In this Project, MSA is designed with dual substrates, one for L-probe & other for radiating patch. 4.1 Design Specifications The three essential parameters for the design of a rectangular Microstrip Patch Antenna: • Frequency of operation (fo): The resonant frequency of the antenna must be selected appropriately. The WLAN

of fractal antenna using Artificial Neural Network. 2.Introduction:- In high-performance spacecraft, aircraft, missile and satellite applications, where size, weight, cost, performance, ease of installation, and aerodynamic profile are constraints, low profile antennas may be required. Presently, there are many other government and commercial applications, such as mobile radio and wireless communications that have similar specifications. To meet these requirements, micro strip antennas can be used

array antenna is implemented to scan in the range of (+-45) degree in wideband. A novel wideband mono conical antenna in the shape of tears drop is implemented with good radiation directivity and frequency response. A dual spiral antenna for ultra wideband capsule endoscope system is implemented. The capsule endoscope system transmits the image data of internal human body to an external receiver wirelessly. This system contains sensors, a tiny camera, LEDs, a wireless IC transceiver and antenna and

expansion of smart antennas systems. There were traditional smart antennas which occupy multiple antennas at receiver, whereas In MIMO system multiple antennas are engaged at both sides at transmitter as well as receiver side. The multiple antennas at the transmitter and the receiver side provide a major advantage over traditional smart antenna systems—in terms of capacity and diversity advantage. The multipath propagation by MIMO system is a remarkably advantage over other antennas system. Moreover

LITERATURE REVIEW 2.1 RECTENNA & ITS COMPONENT A rectenna is a rectifying antenna, a sort of antenna that is used to convert microwave energy or radio frequency energy into direct current signal that can power low sensor devices. They are modelled as a part of wireless power transmission systems that transmit power through radio waves or electromagnetic waves. A basic rectenna, comprises of a microstrip patch antenna with a RF diode. It is nonlinear rectifying element (for example Schottky diode

solution for any given application. The different MIMO formats - SISO, SIMO, MISO and MIMO require different numbers of antennas as well as having different levels of complexity. Also dependent upon the format, processing may be needed at one end of the link or the other - this can have an impact on any decisions made. SISO, SIMO, MISO, MIMO terminology The different forms of antenna technology refer to single or multiple inputs and outputs. These are related to the radio link. In this way the input

What is meant by array? An antenna is a system of similar antennas oriented similarly to get greater directivity in a desired direction. 2. What is meant by uniform linear array.? An array is linear when the elements of the array arespaced equally along the straight line. If the elements arefed with currents of equal magnitude and having a uniform Progressive phase shift along the line, then it is calleduniform linear array . 3. What are the types of array? a. Broad side array

Antennas – antennas serve as interfaces between transmitted/received signals and transmitters/receivers. Depending on the type, shape, and size of the transmitter antenna, the transmitted signal will have directionality and polarization properties. A receiver antenna is designed to match this directionality and polarization so that the transmitted signal can be received. Earth-facing antennas are usually designed to provide a coverage region with a particular contour shape. Typically, horn antennas
