Global communication coverage is only possible by integrating Non-Terrestrial Networks (NTN) with the currently available terrestrial networks, forming a 3-D unified network. While conventional satellite access has been enabled with fixed dish-type of antennas, the proliferation of LowEarth Orbit (LEO) claim for steeri...
A new compact automotive multi-antenna module is presented for 5G multiple-input multiple-output applications, as well as Satellite Digital Audio Radio Systems (SDARS) and Global Navigation Satellite System (GNSS) applications in the L1 and L5 bands. The new design consists of two broadband monopole Palm tree antenna...
Antenna arrays are widely used as the antennas of modern radio systems today. The ability to control the Radiation Pattern (RP) of such antennas underlies the operating principle of the Adaptive Antenna Arrays (AAA). These arrays suppress the signals from the interference sources whose frequency bands overlap with the...
This paper presents the design, fabrication, andevaluation of a Very High Frequency (VHF) Eggbeaterantenna operating at 145 MHz for Low Earth Orbit (LEO)satellite communication. The antenna consists of twoperpendicular loop elements fed with a 90° phase shift toachieve right-hand circular polarization (RHCP) andnear-om...
This paper presents a series-fed 2 × 4 antenna array operating at multiple bands, namely, GNSS (Global Navigation Satellite System) L1 and L2 bands, NavIC (Navigation with Indian Constellation) S band, and 5G n78 band. The novel series-fed antenna is designed with non-symmetrical radiating elements connected in series...
