چکیده مقاله:
Abstract- In this article, the design of conformal antennas has been discussed using the characteristic modes (CM) method. For this purpose, the vector wave function(VWF) has been utilized to achieve a two-dimensional mapping of the conformal antenna. In designing and analyzing of cone-shaped antennas applicable for multi-input multi-output (MIMO) systems, the most important goal is to achieve a structure with the least correlation coefficient. In order to achieve this goal in these types of antennas, first an appropriate two-dimensional mapping has been selected using the vector wave functions and then its orthogonal characteristic modes have been obtained by the CPM method. In this way, a 4-port conical antenna, whose analysis had many computational problems, was designed; the results obtained from the simulation and the prototype as well as the measurement of this antenna also confirmed the low correlation coefficient (< 0.001), the gain of about 4.2 dB in a frequency of 5.5 GHz, and SWR < 1.22 in the frequency range of 4.6 to 6.6 GHz, indicating a broad bandwidth of around 32%.
