| Popis: | The interference phenomena is actually appeared in all current wireless communication systems. This problem has different forms and impacts the performance of any wireless system. At the present time, a new technology, that is called fifth generation (5G), of mobile communications knocks the doors to be commercial within few days. Conventional wireless communication systems use two separate channels, one channel to transmit and another to receive. Achieving single channel full duplex (FD) is one of the key challenges for 5G implementation. Single channel FD provides the capability of sending and receiving concurrently over the same channel, along with assuring efficient utilization of the available spectrum. With this newest technology, another sort of interference will be generated which is called self–interference (SI). SI cancellation techniques represent an awesome solution for the development of next generation. These techniques have two types: passive and active cancellation. Antenna cancellation approach can be characterized as a passive cancellation. In our proposed work, antenna with two feedings is employed as a cancellation procedure. A patch antenna is simulated and tested for two resonance frequencies, 2.45GHz and 28.0GHz. Both frequencies are candidates of frequency channel proposed by ITU for the fifth generation of mobile networks. Finally, the complete design and simulation of dual polarized, with series-fed 3 by 3 patch array on 3.3GHz, is provided. |
