The demand of small size electronic systems has been increasing for several decades. The physical size of systems is reduced due to advancements in integrated circuits. With reduction in size of electronic systems, there is also an increasing demand of small and low cost antennas. Patch antennas are one of the most attractive antennas for integrated RF front-end systems due to their compatibili...

This paper presents a negative index metamaterial incorporated UWB antenna with an integration of complementary SRR (split-ring resonator) and CLS (capacitive loaded strip) unit cells for microwave imaging sensor applications. This metamaterial UWB antenna sensor consists of four unit cells along one axis, where each unit cell incorporates a complementary SRR and CLS pair. This integration enab...

This paper covers the design and optimisation of fractal antennas for RFID application at microwave frequencies. Basing on the Sierpenski gasket antenna and slot technique we propose a novel structure of Sierpenski fractal antenna which is named Sierpenski Slot antenna. The propose structure present a reduction of size by more than 52% which is very important in the case of TAG RFID antenna.

Cancer as global burden with increasing incidence is a second and among third cause of death in developed and developing economies respectively. Surgery, radiotherapy, chemotherapy, hormonal therapy and immunotherapy are the major management options. Thermal therapy is currently gaining attention as an alternative. Radiofrequency, laser, high intensity focused ultrasound, cryo and microwave abl...

Microwave sensors are robust non-contact measurement devices for industrial and vehicular application. Phased array-antenna modules, located in the front-end of the sensor, are often used to enhance the performance of this device. In this paper, a novel 24-GHz microstrip linear array antenna with beam-scanning and signal-amplification properties are presented. The phase shift section is designe...

Microwave absorber are used in Military application, EMI reduction, Antenna pattern shaping, Radar cross reduction. Frequencyselective surfaces have been most commonly used in the radio frequency region of the electromagnetic spectrum and find use in applications as diverse as the aforementioned microwave oven, antenna radomes and modern metamaterials. One of the most important applic ations of...

Atmospheric pressure plasma produced by a slot antenna with a pulsed microwave excitation was investigated to understand an electric field influence on hydrogen Balmer- (H) spectral profile using spaceand time-resolved optical emission spectroscopy. Paralleland perpendicular-polarized H emission line profiles with respect to the microwave electric field direction were measured by a polarizat...

Microwave imaging is one of the most promising techniques in diagnosis and screening of breast cancer and in the medical field that currently under development. It is nonionizing, noninvasive, sensitive to tumors, specific to cancers, and low-cost. Microwave measurements can be carried out either in frequency domain or in time domain. In order to develop a clinically viable medical imaging syst...

Dielectric Resonator Antennas (DRAs) have received increased interest in recent years for their potential applications in microwave and millimeter wave communication systems. DRAs are normally used with the support of a ground plane. The radiation and impedance properties therefore depend not only on their physical dimensions and dielectric properties, but also on the size of the ground plane. ...

Microstrip Patch antenna is generally used in a number of antenna systems because of their low profile, light weight, low cost, compactness etc. Patch antenna is also used with Microwave IC’s and Monolithic Microwave IC’s because of its compatibility. Reconfigurable band notches in UWB antennas are dynamic research area. The advantage of the antenna with reconfigurable band notch is to efficien...
