The modern wireless systems call for integrating multiple applications. There are numerous
techniques available to cater these demands. However the need for thin, light weight and …

The design of an aperture-coupled annular-ring microstrip antenna for circular polarization
(CP) is presented. The CP radiation of the annular-ring microstrip antenna is achieved by a …

This paper presents a generalized approach to design an electromagnetically coupled
microstrip ring antenna for dual-band operation. By widening two opposite sides of a square …

In this paper, it is shown how a single-layer capacitive feeding mechanism, consisting of a
small rectangular probe-fed patch, which is capacitively coupled to the radiating element …

The design of a square-ring microstrip antenna with circular polarisation (CP) is presented.
To compact the antenna size and overcome the high impedance problem, the CP antenna is …

Energy harvesting or energy scavenging is basically a conversion process of the ambient
energy into the electrical energy. The ambient energy exists around us in many different …

The multiport network approach is extended to analyze the behavior of microstrip fractal
antennas. The capacitively fed microstrip square ring antenna has the side opposite to the …

The novel design of the circular polarisation (CP) for an annular-ring antenna operated at its
TM11 and TM12 modes is presented. The CP radiations of the proposed design are …

This letter describes a novel compact solution for integrating a Global Positioning System
(GPS) and a Satellite Digital Audio Radio Service (SDARS) antenna in a very small volume …

An electromagnetically coupled feed arrangement is proposed for simultaneously exciting
multiple concentric ring antennas for multi-frequency operation. This has a multi-layer …
