Patch antenna is implemented and analyzed using IE3D.Also bandwidth enhancement and minimization techniques are discussed and explored in detail. The patch antenna dimensions are calculated using design equations. The antenna results show that without any modification, it suffers from narrow bandwidth. The performance of same patch antenna is analyzed by doing various variations in the parameters.

This book gives an excellent procedure for optimizing a compact size, wideband microstrip patch antennas. The technique described in this book is based on using genetic algorithm to optimize the dimensions of a microstrip patch antenna having a ground plate with a special cut. The bandwidth achieved here is very attractive for mobile communication systems. Two software packages were used for this purpose, Matlab 2010 and the latest version of CTS microwave studio.

Microstrip patch antennas were first investigated from the idea that it would be highly advantageous to fabricate radiating elements (antennas) on the same dielectric substrate as RF circuitry and transmission lines. Other advantages were soon discovered to be its lightweight, low profile, conformability to shaped surfaces, and low manufacturing costs. Unfortunately, these same patches continually exhibit narrow bandwidths, wide beamwidths, and low antenna gain.

Besides lot of advantages of Microstrip Patch Antenna some severe limitations like narrow bandwidth, low power output, low gain hindered it to use in some application specially where wideband, high gain & high power is essential. In modern days researchers are concentrated to overcome these limitations. The design of dual or multi-frequency patch antennas are also very much important because any one can use a single antenna instead of two or more antenna operating in the single frequency.

Most methods of express glucose do not require a finger prick, which may not be difficult for people with diabetes. Much research has focused on finding an alternative, a painless, minimally invasive method for glucose monitoring.Meta: Non-invasive measurement of glucose in the blood with vicarious patches. To achieve this goal, the following tasks have been set: 1. Conduct a patent search for glucometers and a literary search for non-invasive methods for monitoring blood glucose. 2.

Microstrip patch antennas are probably the most widely used type of antennas today due to their advantages such as light weight, low volume, low cost, compatibility with integrated circuits and easy to install on the rigid surface. Furthermore, they can be easily designed to operate in dual-band, multi-band application, dual or circular polarization. They are important in many commercial applications. The microstrip patch has few drawbacks such as narrow bandwidth, low efficiency, low gain.

We live in a world of communication, where the wireless communication is a key part. Today the demand of wireless communication increasing day by day. Wireless communication has changed the working environment. It is the transfer of information over a distance without using the electrical conductors or wires. For the communication purpose antenna is used as an important element for transmitting or receiving the radio waves.

In this book, the first part present the simulations and experimental results of a series of patch antennas in wide band. The conception of these patch antennas are realized by software HFSS "Ansoft-High Frequency Structure Simulator" and ADS "Advanced Design System", themselves based essentially on the variation of the shape of the antenna, conductive material, the nature and the thickness of the substratum to have a structure which resounds in the frequencies used for precise applications.

Patch antennas with bulk micromachined GaAs substrate suitable for on-chip integration with active devices are investigated. Advantages of such integrated antennas are increased bandwidth, improved efficiency, etc. Micromachining reduces the surface wave generation whereas Electromagnetic bandgap (EBG) blocks the surface wave propagation. Surface wave is the main hurdle for patch antennas printed on high permittivity substrate used for MMICs like GaAs, Silicon.

Basically in the field of microwave engineering antenna modelling is a major topic. Ultra-wide band technology is a part of radio technology which involves a wide-range of innovations in a short range of field. So it is necessary while developing an antenna for the required transmission. So here we represented our work on patch antenna which includes the modelling of a patch antenna with the inclusion of metamaterials.

Volumetric miniaturization, compactness, light weight, low cost, low loss, improved efficiency, multiband EM responses are basic design-application issues for innovative technique used for microstrip patch antennas(MSA). Current trend in modern researches is to use double negative metamaterial as substrate to meet the stringent requirements. MSAs inherently have narrow bandwidth. The Size reduction and BW enhancement are usually majorly demanded considerations for practical applications.

The introductory topic of this special issue provides a carefully structured, elegant discussion of the fundamental principles of the radiating elements and has been written as an introduction for the nonspecialist and a review for the expert. An analytical method is used to predict the features of the simulation results, implying that within a certain frequency range, negative value of permittivity and permeability is obtained due to metametarials.
