This paper presents the development of a rectangular loop microstrip patch antenna integrated with Light Emitting Diode (LED) for Wifi application. The objective to integrate with LED is to have dual applications in a device which illumination and also wireless communication. The antenna was designed at a frequency of 2.4 GHz and Computer Simulation Technology (CST) was used to optimized the position of LED within the rectangular loop antenna. The performances of the antenna in terms of return loss, gain and radiation pattern was verified through simulation by using Microwave Studio in CST. The antenna was fabricated on FR4 substrate with permittivity, εr =4.5 and thickness,h= 1.6mm. The LED integrated within the patch was conducted parallel and was measured by Vector Network Analyser (VNA) to demonstrate the capacity and potential of the antenna. The antennas are reasonably well matched at their corresponding frequency of operations between simulation and experiment.

The limitations in the applications of microstrip antenna lead to wastage in the form of space and functionality. In order to overcome the wastage of space and functionality of the microstrip antenna, the new idea is to make one single device of microstrip antenna which has two application at the same time where it can operates as antenna and the function as lighting source is proposed. Light Emitting Diode (LED) has been chosen as the light source since the characteristic and the structure of the LED are suitable for the integration process. Hence, this paper presents an investigation on the characteristic of an H-shaped patch antenna integrated with Light Emitting Diodes (LEDs).The proposed integrated antenna has been designed and simulated by using Computer Simulation Technology (CST) Microwave Studio Software. It has been fabricated and measured to investigate the performance of the antenna in terms of return loss. The results confirms that the antenna can operate at 2.4 GHz and it works well as an illumination.

Experimental results show that the return loss (RL), bandwidth (BW), voltage standing wave ratio (VSWR) and input impedance (Zin ) are -25.26 dB, 61 MHz, 1.12 and 54.46 Ω, respectively. The antenna operates at 2.42 GHz (from 2.39 to 2.45 GHz), which has good performance in the Wi-Fi, Bluetooth, and ZigBee communications.

A novel butterfly-shaped patch antenna for wireless communication is introduced in this paper. The antenna is designed for wideband wireless communications and radio-frequency identification (RFID) systems. Two symmetrical quasi-circular arms and two symmetrical round holes are incorporated into the patch of a microstrip antenna to expand its bandwidth. The diameter and position of the circular slots are optimized to achieve a wide bandwidth. The validity of the design concept is demonstrated by means of a prototype having a bandwidth of about 40.1%. The return loss of the butterfly-shaped antenna is greater than 10 dB between 4.15 and 6.36 GHz. The antenna can serve simultaneously most of the modern wireless communication standards.

Microstrip Patch

A microstrip patch antenna is designed for a wearable antenna. The performance of microstrip patch antenna loaded with reactive impedance surface (RIS) is described in terms of gain, bandwidth and return loss. The antenna is investigated in two conditions which are conventional microstrip antenna with RIS and without RIS. The designed antenna is also aimed at size reduction therefore it will be suitable for a wearable application. This antenna which is made fully using textile and it is designed for operation in the 2.45 GHz band. The performance of microstrip patch antenna loaded with RIS is described in terms of gain, bandwidth, return loss and radiation pattern. The antenna designed with RIS operates at 2.45 GHz. Bandwidth enhancement is achieved with RIS where the designed antenna can cater frequency from 2.4 GHz to 3 GHz. A gain enhancement is achieved of 20% is achieved compared with the conventional patch antenna. Although the size of the patch is reduced with the introduction of RIS, the overall size of the antenna with the substrate is almost similar to the conventional patch antenna. However, the performance of the antenna is greatly enhanced with the use of RIS.
