PranaWijaya, Oky (2016) Simulasi Dan Pengujian Antena Mikrostrip Array Untuk Mengetahui Pengaruh Variabel Gain Terhadap Efisiensi Daya Antena. Sarjana thesis, Universitas Brawijaya.
Abstract
Efisiensi daya dari antena bertujuan untuk mengurangi kerugian daya (losses). Rugi-rugi yang rendah membuat kinerja antena optimal dalam memancarkan dan menerima gelombang. Jangkauan (range) antena juga dapat dioptimalkan karena daya yang lebih besar dapat dipancarkan, sehingga mengurangi kebutuhan perangkat transceiver yang mengkonsumsi banyak daya. Penulis menggunakan antena mikrostrip dengan jumlah patch array yang berbeda-beda dibuat untuk menemukan nilai gain yang berbeda. Hasil dari simulasi antena didapatkan nilai gain antena berturut-turut 2.55 dBi, 3.08 dBi, 4.32 dBi, 5.05 dBi dan 6.21 dBi. Sedangkan untuk efisiensi antena didapatkan 0.98272323, 0.98395813, 0.9851897, 0.98815117, dan 0.99053464. Hasil dari pengukuran antena yang telah difabrikasi didapatkan nilai gain berturut-turut -2.44 dBi, -2.05 dBi, -0.77 dBi, -0.63 dBi dan 2.00 dBi. Dari pengukuran daya teradiasi antena didapatkan nilai efisiensi beturut-turut 0.3937, 0.4908, 0.5529, 0.57, dan 0.6262. Hasil penelitian ini diketahui bahwa semakin besar nilai gain dari antena, semakin tinggi efisiensi dayanya.
English Abstract
The power efficiency of the antenna is aimed to reducing power loss (losses). Low Losses making optimal antenna performance in transmitting and receiving waves. Range of the antenna can also be optimized because of greater power can be transmitted, thus reducing the need transceiver devices that consume a lot of power. The author uses a microstrip antenna array with a number of patches to different made to find a different gain value. The results of the simulation of antenna gain antenna values obtained successively dBi 2.55, 3.08 dBi, 4.32 dBi, 5.05 dBi and 6.21 dBi. As for the antenna efficiency is obtained 0.98272323, 0.98395813, 0.9851897, 0.98815117 and 0.99053464. The results of the measurements obtain fabricated antenna consecutive obtained gain value -2.44 dBi, -2.05 dBi, -0.77 dBi, -0.63 dBi and 2.00 dBi. From measurements of the radiated power antenna efficiency values obtained third consecutive 0.3937, 0.4908, 0.5529, 0.57, and 0.6262. The results of this research concluded that the greater the value of the gain of the antenna, the higher the efficiency of the power.
