Antenna for nonterrestrial mobile telecommunication system
First Claim
1. A cellular mobile telecommunication system for providing radio communication with non-terrestrial cellular mobile telecommunication stations using radio frequencies allocated for ground based cellular mobile telecommunication stations, comprising:
- at least one radio transmitter for generating signals for producing at least one telecommunication cell, each having three-dimensional extent and serving non-terrestrial cellular mobile telecommunication stations with communication signals generated by said at least one transmitter being at wavelengths allocated for ground based cellular mobile telecommunication stations; and
at least one radio receiver for receiving communication signals generated by cellular mobile telecommunication stations extant in said at least one telecommunication cell;
at least one antenna mast; and
non-terrestrial antenna means, mounted on said at least one antenna mast, having an antenna characteristic pattern which points skyward, and connected to said at least one transmitter for broadcasting said signals generated by said at least one transmitter to produce said at least one telecommunication cell.

Abstract
The multidimensional cellular mobile telecommunication system extends the usage of existing cellular mobile telecommunication radio frequencies allocated for ground-based communications to non-terrestrial mobile subscriber stations by adding an overlay of non-terrestrial cells of predetermined geometry and locus in space to the existing ground-based cellular cell site network. The polarization of the signals produced by the non-terrestrial antenna elements is a polarization that is different than and preferably substantially orthogonal to the polarization of the cellular radio signals produced by the ground-based antennas, such as a horizontal polarization, to thereby minimize the possibility of interference with the vertically polarized ground-based radio signals. Furthermore, the control signals exchanged between the non-terrestrial mobile subscriber stations and the non-terrestrial cell site controller are architected to avoid the possibility of interference with ground-based cell site transmitter-receiver pairs. In particular, the control channels used for the non-terrestrial mobile subscriber stations are selected such that the control signals transmitted in these channels are unrecognizable to the ground-based mobile subscriber stations and cell site transmitter-receiver pairs, so that even if broadcasts from a non-terrestrial mobile subscriber station reach a ground-based mobile subscriber station or cell site receiver, they cannot be interpreted and are rejected out of hand.
