Abstract
The paper presents an upgraded configuration of compact T-shaped microstrip patch antenna design, simulation, fabrication, and test on 1.6mm FR-4 substrate. The microstrip patch antenna is simulated using Sonnet Software. The proposed design is developed to be used as a transmitting antenna operating at 2.4 GHz radio signals with bandwidth ranging from 2.2 GHz to 2.6 GHz, and with input, match S11 less than -27 dB on 2.4 GHz frequency. The gain of the proposed antenna is 7.28 dB. The antenna was fabricated and measured results match with simulated in terms of frequency but measured S11 is lower due to lossy dielectric FR-4.
Highlights
In the modern IoT world, when we have a lot of smart devices for remote sensing and home automation, in some cases we need to have small suitable antenna for transmitting data to those smart home devices
A lot of papers are introduced and the authors are talking about Wireless Sensor Network (WSNs) operating at 2.4GHz have turned out to be the one of the most exciting areas of research in the past few years [1, 2, 3]
There are many interesting Microstrip antennas and array designs at 2.4Ghz, for Low Energy Bluetooth or RFID [4, 5], but in this paper the focus will be on simple design of transmitting antenna for 2.4GHz radio, which is widely used for remote sensing and remote control
Summary
In the modern IoT world, when we have a lot of smart devices for remote sensing and home automation, in some cases we need to have small suitable antenna for transmitting data to those smart home devices. Most of those devices are used to make our life easier. There are many interesting Microstrip antennas and array designs at 2.4Ghz, for Low Energy Bluetooth or RFID [4, 5], but in this paper the focus will be on simple design of transmitting antenna for 2.4GHz radio, which is widely used for remote sensing and remote control. Input impedance was maintained by formulations on various antenna geometries and Network Analyzer is used to measure this parameter [8]
