The Antenna Design of Electrical Engineering Lecturer Acknowledged by International Journal

Radio Frequency Identification (RFID) is a technology to identify and control data remotely using radio wave transmission. RFID uses a transponders or RFID tags to store and retrieve data remotely. RFID tag is similar as the use of barcode attached to an object that stores the identification of object data. The antenna is one of the important components in RFID tag which used to sent and capture signals which transmitted by antenna using radio signal.
Lecturer at Electrical Engineering, Rudy Yuwono ST., M.Sc, designed a microstrip antenna for RFID tag applications. Microstrip antenna designed by the man from Tulungagung have a circular shape/dimension. To obtain a wide operating frequency (ultra wideband), the antenna is designed with egg slot on the ground plane and using a feed line for transmission method. By applying the technology of Ultra Wideband (UWB) which can operate at a frequency of 2.4 GHz RFID (RFID UWB), the distance needed to identify the data or objects can be farther than using narrowband RFID.
Fabrication of the microstrip antennas is using Phenolic White Paper – FR2 materials with dielectric constant (εr)= 4,5. From the simulation results, the antenna design of lecturers who had graduate from Kassel University has a bandwidth of 2679 MHz with 2128-4807 MHz operating frequency and small relatively small gain of -17.398 dBi. The addition of rectangular stub in the ground plane cause shift the operating frequency range of 1166-3475 MHz and narrowing of bandwidth into 1815 MHz but increasing the value of the gain at a frequency of 2.4 GHz to -2.733 dBi.
With the relatively small, flexible, and good performance form of antenna; microstrip circular patch antenna is suitable for UWB applications of RFID tags.
The antenna design of lecturer of radar and navigation courses have been organized in the form of a journal titled “Design of Circular Patch Microstrip Antenna with Egg Slot for 2.4 GHz Ultra-Wideband Radio Frequency Identification (UWB RFID) Tag Applications.” The journal has been published in the international journal of Applied Mechanics and Materials Vols. 513-517 (2014) pp. 3414-3418 edition in February 2014 and published by Trans Tech Publications publisher, Kreuzstr. 10, CH-8635 Zurich-Dürnten Switzerland with ISSN number 1662-7482.
