Fabrication And Optimization of CRLH-TL Antenna in control of Flight systems and airborne warning

In this paper, a CRLH-TL antenna is presented to cover multiple frequency bands and improve bandwidth. Antennas designed as ultra-wide bands can cover different frequency bands with small dimensions, all-directional radiation pattern and appropriate gain. Antennas designed as ultra-wide bands can cover different frequency bands with small sizes, all-directional radiation pattern and appropriate gain. Considering the basic application of antennas in Flight communication systems and control navigation, optimizing and controlling their performance in navigation is of particular importance. For this purpose, in this paper, the desired antenna structure with magnetic metamaterials has been investigated. Finally, two combination methods have been proposed to improve antenna control performance. The first method, a circuit-based model with combined CRLH structure is proposed for effective miniaturization and versatility. Then, by using incomplete terrain (via) and FSS frequency selector levels, the antenna is designed with optimal gain and bandwidth. In the proposed antenna, miniaturization is provided through metamaterial transmission line and feed by electromagnetic coupler and CRLH element. The Right- Hand part consists of 35 Micron copper metal patch and Left side of the effective transmission line of homogeneous. The FR-4 antenna bed is the characteristic impedance of 50 ohms and the frequency range is 2 to 7 GHz.removing the system design disruption by symmetrical polarization and improving the quality of bandwidth through the slotted ground. The proposed antenna is a compact microstrip antenna that improves the frequency of resonance, increases gain, bandwidth and impedance matching and ultimately an improved control system.
