Abstract

This paper aims to investigate and design a Yagi disc antenna with a variable number of director elements for Band 3 in fourth-generation long term evolution (4G LTE) mobile applications. The array technique was introduced by increasing the number of director elements to achieve superior results and better performance, such as higher gain and lower return loss. Initially, the simulated results of return loss and gain with one director element were -19.02 dB and 8.51 dBi, respectively. Then, by increasing the number of directors to three and five elements, the antenna’s performance improved significantly from -32.44 to -42.68 dB for return loss and from 8.51 to 11.17 dBi for gain, respectively. The simulated circular Yagi disc antenna provided a response in the range of 1.78 to 1.82 GHz. Therefore, a model was fabricated and tested to validate the antenna design. The measured results matched well with the simulated ones. By increasing the number of director elements, the measurement results of gain and return loss at a frequency of 1.8 GHz also showed improvement from 7.70 to 11.09 dBi and from -27.31 to -32.91 dB, respectively. Meanwhile, the measured antenna provided a wider bandwidth in the range of 1.72-1.82 GHz.

Abstract

LTE menyediakan kecepatan data hingga 100 Mbps pada downlink dan hingga 50 Mbps pada uplink. Kecamatan Kelayang merupakan salah satu tempat yang memiliki banyak pengguna LTE, karena lokasinya yang padat penduduk, khususnya di kawasan Peranap dan Bongkal Malang. Berdasarkan hasil drive test, ditemukanlah permasalahan yaitu mutu throughput, RSRP serta SINR yang kondisinya sangat kurang baik. Oleh karena itu, dilakukan simulasi optimasi menggunakan metode electrical tilt. Hasil throughput pada SITE_PERANAP_4G dan SITE_BONGKAL_MALANG 4G setelah optimasi meningkat menjadi 49.000 kbps. Hasil parameter RSRP pada SITE_PERANAP_4G dan SITE_BONGKAL_MALANG 4G setelah optimasi meningkat menjadi >= -70 dBm. Hasil parameter SINR pada SITE_PERANAP_4G dari nilai -20 dB meningkat menjadi 30 dB setelah optimasi. Sementara itu, pada SITE_BONGKAL_MALANG 4G dari nilai -20 dB meningkat menjadi 20 dB setelah optimasi.

Abstract

The implementation of 4G LTE in Indonesia still faces numerous challenges, particularly in terms of coverage areas that are less than optimal, causing many areas to be classified as bad spots. One of them is Koto Baru Payobasung area, Payakumbuh. Network optimization is one method for overcoming this problem. In this study, we will use optimization techniques such as Automatic Cell Planning (ACP) and Carrier Aggregation (CA) with RSRP, SINR, and Throughput parameters. Through existing simulations, the results of the initial research revealed that two of the three parameters, namely RSRP and Throughput, were classified as very bad conditions. Based on the results of optimization using the ACP technique, it was discovered that there was an increase in the RSRP value of = -103 dBm, SINR of = 2 dB, and Throughput = 15 mbps. The RSRP value for the CA technique is -90 dBm, the SINR is 7 dB, and the throughput is 50 mbps. Because of the value of the optimization parameter results, the CA technique is more effective than the ACP technique in these two optimization techniques
