Abstract

This paper presents the design and development of a mini-compact Wilkinson Power Divider (WPD) operating at 9.3 GHz, with a wide bandwidth of 200 MHz, for the Man-Pack Surveillance Radar (MPSR) application. The design of the WPD was carried out using Advanced Design System (ADS) software with a microstrip feeding technique. The substrate material used in this design was Duroid Roger 5880, which has a thickness (h) of 1.575 mm, dielectric constant (εr) of 2.20, and loss tangent (tan δ) of 0.0009. A WPD was designed, developed, and measured. The simulation results obtained included return loss (S11) -37.50 dB, (S22) -26.59 dB, (S33) -26.09 dB, insertion loss (S21) -3.61 dB and (S31) - 2.55 dB, and isolation (S32) -12.89 dB. Overall, the simulation result parameters worked at a frequency of 9.3 GHz. Furthermore, when the WPD measurement produces a measured return loss of (S11) -28.69 dB, (S22) -28.5 dB, (S33) -29.95 dB, insertion loss (S21) -6.61 dB, and (S31) -7.55 dB, and isolation (S32) -21.89 dB. The dimensions resulting from the realization were 20.5 mm x 20 mm.

Abstract

MIMO (Multiple-Input Multiple-Output) Antenna Technology improves wireless network performance by allowing the use of multiple transmit and receive antennas simultaneously. MIMO antennas use antenna elements in an array, such as circular microstrip antennas, to increase signal throughput and reliability. This research simulates and develops a circular microstrip antenna into a 1×4 axe MIMO with array, operating at 2.4 GHz. The simulation shows return loss (S11) -60.913 dB, insertion loss -50.439 dB, VSWR 1.001, bandwidth 116.3 MHz, and gain 5.709 dBi. The results of fabrication and measurement achieve return loss (S11) -61.69 dB, insertion loss -43.16 dB, VSWR 1.00, bandwidth 137.2 MHz at a frequency of 2.4260 GHz. Even though there is a frequency shift of 260 MHz between the simulation and measurement results, the design of this antenna is successful according to the desired specifications.

Abstract

Microstrip antena can be the main choice in various communication applications because it has a fairly light mass and small size when compared to other types of antenas such as dipole antenas, yagi and so on. To know about the workings of radar. Use the CST Studio Suite application to simulate and analyze the difference in gain of the single antena, 1x2, 1x4, 1x8 arrays that have been made. From the results obtained from Gain with single Gain 1.73 dB, Array 1x2 Gain 2.97dB, Array 1x4 Gain 5.5 dB, Array 1x8 Gain 7.46 dBA Single Microstrip antena has small dimensions that can work at high frequencies However, this single patch Microstrip Antena has a weakness in the amount of radiant power (Gain), and a large polarization angle, to reduce the weakness of this single patch Microstrip Antena.

Abstract

ABSTRAKIndonesia merupakan negara kepulauan yang membutuhkan kemandirian teknologi radar pantai untuk keperluan pengawasan. Maka, kebutuhan akan RF amplifier yang murah merupakan suatu keharusan. Makalah ini menyajikan simulasi dan realisasi microstrip RF amplifier menggunakan RT/Duroid 5580 dan teknik matching stub pada frekuensi 9,3 GHz. Teknik ini merupakan yang efektif untuk frekuensi tinggi dan mencocokkan impedansi dengan nilai imajiner. Komponen aktif MGF2407A dipilih dengan konfigurasi DC fixed bias. Dari hasil simulasi, RF amplifier yang diusulkan memiliki gain sebesar 10,318 dB, S11 sebesar -26 dB dan S22 sebesar -28 dB dengan kompresi P1dB sebesar 11 dBm. Namun, selama pengukuran, RF amplifier memberikan redaman akibat pengaruh penyolderan, short circuit, dan electro statis discharge. Untuk parameter terukur lainnya memenuhi persyaratan standar. Hal ini menunjukkan realisasi microstrip RF amplifier untuk frekuensi tinggi memiliki tingkat keberhasilan yang rendah.Kata kunci: radar pantai, penguat daya, matching stub, mikrostrip ABSTRACTIndonesia is an archipelagic country that needs to monitor its islands. For the independence of coastal radar technology, the need for low cost RF amplifiers is a must.This paper presents simulation and realization of microstrip RF amplifier used RT/Duroid 5580 and matching stub technique worked at 9.3 GHz. This matching technique is effective for high frequency and to match the impedance with imaginer value. The active component of MGF2407A was chosen with DC fixed bias configuration. From simulation, the proposed RF amplifier has gain of 10.318 dB, S11 of -26 dB and S22 of -28 dB with P1dB compression at 11 dBm. However, during the measurement, the RF amplifier provides attenuation due to soldering, short circuit, and electro statis discharge effects. For other measured parameters met the standard requirements. This demonstrates the low success rate of realizing microstrip RF amplifiers for high frequencies.Keywords: coastal radar, power amplifier, matching stub, microstrip

Abstract

Drone, atau pesawat tak berawak, saat ini sedang mengalami masa percepatan pengembangan. Drone berpotensi membahayakan privasi dan keamanan di wilayah tertentu karena kemampuannya dalam mengambil gambar tanpa izin, mengumpulkan informasi, melakukan sabotase, dan bahkan melakukan pemboman. Penanggulangan potensial terhadap ancaman ini dapat melibatkan penerapan drone jammer atau drone blocker. Penghalang atau jammer drone. Pengacau drone rata-rata dapat mempolarisasikan sinar sejauh ribuan meter pada sudut 30 derajat. Frekuensi operasional jammer drone tidak diragukan lagi adalah 2,4 GHz, mengingat di sinilah sebagian besar drone mengirimkan data dan melakukan kontrol. Dari hasil simulasi yang dilakukan didapatkan pada frekuensi 900 MHz nilai return loss -23.48, nilai VSWR 1.14 dengan nilai gain 5.594 dBi. Pada frekuensi 1500 MHz nilai return loss - 23.91, nilai VSWR 1.13 dengan nilai gain 5.008 dBi. Pada frekuensi 2400 MHz didapatkan nilai return loss -12.24, nilai VSWR 1.64 dengan nilai gain 6.41 dBi. Setelah melakukan simulasi dilakukan fabrikasi antena kemudian dilakukan pengukuran. Pada frekuensi 900 didapatkan nilai return loss - 25.63 dengan nilai VSWR 1.1. Pada frekuensi 1500 MHz didapatkan return loss -19.4 dengan nilai VSWR 1.24. Pada frekuensi 2400 MHz didapatkan hasil return loss -19.44 dengan nilai VSWR 1.23. berdasarkan hasil simulasi dan pengukuran hasil yang didapatkan sesuai dengan spesifikasi yang ditentukan.
