In this paper, the CPW fed Z monopole antennas has proposed for Industrial, Scientific, and Medical (ISM) band (2.4-2.48 GHz) applications. To make the designed antenna suitable for implantation, it is printed on biocompatible Al2O3 ceramic substrate. The proposed antenna was simulated by a phantom liquid and imitating the electrical properties of the human muscle tissue. A study of the understanding of the antenna performance as a function of its dielectric parameters of the environment in which it is immersed was performed. Simulations in various slot widths state demonstrate that the antenna covers the complete ISM band. The proposed antenna shows the lower return loss, good impedance matching and high gain compared to other implantable antennas.

A novel approach of analytically and numerically calculating the relationship of directivity with the spacing height of copper grid layer over the patch, termed as radome structure by the present team of authors is presented. Numerous designs and models of radome structure are conceptually solved and evaluated using finite element method (FEM) based High Frequency Structure Simulator (HFSS) software tool. Single copper grid layer over the patch antenna for achieving high directivity is described. Newton's divided difference method is applied on the radome structure for evaluating the performance parameters of the antenna. A global formula is developed to indicate the relationship of the directivity with the spacing height of the patch antenna by varying the distance of copper grid layer and observing its effect on the directivity of the patch using electromagnetic wave solver HFSS.

A Q-band frequency tripler with centre frequency at 42 GHz has been developed. It is a Schottky diode based planar frequency tripler packaged in a compact hybrid Microwave Integrated Circuit (MIC). A commercially available low cost Monolithic Microwave Integrated Circuit (MMIC) based amplifier has been integrated at the output of the tripler to enhance the output power to +13 dBm at 42 GHz for a corresponding input power of +10 dBm at 14 GHz. More than 40 dBc of harmonic rejection has been achieved without using any additional output filter.

In this paper we study the effect of nonlinear apodization techniques on polarimetric synthetic aperture radar (PolSAR) image decomposition. We show that sidelobe suppression in PolSAR images helps in better information extraction through target decomposition techniques, and hence results in better target identification.

This paper presents a dual-mode bandpass filter with asymmetric passband response. Hexagonal shaped Substrate Integrated Cavity (SIHC) has been used to implement the proposed filter. Perturbation technique has been used to realize this bandpass response. The filter has four poles and one transmission zero introduced at the left of the passband. The design has passband insertion loss of 0.65 dB and fractional bandwidth of 5.1% at X-band.

This paper presents non singular and thin cylindrical electromagnetic cloaks which are designed by coordinate transformation based on linear function. The derived material parameters are free of any infinities and singularities at the inner boundary of cloak which is good for its realization. The effects of parameters `s' and `b=a' ratio have been discussed on the performance of cloak. All the designs have been validated by simulation results.

In this proposed paper, I have put in efforts to design a printed bent dipole antenna with an adjustable integrated balun to operate in the X-band. At X-band, this antenna has relatively good electrical properties like less return loss, high gain etc. with immunity to environmental parameters like mist and rain. These characteristics make this antenna an effective communication antenna on missiles.

The process of sparse antenna array synthesis involves the simultaneous minimization of the number of mutually conflicting parameters, such as peak sidelobe level and first null beam width. This necessitates the development of a multi objective optimization process which will provide the best compromised solution based on the application at hand. In this paper multi-objective optimization is achieved using the non-dominating sorting genetic algorithm of NSGA-II. This approach yields much more improved results as compared to single objective optimization approach and at the same time it offers flexibility in choosing the solution based on the Pareto front.
