Wireless Technology : A Growing Expansion Of Wireless Communication Technology

Here first we design a simple rectangular shaped microstrip patch antenna with dimension 14 X 14 X 1.60 mm^3 shown in Fig.1. In this antenna the dimension of patch is 10 X 13 mm^2. We are using microstrip line feed to this rectangular patch with length 4mm and width 1.6mm. By simulating this simple patch antenna we were getting only two frequency bands as shown in Fig2.

The slot is fed by microstrip line because it is easy to etch on the substrate and to seek impedance

The tangential components (seen in Figure 3.11), which are in phase, means that the resulting fields combine to give maximum radiated field normal to the surface of the structure. Hence the edges along the width can be represented as two radiating slots, which are λ / 2 apart and excited in phase and radiating in the half space above the ground plane. The fringing fields along the width can be modeled as radiating slots and electrically the patch of the microstrip antenna looks greater than its

As shown from table.1, if the resonator gap between two parallel couple microstrips transmission lines is small then the

An antenna is a system of similar antennas oriented similarly to get greater directivity in a desired direction.

This paper investigated and designed a RF repeater which will improve the inter symbol interference by incorporating delay between received and transmit signal. This project also reviewed the basics of current Digital Video Broadcasting-Terrestrial (DVB-T) techniques and selected it as a suitable choice for lab experiment. The practical side of this

When selecting an antenna, both the width of the area to be covered and the distance of each link must be considered. These considerations will then determine the type of antenna to use, based on each antenna's signal pattern. Every antenna has a pattern to the signal. This pattern applies both to sending and receiving. By convention, the radiation line used to draw this pattern is placed wherever the power radiating out drops to one half of the power at the antenna surface.

In order to eliminate or minimize problems caused by multipath wave propagation, a new technology has been introduced and it is Smart Antenna Technology. There are three forms of smart antenna, known as SIMO (single input, multiple output), MISO (multiple input, single output), and MIMO (multiple input, multiple output).

Micro strip antennas have been widely used in modern communication systems, because of its robustness, planar profile, and low cost. Most of these antennas operate at their fundamental mode, which gives a broadside beam. Micro strip antenna operating at the higher order mode has dual symmetric radiation beams [2]. It is well known that the major drawback of a micro strip antenna is its narrow bandwidth (3%). One of the popular techniques for broadening the patch antenna bandwidth is to incorporate a U slot on its surface as proposed [5].

Antennas are key components of any wireless communication system and it is a device that provides a way for radiation or receiving electromagnetic waves. IEEE standard definitions for antenna (IEEE Std 145-1983) defines antenna as a means for radiating or receiving radio wave. Figure 3.1 shows an antenna as transition device. The arrows displayed in Figure 3.1 shows the electric field lines

The printed antenna is one of the most preferred antenna structures for low cost and compact design of wireless communication systems. In this paper we have investigated a new approach for improving the radiation efficiency and performance of the antennas with the size miniaturization, in particular we have simulated two types of UWB printed monopole antennas for proving this approach with results: circular patch and Compact Miniaturized Semi-Circular patch UWB monopole antennas and in detail investigation was presented on size miniaturization in order to achieve very compactness and high radiation efficiency with out degradation of the functional parameters and overall performance. Simple rectangular microstrip lines are used for feeding the printed monopole antennas. This UWB monopole antenna designed works well for the whole UWB frequency band 3.1-10.6GHz.

UWB antenna are used in a wide frequency range in on-air and ground telecommunication systems [1, 2]. RF and Microwave energy harvesting techniques, UWB antenna design is attracted by Global Navigation Satellite System (GNSS) and Galileo satellite navigation systems [3, 4]. Micro strip patch antenna has various applications in UWB due to its important behavior. Design and analysis of a model of square-shaped wideband monopole antenna is proposed in the Reference [5]. Recently, flat monopoles are proposed and used for wideband schemes [6-9] but their radiation patternis not wholly directional due to
