Abstract

In this paper, the design of microstrip BPF (Bandpass Filter) for WiMAX (Worldwide Interoperability for Microwave Access) application has been presented. The frequency band allocations for BWA (Broadband Wireless Access) in Indonesia are 2.3; 3.3 and 5.8 GHz. This microtrip BPF is designed using parallel coupled line in compact form and it has spesific parameter, i.e. 3.35 GHz center frequency, 400 MHz bandwidth, VSWR ≤ 2, -3 dB insertion loss and matching impedance between two port is 50 Ω. The Advanced Design System (ADS) software has been used during simulation and optimization. The simulation results show that return loss S11 and insertion loss S21 are -15.31 dB and -2.2 dB at 3.35 GHz respectively. For the design verification, the prototype of the proposed design wasfabricated and measured.The results of the fabrication approach of simulation results, which have return loss value S11and insertion loss S21 of the proposed microstrip filter are -18.20 dB and -2.91 dB at 3.35 GHz respectively. The result shows that the proposed design can be implemented forWiMAX communication system applications

Abstract

Microstrip patch antennas offer low profile and low cost fabrication advantages but limited gain and bandwidth. Some methods and techniques have been proposed and developed to improve gain of microstrip antenna, and one of them is multilayer parasitic technique. In this paper, the design and realization of rectangular patch microstrip antenna with multilayer parasitic for enhancing antenna gain that operates at frequency of 2.4 GHz is presented. The designed antenna consists of one rectangular patch as the main antenna on the first layer and the 2x2 configuration of rectangular patches on the second and third layers as the parasitic substrate. The simulation results show that the single element antenna has a gain of 3.224 dB and increases to 8.593 dB by using the parasitic multilayer antenna. The antenna design was then fabricated using an Epoxy FR4 substrate with a dielectric constant of 4.65 and a thickness of 1.6 mm. The fabricated multilayer parasitic microstrip antenna has dimension of 80 mm x 90 mm x 34.8 mm. The measurement results show that the VSWR value is 1,284 and the return loss is -18,091 dB at the center frequency of 2,442 GHz. The gain of the multilayer parasitic microstrip antenna measurement is 9.1 dB. The operation frequency range is 2.32 - 2.565 GHz at VSWR  < 2, the bandwidth of 245 MHz is achieved and unidirectional radiation patterns are obtained.

Abstract

Pada penelitian ini dilakukan perancangan dan fabrikasi modul antena dengan susunan uniform untuk sistem antena radar generasi kedua. Modul antena yang dirancang terdiri dari empat buah sub-modul yang disusun secara vertikal. Sub-modul terdiri dari susunan delapan patch berbentuk persegi yang diatur sejajar ke arah horizontal dengan metode pencatuan coaxial feed pada titik tengah sub-modul. Setiap patch antena diberi daya yang sama sehingga susunan berbentuk uniform (seragam). Antena dicetak pada bahan duroid dengan nilai εr 2,2 dengan ketebalan 1,57 mm. Hasil pengukuran antena menunjukkan bahwa antena dapat bekerja pada frekuensi 9,4 Ghz dengan nilai VSWR (Voltage Standing Wave Ratio) ≤1,5. Gain antena yang didesain sebesar 20.08 dBi dengan beamwidth horizontal 10˚ dan beamwidth vertikal 20˚.

Abstract

Cancer is one of the leading causes of death worldwide. Early detection is the best solution for cancer treatment. The UWB microwave imaging technology is one of the most promising technologies in the field of medical diagnosis, because it is non-ionizing and low cost. One of the most important elements in a microwave imaging system is an antenna. Recently, the flexible electronic is used as substrate for microstrip antenna. This paper will proposed the design of flexible antenna for breast tumor detection. The proposed antena is designed using Polyethylene Terephthalate (PET) as substrate and silver as patch. The simulation result shows flexible antenna is work at 5.8 GHz frequency with -25.27 dB value of return loss, 1.115 value of VSWR, 3.37 GHz bandwidth, 58.1% GHz impedance bandwidth and 2.68 dBi Gain. By using a flexible substrate, the antenna can follow the structure of the breast and can be placed in the breast for better breast tumor detection.

Abstract

Current technological advances and developments require the academic community to continue to innovate to build the country by improving science and technology. One area of concern for researchers is Electronics and Telecommunications. Part of the science that is currently quite indemand is the antenna. In this study discusses Stretchable Antenna Simulation Modeling for RADAR Applications, the antenna is designed using Polydimethysiloxane (PDMS) material so that theantenna can be bent and adjusted to its placement. The antenna is made with an Ultra Wideband (UWB) frequency in the frequency range of 3.1 – 10.6 Ghz with a minimum bandwidth of > 500 MHz and a return loss of < -10 dB with a VSWR of < 2, so that the antenna can detect according to radar capabilities because this frequency has wide bandwidth. When this antenna is simulated the antenna can work at a center frequency of 3.4 GHz with a bandwidth of > 500 MHz, then when the antenna is bent it does not experience a significant change in frequency, judging from the bandwidth obtained is the same but the return loss is getting lower to -43 dB but still at a frequency of 3.4 GHz.Keywords: Antena, Polydimethylsiloxane (PDMS), AgNw, Stretchable, Bending, RADAR, Ultra Wideband (UWB).

Microwave imaging system is one of the technologies that can be used to detect objects, especially in the field of medical diagnoses, such as detecting tumors in the breast. The technology used is ultrawideband (UWB) with the advantages of low cost, low power consumption, and high transmission capacity. In this study, a flexible antenna was designed at a frequency of 5.8 GHz using a polydimethylsiloxane (PDMS) substrate with a dielectric constant of 2.67 – 3.00 and a loss tangent of 0.02-0.05 for breast tumor detection applications. The antenna design process uses the CST studio suite software. The simulation results of a flexible antenna at an operating frequency of 5.8 GHz with a return loss parameter of -39.19 dB, a VSWR of 1.22, a bandwidth of 3.1 GHz in a frequency range of 4.52–7.62 GHz, the resulting radiation pattern is almost omnidirectional, and a gain of 2.26 dBi. In addition, the gain of flexible antenna with phantom breast without tumor is -23.62 dB and phantom breast with tumor is -24.85 dB at operating frequency of 5.5 GHz, which is shifted by 300 MHz from the desired frequency.
