Radiation Characteristics of Chebyshev Function-Based Power Weighted Linear Array Antennas Influenced by Elements Configuration

The radiation characteristics of Chebyshev function-based power weighted linear array antennas influenced by elements configuration are investigated in terms of width of main lobe (WML) and sidelobe level (SLL). The investigation is also performed using a theoretical approach focused on synthesizing process. The use of Chebyshev function as weighting coefficient for linear array antennas with number of elements less than 10 shows that the variation of array-elements-number (N) with a constant inter-elements-spacing (d) can improve WML and provide notable impacts to SLL. While the variation of inter-elements-spacing (d) with a constant array-elements-number (N) yields to the WML improvement without significant effect on SLL. The theoretical approach is then validated by the experimentation with the error rate in SLL and WML of 1.68% and 3 %, respectively.
