Penggunaan frekuensi 1090 MHz pada sistem 1090 Extended Squitter (1090ES) menuntut antena dengan pencocokan impedansi yang baik agar energi dapat disalurkan secara efektif. Antena mikrostrip dipilih karena memiliki profil tipis, ringan, dan ringkas, sedangkan model meander line digunakan untuk memperpanjang lintasan arus dalam area fisik yang terbatas. Penelitian ini bertujuan menganalisis parameter antena mikrostrip dengan model meander line pada frekuensi 1090 MHz melalui perancangan dan simulasi elektromagnetik menggunakan CST Studio Suite. Parameter yang dianalisis meliputi return loss, VSWR, impedansi, gain, dan bandwidth. Hasil optimasi menunjukkan bahwa model antena mampu beresonansi pada 1090 MHz dengan return loss -24,14 dB, VSWR 1,13, magnitudo impedansi 51,35 Ω, gain 2,38 dBi, dan bandwidth 346,73 MHz. Hasil tersebut menunjukkan bahwa rancangan memenuhi kriteria parameter utama pada tahap simulasi dan dapat menjadi dasar untuk pengembangan antena ADS-B pada penelitian selanjutnya.
