Abstract In this paper two distinct methodologies in achieving miniaturized antennas for wireless applications are described. One method is based on defining novel topology of radiating elements that can easily be incorporated into monolithic circuits and the other method is based on embedding radiating structures within novel electromagnetic materials. Examples of extremely small planar antenn...

Graphene, owing to its ability to support plasmon polariton waves in the terahertz frequency range, enables the miniaturization and electrical tunability of antennas to allow wireless communications among nanosystems. One of the main challenges in the characterization and demonstration of graphene antennas is finding suitable terahertz sources to feed the antenna. This paper characterizes the p...

Mobile communication have become an important part of telecommunications. Original applications like paging, mobile phones or GPS have shown a tremendous growth, and new applications are emerging every day: tagging, wireless computer links, wireless microphones, remote control, wireless multimedia links, satellite mobile phones, wireless internet. Mobile means light, small, with low energy cons...

Abstract—This paper presents the development of a standard surface mountable ceramic ball grid array (CBGA) package with an integrated patch antenna in low temperature cofired ceramic (LTCC) technology for emerging single-chip 60-GHz radios. It addresses the challenges of low-loss wire bonding interconnections required between the chip and the antenna as well as the package to allow efficient u...

Recently, intravascular catheter probes have been developed to increase signal-to-noise ratio (SNR) for MR imaging of blood vessels. Miniaturization of these catheter probes without degrading their performances is very critical in imaging small vessels such as coronary arteries. Catheter coils have a loop incorporated in their structure and have limitations in physical dimensions and electromag...

An analysis and design of a novel planar antenna in corporation with fractal shaped defected ground structure (DGS) for emergency management has been presented in this paper. The conventional ground plane can be replaced by a Fractal DGS ground plane to get miniaturization and better resonating characteristics. Particle swarm optimization (PSO) has been used to identify the geometrical descript...
