Abstract

Taman merupakan salah satu bagian dari lingkungan hidup yang harus diberi perhatian lebih agar tanaman yang di taman dapat berkembang dengan baik. Perhatian tersebut berupa penyiraman yang rutin dan memperhatikan proteksi rumput taman dari pelanggaran pengunjung taman yang menginjak rumput sembarangan. Untuk mencegah adanya keterlambatan dalam menyiram taman dan penginjakan rumput oleh pengunjung taman akan leih baik jika pada lingkungan taman tersebut memiliki sistem perawatan taman secara otomatis. Pada penelitian ini telah dirancang sebuah antena mikrostrip menggunakan metode patch array 1x 2 untuk aplikasi perawatan taman  frekuensi 2,4 GHz. Desain antena ini memiliki dimensi antena (a) sebesar  15,5 mm dan jarak antar elemen sebesar 62,5 mm, selain itu memiliki nilai konstanta dielektrik (εr) sebesar 4.15 dan h sebesar 1.6mm. Antena ini terdiri dari antena dua elemen yang memiliki karakteristik S 1,1 sebesar -30,854 dB; VSWR sebesar 1,05; dan gain sebesar 4,69 dB. . Secara umum, antena ini telah memenuhi kinerja yang diharapkan.

Abstract

Technological developments have already penetrated low current at the time of flight of unmanned or commonly called the Unmanned Aerial Vehicle (UAV), which humans no longer need to make direct contact with the spacecraft flight to fly missions such as air monitoring in the form of realtime video. In doing missions flown required good communication and stable in order to avoid loss of signal during the communication process takes place. So we need a reliable telecommunications equipment to meet these needs, one of which is the antenna. In this final project designed three pieces of helix antenna coil 8 which works at a frequency of 5.8 GHz for applications based Autotracking antenna signal level. Systematics design includes mechanisms of designing antenna design simulation results using CST Microwave Studio Software, fabrication, measurement parameters such as return loss, VSWR, gain, Bandwitdh and Radiation Pattern, peformansi Testing and application of antenna. 1 helix antenna measurement results obtained value -17.84 dB Return Loss, VSWR 1.294, 14.53 dB Gain, Bandwitdh 300 MHz. 2 helix antenna obtained value -17.31 dB Return Loss, VSWR 1.315, 15.49 dB Gain, Bandwitdh 300 MHz, Helix Antenna 3 obtained value -18.88 dB return loss, VSWR 1.256, 15.97 dB Gain, Bandwitdh 240 MHz and shaped radiation pattern unidirectional. The test results Autotracking Antenna system based signal levels have a pretty good angle accuracy with a percentage error of the corner angle toward the target of 0.83%.
