Analysis high gain waveguide slot antenna 2.3 GHz for Long Term Evolution-Time Division Duplex (LTE-TDD)

Abstract

Abstract Waveguide slot antenna has many benefits in term of high gain, simple design and stable performance that can be applied to telecommunications systems. This paper will discuss about the design and analysis of waveguide slot antenna for LTE (Long Term Evolution) at a frequency of 2.3 to 2.4 GHz. The results obtained will be used for reference whether the antenna can be used for LTE-TDD frequencies. This research was conducted in two steps. The first step involved simulation of antenna design and optimization using 3D Electromagnetic Simulator software. Data simulation results showed that the working frequency of the antenna between 2.30 to. While in the second step, fabrication and measurement were carried out using a spectrum analyser and network analyser. The results obtained from measurements show that the antenna has a frequency between 2.28 to 2.41 GHz with bandwidth 130 MHz. The antenna has a directional radiation pattern with a gain at a frequency of 2.3 MHz of 15.68 dBi. From the simulation results and measurement, it can be concluded that the design of these antennas can be used for LTE-TDD applications.
