2.45 GHz Antenna Designs with Impedance Matching Network : NIBE AB, Markaryd, Sweden

Sammanfattning: This master thesis is a part of digitization project at NIBE AB, Markaryd, Sweden.Nowadays, the demand for digitization is increasing. One of the main goals ofdigitization is to build smart houses and industries to offer better lifestyles.NIBE is a company which produces heat pumps, water heaters, district waterheaters, digital stoves and etc. NIBE AB is planning to launch their new products witha communication module which helps users to control NIBE AB’s products remotelythrough their personal devices such as mobile phones, remote control devices and etc.The main objective of this thesis project is to improve these communicationmodules by improving their antenna with better design or replacing them with otherkinds of antennas for efficient communication and also accordingly design impedancematching networks for the system.This work presents the integrated results of an antenna for NIBE AB, tuned tocover 2.45 GHz ISM band which will implemented on a communication module. Wedesigned and simulated four types of different Printed Circuit Board (PCB) antennasand we got the better simulation results of Gain, Reflection Coefficient, VSWR andBand Width from these designs.Also, we used different types of substrates in the simulation to get goodresults and design the impedance matching networks accordingly. If we compare theresults with the current monopole antenna and its parameters, we have goodcharacteristic results in most of the aspects.
