Abstract

Penelitian ini membahas tentang perancangan dan implementasi antena mikrostrip Compact Double Square Marge untuk aplikasi Long Term Evolution pada frekuensi kerja 2.6 GHz. Antena mikrostrip Double Square Marge patch ini dirancang dengan menambahkan coupler dengan perbedaan fasa 90? pada microstrip feeder pada antena dan menggunakan feed line sebagai metode pencatuannya.  Perancangann antena mikrostrip dilakukan secara matematis kemudian dilakukan simulasi dengan menggunakan software desain antenna secara simultan. setelah diperoleh hasil yang optimal  kemudian antena di implemenatsikan menggunakan Bahan Epoxy fiberglass ? FR 4 dengan konstanta dielektrik (?r)=4,2. Hasil pengujian antena mikrostrip Compact Double Square Marge menunjukkan adanya  tinggkat presisi yang baik pada frekuensi kerja yang direncanakan yaitu 2.6 GHz,  antena mikrostrip hasil fabrikasi menunjukan kinerja yang maksimal dengan nilai return loss -27.45; nilai gain  sebesar 7,84 dBi ; dan memiliki polarisasi ellips. Bentuk pola radiasi antena ini adalah directional. Coupler memiliki nilai return loss di bawah -25 dB dan nilai isolasi di atas -4dB.

Abstract

A complex design of electromagnetic feeding network circuit components is needed for a wireless communication network system, and expensive materials, especially for electromagnetic components at a high frequency of 5.8 GHz with dual 90-degree phase difference output using butler matrix Feeding Network for wireless communication network systems. It is novel in form and has a frequency-free, frequency-free, non-complex configuration of microstrip electromagnetic circuits, and uses inexpensive materials at a frequency of 5.8 GHz. This system is a package consisting of a 5.8 GHz microstrip antenna with a rectangular microstrip antenna array and a Butler matrix of four inputs and outputs to achieve a double 90-degree phase difference. The antenna uses a via hole for the transmission line to the network feeding system, has one band and shallow bandwidth with four ports, and has one working frequency, namely 5.58 GHz under the S criterion -10dB, and uses a via hole for the transmission line to the network feeding system, the radiation pattern is forward, the gain level is 6.83dB, and the feeding impedance is 50 Ohm. S11 -26.19 dB for the 90-degree hybrid coupler, S21 31.65 dB, S51 -26.18 dB, and S61 32.52 dB which means these are all working well, and the overall size of this structure is 80mm x 65mm with FR4 of 4.4 dielectric constant having 50 ohms.
