvement in communications performance in terms of bit energy to noise power spectral density ratio by considerable.
