Researches on microstrip antennas which emphasize on its performance and miniaturization have been carried out extensively. The selection of dielectric material could sometimes achieve the desired antenna performance for some application. Therefore, the dielectric material usage is still one of important factors in the design and implementation of microstrip antennas. This paper proposes a 1×2 linear array triangular patch antenna design for mobile communication application. The array antenna which is designed on FR4 epoxy dielectric substrate with the thickness of 1.6 mm and relative permittivity 4.3 is configured with several feeding line systems. Some antenna parameters such as operating frequency, reflection coefficient, bandwidth, and gain are used to evaluate the performance of array antenna. From the characterization, the proposed array antenna has operating frequency of 2.364 GHz, reflection coefficient of −35.753 dB, working bandwidth of 83 MHz, and gain of 3.375 dB.","PeriodicalId":220618,"journal":{"name":"2019 IEEE 5th International Conference on Wireless and Telematics (ICWT)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130006145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition to these benefits, risk factors in the form of accidents are generally followed by disconnection of communication between aircraft and air traffic controllers. In that case, we could search an emergency locator transmitter to find the location where the accident occurred. However, such signal is vulnerable to fire and shock caused by an aircraft accident. This paper proposes a prototype of global positioning system (GPS) transceiver for quadcopter based emergency locator beacon. A quadcopter equipped with a GPS transmitter, accelerometer sensor, and ATmega128 microcontroller could be put in a special place on the aircraft. The quadcopter will work or be activated if the accelerometer sensor detects an impact or sudden drop in height. While, a GPS receiver equipped with a Visual Basic 6 based desktop application was developed to detect the location of quadcopter. Experimental results show that the GPS receiver managed to detect the location of the quadcopter and convert GPS data into satellite images in real time through an application developed on the GPS receiver.","PeriodicalId":220618,"journal":{"name":"2019 IEEE 5th International Conference on Wireless and Telematics (ICWT)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121895956","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
