RF energy harvesting is a viable substitute for collecting energy directly via RF renewable resources for portable devices in the field. In this paper, a novel bandwidth-enhanced, compact, low profile Hybrid/Compound single feed frequency, polarization, and radiation pattern reconfigurable microstrip patch antenna is presented to collage a large am...

A printed and compact size antenna having functionality of frequency and pattern reconfigurability is presented in this work to be operated at 28 GHz for 5G communications. For the desired goal, antenna is incorporated with three PIN Diodes as a switch. The beam swapping of the antenna is guided by Switch 1 and Switch 2 and the frequency is control...

Reconfigurable antennas have received much attention in RF energy harvesting models owing to their selectivity for operating frequency and polarization. The characteristic of having frequency selectivity and polarization selectivity can be termed as frequency diversity and polarization diversity, respectively. This paper investigates a rectenna dev...

This study proposes a novel reconfigurable antenna for the millimeter-wave frequency spectrum. The proposed hybrid reconfigurable antenna is designed to reconfigure antenna parameters in compliance with wireless application specifications, such as frequency and radiation patterns. PIN Diodes as a switch are used to monitor the reconfiguration featu...

This paper discusses a review of frequency reconfigurability through switches for 5G applications. A new switching technique (varying values of lumped parameters) for frequency reconfiguration is analysed and validated by investigation a difference between a simple (non-reconfigurable) and a reconfigurable antenna for 60 GHz resonant frequency. Dif...

This paper proposes a novel radiation pattern reconfigurable antenna for 5G (Fifth Generation) applications. A rectangular patch is enclosed by a hollow rectangular radiating structure. The patch is connected to the rectangular structure by two switches SW1 and SW2, which will, in turn, provide three different radiation patterns, Modes, depending o...

A novel printed and compact profile monopole antenna with hybrid reconfigurability structure for switching the resonant frequency and direction of maximum radiations is proposed in this research work. A novel mathematical model for the architecture of Reconfigurable Patch Antenna (RPA), considering input impedance, bandwidth, antenna gain, antenna...

This paper presents a novel combo-reconfigurable architecture for the frequency and radiation patterning of a novel antenna system for future fifth-generation (5G) millimeter wave mobile communication. The tuning system independently controls the frequency and radiation pattern shifts, without letting them affect each other. The proposed antenna co...

In this paper an artificial magnetic material known as High Impedance Surface (HIS) is used for the performance evaluation and design of wearable patch antenna. HIS is actually a new type of ground plane that has considerably high surface impedance. Hence surface wave propagation on the ground plane is not supported. The use of HIS is now rapidly i...

All antennas in which frequency and radiation patterns can be modified in a reversible and controlled manner are known as reconfigurable antennas. They are different from other antennas, as their mechanism of reconfiguration is located within the antenna and not controlled by an external beam. For reconfigurable antennas, the potential is not to in...

In this paper a multiband miniaturized antenna is analyzed in close proximity to human head. The portable devices in modern Personal Communication System (PCS) uses frequency bands for 3G services in the range of 1.9-2.1 GHz. Most of the handheld devices used for the Wi-Fi applications is 2.45GHz. Integrating both features in a single miniaturized...

This paper proposes schemes for fault detection and isolation in a multi-fault setting. Now-a-days, sensor fault and failure are important issue in various wireless sensor networks. This works suggests a few algorithms based on simple phenomenon of data fusion. Initially, a mutual consensus has been developed among followers (e.g. UAVs in this case...

Linear Parameter Varying (LPV) system is an important class of system, as it covers many physical systems. In this paper, the routine Kalman filtering scheme derivations are entertained to modify for generalized LPV systems. The original system is unstable, for controlling purpose a state-feedback controller is employed. For simulation purpose, a r...
