This is commonly used on its own and is also integrated into many other prototypes of the RF antenna, where it is the guiding factor for the antenna. An effort has been made in this project to study the latest half wave dipole antenna for LTE Applications. The dipole antenna, which is nearly one-half wavelength long, is known as the half-wave dipole antenna. The antenna was designed for resonating at the frequency of 2.6 GHz. For the simulation and design calculations CST is used. In this project various factors of antenna such as the return loss, standing wave ratio from Smith charts, Real power Vs Frequency, VSWR, E-feld and H-feld distribution, gain and radiation pattern are also evaluated. Index Terms—Dipole Antenna, CST MWS Introduction The most common practical wire antenna is the dipole antenna. The dipole antennas may be categorized as Hertzian dipole, half-wave dipole, small dipole etc. The most balanced and commonly used type of antenna is the dipole antenna. It can be used alone as well as it is incorporated in many other antenna designs. For the wireless communication of high-speed data for mobile phones and data terminals, Long-Term Evolution (LTE) is considered as a standard and is commonly marketed as 4G LTE. According to the principle of the GSM/EDGE and UMTS/ HSPA network technologies a different radio interface together with core network improvements are developed to increase the capacity and speed. LTE is being gradually developed to ensure that future requirements and expectations are met and planned in the best possible way. LTE is critical to delivering lower cost per bit, high-performance connectivity and user experience required to tackle mobile broadband challenges such as device development, data-intensive services and the implementation of new machine-to-machine (M2 M) applications [1]. Analyses of the advantages and disadvantages of the alternatives of the small monopoly antenna design discussed on[2] such as meandered line antenna, inverted-L antenna, inverted-F antenna, planar inverted-F antenna, and multiband antenna consisting of different types of radiators for performing multifunctional operation of L TE-USB antennas. The molded interconnect device (MID) technology is used to design of a long-term evolution (LTE) antenna presented on [3] as well as its integration on the 3D surface of the mounting compartment of the automotive roof antenna. This antenna provided an input matching better than 10 dB in the desired frequency band and exhibited an unidirectional radiation characteristic in the horizontal plane. This antenna provides an input of more than 10 dB in the desired frequency band and has an unidirectional radiation characteristic in the horizontal plane. The design of a long-term evolution antenna is therefore investigated on [4]. It is designed to be mounted under a standard plastic cover on a car’s roof. The antenna operates at a wide frequency band (from 698 MHz to 960 MHz and from 1470 MHz to 2700 MHz) in small mounting volume and it requires no matching network. In [5], a simple half-wave dipole antenna has been designed and analyzed for wireless applications. The Resonant frequency for the dipole antenna was 5 GHz and as a simulation tool CST Microwave Studio (MWS) has been used. A simple half-wave dipole antenna for wireless applications has been developed and analyzed in [5]. In this project the resonant frequency for the dipole antenna was considered as 5 GHz and CST Microwave Studio (MWS) was used as a simulation tool. Various researches that also discussed different applications, such as [6]-[8], can be done using dipole and half wave dipole antenna. The general construction of a half-wave dipole antenna is shown in Fig.1. Fig. 1. Half-Wave Dipole Antenna There is a gap between two halved wave dipole antenna arms for feeding purposes. Here, the length, thickness and feeding gap of the antenna is denoted by L, D and g. The radiation resistance of the half- wave dipole is 73 Ohm and it matched with the line impedance [9]. The main purpose of this paper is to design and simulate a half-wave dipole antenna by using CST simulator and to operate at 2.6GHz with high gain in LTE (4G) applications. II. DESIGN PARAMETERS OF HALF-WAVE DIPOLE ANTENNA The dimension of the antenna is changed according to the resonant frequency and the resonant frequency is taken as 5GHz. several Mohammed Mynuddin et al., J Electr Eng Electron Technol 2020, 9:5 DOI: 10.37532/jeeet.2020.9(5)e.180
