Abstract

A compact microstrip patch antenna for Automatic dependence surveillance system (ADS-B) is presented. The antenna is fed by a 50Ω transmission line. T-slot is etched on the ground plane to achieve some degree of miniaturization of the design. The proposed antenna has a compact size of 82 mm × 65 mm with electrical size of 0.297λ₀ × 0.23λ₀ at 1.09 GHz. The antenna resonates at 1.09 GHz typical for ADS-B applications. The predicted gain of the ADS-B antenna is from 1dB to 5dB whereas the measured gain is about 3.10dB. It is anticipated that the proposed antenna can fulfill the ADS-B specifications. The design is validated by fabrication and measurement of the prototype. Simulated and measured results are obtained and compared.
