Design and Simulation of Planar Inverted F Antenna (PIFA) for Long Term Evolution Systems

Abstract: In this paper, a new calculator form is designed to calculate fundamental parameters for Planar Inverted F Antenna (PIFA). The special algorithm is configured by MATLAB R2015a software (version 8.5) in the form of a GUIDE programming language to estimate the value of antenna length (La) and width (Wa) by professional software Computer simulation technology (CST) microwave studio (Version 2019)is used to design and study the effects of each parameter in the antenna performance. The designed model was used directly in manufacturing through this method without any optimization or improvement. This antenna fabricated on the FR4 substrate has relative permittivity of 4.3 with a volume of (120601.5)mm3and the proposed antenna is fed by microstrip feeding structure. Simulation results of the (PIFA) show that the return loss, bandwidth, VSWR, and impedance are −52.100dB, 686 MHz, 1.0002and 49.99 Ω respectively at resonant frequency 3.5 GHZ.

Broadband Microstrip Antenna Overview

Abstract: Microstrip antennas are widely used in people's daily life. Microstrip antenna has the advantages of low cost, low profile, small space occupation, and high conformal capability. So the design of microstrip antennas can be encountered in daily life. Microstrip antennas include the military, aerospace, medical, and so on. Microstrip antenna has a wide research space. The three microstrip antennas, U-shaped open slit laminated microstrip antenna, dual frequency circularly polarized laminated microstrip antenna, and non-radiating edge-fed broadband double-layer microstrip patch antenna are mainly introduced to understand the research progress and expectation of today's microstrip antennas. This paper firstly introduces the basic theoretical concept of microstrip antenna, then introduces the cavity mode theory, and then mainly lists and introduces three kinds of designed microstrip antenna structures. Finally, these three types of microstrip patch antennas are analyzed. And the advantages, disadvantages, and development fields of the corresponding types of microstrip patch antennas are introduced. The application determines the structure of the method used, and each design has its strengths. Microstrip antennas always have room for research, and continuous research will be applied to more fields.
