This paper presents the gain improvement of a sector antenna for mobile phone base station by using the new technique to enhance its gain for microstrip antenna (MSA) array without construction enlargement. The curved woodpile Electromagnetic Band Gap (EBG) has been utilized to improve the gain instead. The advantages of this proposed antenna are reducing the length of MSAs array but providing ...

Adaptive antenna arrays have recently been introduced to cope with the high capacity required by the 3 generation (3G) wireless communications systems. As adaptive antenna arrays focus narrow high gain beams towards the desired user and nulls towards interferers, both coverage and capacity of the network can be improved. To establish the performance gain that a smart antenna can deliver in a 3G...

This paper proposes the compact microstrip antenna with high gain and broad bandwidth by using Bi-polar mechanism. In this mechanism the surface is increased and the losses are reduced. This antenna uses the MATLAB simulator to calculate the parameters and from results it is found that the bandwidth is wider by using this mechanism. This antenna is used for C-Band application, which is the part...

Miniaturized structure and high directive gain performance of a patch antenna are primary requirements for modern wireless communication systems.

Objective of this study is to enhance radius of curvature of return loss, input impedance & explore SWR and radiation pattern. Hollow CDRA has been used instead of single-element CDRA to achieve the above mentioned goal. The impedance bandwidth of a high permittivity hollow cylindrical dielectric resonator antenna excited by micro-strip lines was significantly improved by modifying the feed geo...

A novel monopole internal antenna for mobile handsets is presented. The antenna, called the MB antenna, is a modified monopole whose radiating element is implemented in parallel proximity of a ground plane hence allowing for use as an internal antenna in handset applications. Simulation studies indicate that the proposed MB antenna has superior performance over PIFA antennas commonly used in mo...
