Telah didesain dan difabrikasi sebuah antena mikrostrip model biquad yang mampu bekerja pada frekuensi wireless yaitu 5.8 GHz yang dapat digunakan sebagai media transformasi data. Antena mikrostrip didesain pada sebuah papan PCB FR4 dengan koefisien dielektrik 4.3 dan tebal 1.6 mm, kemudian didesain dengan model biquad bentuk kubus ganda dengan ukuran panjang yang sama.Pengukuran parameter antena menggunakan Vector Network Analyzer, diperoleh nilai karakterisasi antena yaitu VSWR 1.21, Return Loss-16.25dB, Bandwidth 400 MHz. Secara umum, hasil pengukuran antena model biquad yang telah difabrikasi memiliki nilai karakterisasi VSWR ≤2 dan Return Loss dibawah -9.54 dB sehingga memenuhi syarat sebagai antena komunikasi wireless yang sesuai dengan standar industri WLAN IEEE 802.11.
