Abstract

Some areas, including those within a city, struggle with good internet speed due to network congestion especially band 3 (1.8GHz) and band 7 (2.6GHz) as they are widely used LTE bands in Malaysia. Moreover, a high gain and directional dual-band antenna is expected to overcome this problem while focusing in Yagi Uda design. However, a dual-band antenna using a conventional Yagi-Uda structure requires two sets of antennas, making it bulky and harder to maintain. Therefore, this project proposed the design and analysis of dual-band Quasi-Yagi antenna for 4G LTE band in 1.8GHz and 2.6GHz using FR4 as a substrate, to resolve this issue. Due to a lightweight microstrip antenna’s properties and a low-cost antenna, it is perfect for this purpose. The antenna is first designed and simulated in CST software to achieve the desired resonance frequency followed by lab test and field test to validate the antenna’s functionality. Result shows the proposed antenna has return loss below -10 dB, voltage standing wave ratio (VSWR) below than 2, gain of 4.625 dB and 5.4 dB, and directional radiation pattern at E-plane for 1.8 GHz and 2.6 GHz respectively. From the field test, it is proven that the proposed antenna able to improve overall network performance in term of speed and strength.
