In order to make LEO-MSAT commercially viable, its mobile terminal must be designed as a consumer product that is low-cost, light-weight, small-in-size, and robust. This is a tall order to be fulfilled because the mobile terminal for LEO-MSAT is more complex than its counterparts for GEO-MSAT although the former has a lower power rating. Comparing with a DBS antenna, a MSAT antenna must be equipped with a steerable main-beam for tracking the satellite position, preferably it is an automatic tracking system. Moreover, the antenna must be low-cost, high-gain, high-efficiency, small-in-size, and preferable low-profile. To this end, an innovative antenna that satisfies most of the aforementioned requirements has been conceived. The innovative antenna is an array comprising two to three antennas. Each antenna itself comprises a coaxial transmission line protruded from a ground plane. In this paper, an accurate analytical technique is developed for studying and designing the element of the novel LEO-MSAT antenna array, the multi-slot coaxial line antenna. The calculated and experimental radiation patterns show that the technique is successful.","PeriodicalId":391546,"journal":{"name":"IEEE Antennas and Propagation Society International Symposium. 1999 Digest.

SAM is known to be one of the most powerful techniques of electromagnetic sounding data processing. The advantages of SAM include the universality of its algorithm and the high resolution capability that it can produce. Images of non-dissipative and low-absorbing media can be efficiently treated with this technique. The applicability of SAM to the processing of data collected from media having non-negligible conductivity is rather limited. It is necessary to note, that such a conductivity is relevant in all moist soils. Thus, SAM needs a modification that will permit to take into account a distortion of the sounding impulse in a conducting medium. A modification of SAM that enables one to take into account the shape of the radiated impulse at a given depth is discussed. Also, two methods of estimation of this shape are proposed: 1. Rough estimation of the transfer function of the medium using its material parameters; 2. Shape pulse estimation using the FDTD technique.","PeriodicalId":391546,"journal":{"name":"IEEE Antennas and Propagation Society International Symposium. 1999 Digest.
