With the continuous growth of wireless communication service and the constant miniaturization of communication equipment, there are higher and higher demands for the vo...

Future base stations for Spatial Division Multiplex Access (SDMA) will utilize adaptive antenna arrays, capable of identifying the direction of the incoming signal and steering the transmitted beam in appropriate directions. The radiating elements that have been thus far considered for building the antenna array are typically wire dipoles or microstrip patches. This tutorial paper describes a n...

The growing demand of wireless services requires the definition of new standards able to provide an increased degree of mobility for the end user and a higher speed of data transmission. Among emerging standards, one of the most promising is the IEEE 802.16 Wireless Metropolitan Area network Air Interface (generally called Wimax).In last few decade the miniaturization led antenna to be conforma...

Due to their smaller size and light weighted structures patch antennas are accustomed in modern communication Technology. With additional size in reduction, micro strip antennas are commonly used in handsets, GPS receivers etc. This paper presents a novel design of fractal shape patch antenna using U-slot on patch and defected ground structure. Due to slots on patch and ground, tri-band resonat...

In this paper the design, fabrication, and testing of a miniaturized rectangular microstrip patch antenna loaded with DNG metamaterials is reported. The metamaterial is composed of two nested spiral strips and a single straight strip which are etched on two sides of a 5.7 mm×5.7 mm Rogers RT/duroid 5880 with 0.5 mm thickness and dielectric constant of 2.2. Two units of this structure as a doubl...
