A Simultaneous Dual Channel Communication Concept over 4D Arrays in Satellite Networks

In this study, a dual channel transmission concept over a single array with different frequencies and angle of arrivals without time division is presented. A time modulation scheme is applied to an ordinary linear array and the difference between main and fundamental radiation which can be steered independently with different frequencies is exploited in order to achieve a dual channel. By this way, both the so-called wasted power may be used in communication, and an independently steerable dual beam array may be constructed which may be utilized especially in multi-terminal communication infrastructures such as satellite networks. Since it is one of the fundamental communication techniques that the advanced ones are constructed on, a dual channel FM receiver structure is presented as an illustrative example to show the proposed concept is utilizable.
