We present analytical expressions for the evaluation of the antenna efficiency loss due to the gravity distortion on large reflector antennas from 6 to 35 m diameter at X and Ka bands with a lack of usual complexity. These analytical expressions can

The problem of 3D near-field source localization using virtual arrays is addressed. The proposed method is based on a spherical wave steering vector whose performance of 2D direction-of-arrival and range estimation is evaluated via MUSIC-based algori

Adaptive-type smart antennas do not usually operate on the deployed universal mobile telecommunication system (UMTS) scenarios, although UTRA (UMTS terrestrial radio access) foresees their operation and they would improve capacity especially in mixed
