This paper focuses on the design and development of a novel microstrip patch antenna (MPA) in ultra-high frequency (UHF) (0-1GHz) and L-band (1-2 GHz) for Traffic/Aircraft Collision Avoidance System (TCAS/ACAS) applications, with an extension to S-band (2-4 GHz) for weather radar, surface ship radar, and some communications satellites. The antenna is created in MATLAB software to fulfil the present demands of the aircraft collision avoidance system while also overcoming any constraints associated with previous approaches. It utilized FR4 substrate having dielectric constant 4.4, thickness 4 mm, and loss tangent 0.002. The simulation findings provided insight into antenna performance and other aspects. The average return loss (S11) is – 11 dB, with a voltage standing wave ratio (VSWR) near to one. The antenna attained a gain of 4.03 dBi. This antenna is ideal for TCAS/ACAS applications because to its excellent reflection coefficient, VSWR, 50 Ω impedance matching, directional radiation pattern, and high gain at operational frequencies. The suggested antenna is intended to fulfil the advanced avionics criteria for design simplicity, lightweight, and high performance. |
