Abstract:

In this paper, a new formation of modified T shape simple Microstrip patch antenna (MPA) is designed and analyzed for Wi-Fi applications. The proposed antenna operates between the frequencies of 4 GHz to 8 GHz with return loss below -10 dB which almost covers entire C band with standard gain. Besides the proposed antenna is designed to operate at C band and WLAN (802.11/a/b/g) frequency bands by feeding a coaxial probe and the MPA is simulated on Zeland IE3D simulation software using Arlon cu 217LX (lossy) substrate with dielectric constant of 2.2 and thickness of 2.425mm. The dimension of designed antenna consists of 20 × 10× 2.425 mm3 . The proposed antenna resonates at 5.121 GHz for IE3D and 5.78 GHz for CST which can be used in Satellite applications, aircraft, space craft and wireless communication such as WLAN, WiMAX and Wi-Fi. The noted gain and directivity are 5.42929 dB and 6.16506 dBi respectively at 5.121 GHz and Gain and directivity are 4.47 dBi and 5.46 dB respectively at resonant frequency 5.78 GHz for CST. Through simulations better return loss and VSWR (<2) is achieved.

Description:

Wireless communication is rapidly growing part of the communication industry. It has become user-friendly in our society and essential for our daily lives. It gives new sense of mobility to us and revolutionized way to do almost everything with great pleasure. Microstrip patch antennas (MPA) are widely used in ubiquitous industry and it has skimmed attention of the researchers because of various properties like low profile, easy fabrication and integration with circuits, easily mountable on vehicles etc. [9, 22]. These magnificent properties of MPA contribute in the military applications such as missiles, space craft, aircraft and also in the commercial areas such as cellular mobile communications, mobile satellite system and global positioning system. The selection of proper antenna depends on the requirements of the application such as cost, size, gain, bandwidth, efficiency, radiation pattern, frequency band and coverage and it will reduce power consumption and improve transmission efficiency. Wi- Fi is the fastest growing part in the modern wireless communication which gives the users the mobility, freedom and flexibility to move around within a broad coverage area and still be connected to the network [1]. Worldwide electromagnetic spectrum has been allocated for all types of electromagnetic (EM) radiation based on EM wave wavelengths and frequencies where antennas can operate according to the applications of wireless local area network connections (WLAN), and satellite etc. The operating frequency selection for certain antennas in part determines the material that can be used to produce the antenna. There are many materials which is used in antenna such as RT duroid, Arlon Cu, ceramic, steel plate and new artificial materials known as meta-materials has been introduced which exhibits unusual properties that are not available in the nature. Antenna performance can be improved by designing antenna with meta-materials.
