Abstract
Rectangular Patch Slot Antennas RPSA are getting becoming more likable and popular for practice in wireless implementations such as RFID applications especially in the UHF band thanks to its low-profile structure. This kind of antenna is able to deliver large communication distances but this antenna coverage is very weak which is part of the main drawbacks of these antennas. In this paper, Rectangular Patch Slot Antenna RPSA with different slots has been designed and simulated to be suitable for RFID applications. Circular polarized CP antenna that has been designed to use feed structure with vertical ground encircling a radiating component. The feeding method to feed this antenna is coaxial probe. The paper will concentration on both substrate materials Roger 4350 and FR4 Glass-Epoxy material to model and simulate the designs. The other factor of the design is the patch antenna will cut at the four truncated corners to enhance the antenna gain which will affect considerably the operating frequency. This paper aims to show and find the best feed point area that has an exceptional antenna return loss (S11) and high gain. S11 describe the power reflected from the antenna, which is known as the reflection coefficient S11 must be ≤ -10dB. The design and simulation results of RPSA has been done by high frequency simulation system (HFSS 13.0).
Highlights
Nowadays, Information and Communication Technology ICT development and delivery a lot of various of networks technologies and their application such as antenna systems which are widely use today such as satellite, radio frequency Identification Radio Frequency Identification (RFID)[1], radio frequency RF and communication networking system and even at health care
There are many types of antennas which play a vital role in communication technology which is Micro-Strip Patch Antenna MSPA one of them but the primary concern type in this paper is Micro-Strip Patch MSPA antenna
MSPAs have different shapes for different applications and one of these shapes is Rectangular Patch Antennas RPA which will be suitable for RFID applications
Summary
Information and Communication Technology ICT development and delivery a lot of various of networks technologies and their application such as antenna systems which are widely use today such as satellite, radio frequency Identification RFID[1], radio frequency RF and communication networking system and even at health care. MSPAs have different shapes for different applications and one of these shapes is Rectangular Patch Antennas RPA which will be suitable for RFID applications. RPA and Rectangular Patch Slot Antenna RPSA are prevalent reproduced tuned antennas for wireless scheme of RFID. The main concentration of this paper will be on a RPSA integrated design modelling novelty devoted entirely for mainly RFID applications with optimized Return Loss (S11) and total antenna gain performance[4]. To model and simulate RPA and RPSA antenna systems by employing HFSS simulation environments with few design techniques that would present higher gain than other counterparts which will offer high sensitivity and better antenna pattern that would be applied for RFID applications effectively and efficiently
