Untuk mendukung komunikasi antar jaringan WLAN diperlukan antena yang dapat memperkuat daya tangkap sinyal kepada sinyal Wifi, maka dirancang antena mikrostrip Array patch segitiga dan lingkaran. Dengan menambahkan jumlah elemen pada antena yang dapat memperbesar Gain. Spesifikasi antena mikrostrip memiliki panjang sisi segitiga = 39 mm, jari – jari lingkaran = 16 mm, menggunakan teknik pencatuan mikrostrip feedline, menggunakan substrat Epoxy FR-4 dengan ketebalan substrat 1,6 mm dan permitivitas relative 4,4.Untuk perancangan dilakukan simulasi dengan menggunakan software ANSYS HFSS. Hasil simulasi dari antena mikrostrip Array 2 X 4 patch segitiga dan lingkaran yang didapatkan yaitu pada frekuensi kerja 2400 MHz, Return Loss 16,5397dB, VSWR 1,35, bandwidth 134,8 MHz, Gain 6,1234 dB, dan pola radiasi unidireksional.Hasil pengukuran antena mikrostrip array 2 X 4 patch segitiga dan lingkaran didapatkan hasil untuk frekuensi tengah 2400 MHz , return loss 16,020 dB , bandwidth 145 MHz, VSWR 1,375, gain 5,2 dBi dan pola radiasi unidireksional.

To support communication between WLAN networks, an antenna is needed that can strengthen the signal capture power of the Wifi signal, so a triangular and circular patch array microstrip antenna is designed. By increasing the number of elements on the antenna can increase the Gain. The microstrip antenna specification has a triangular side length = 39 mm, circle radius = 16 mm, using the feedline microstrip feeding technique, using an Epoxy FR-4 substrate with a substrate thickness of 1.6 mm and a relative permittivity of 4.4. For the design, a simulation is carried out with using ANSYS HFSS software. The simulation results of the microstrip Array 2 X 4 patch triangular and circular antenna obtained are at a working frequency of 2400 MHz, Return Loss 16.5397dB, VSWR 1.35, bandwidth 134.8 MHz, Gain 6.1234 dB, and unidirectional radiation pattern. The measurement results of the 2 X 4 patch triangular and circular patch microstrip antenna were obtained for the center frequency of 2400 MHz, return loss of 16.020 dB, bandwidth of 145 MHz, VSWR 1.375, gain of 5.2 dBi and unidirectional radiation pattern.
