Design Smart Antenna by Microstrip Patch Antenna Array

Abstract

Abstract-Smart antennas have been studied extensively this decade because of its low profile structure and formidable rate, thereby creating new and improved services at lower costs. They are extremely compatible for embedded antennas in handheld wireless devices such as cellular phones, pagers etc. Because of its versatility, Smart antenna which is designed by planer array can be used to synthesize a required pattern that cannot be achieved with a single patch element.

Comparison of Circular Sector and Rectangular Patch Antenna Arrays in C-Band

“…In the other side gain and directivity of circular sector antenna array is comparable to gain of [14] it's about 11 dB for gain and 12 dB for directivity.…”

“…The gain of patch antenna was improved for both shapes using array techniques (10 dB for 4 elements) and (14 dB for 10 elements). From comparison with literature [14][15][16], we proved the ability of using circular sector patch antenna array with same performance of rectangular patch with interesting dimension and circular polarization.…”

“…Other designs in bibliography confirm that similar array could be used for smart antenna [14][15][16]. Table 2 shows the obtained simulated results of directivity and gain for liner and planar arrays based on circular sector microstrip antenna and rectangular microstrip antenna.…”

“…In Table 4 we recapitulate characteristics of our proposed array and other array in literature [14].…”

Finite Element Modeling and Design of Rectangular Patch Antenna with Different Feeding Techniques

“…The patch antenna creates a specific conductive structure in the environment. The exclusive property of the microstrip patch antenna is its two dimensional structure [5]. The Patch antenna provide better gain performance as compared to the traditional dipole or monopole antennas utilized in the past [6,7].…”
