Reconfigurable Antenna : Narrowband Frequency Reconfigurable Antenna
Reconfigurable antennas have attracted a lot of attention especially in future wireless communication systems. Superior features such as reconfigurable capability, low cost, multi-purpose functions and size miniaturization have given reconfigurable antennas advantage to be integrated into a wireless systems. In this chapter, two types of reconfigurable antennas are discussed. First, frequency r...
متن کاملFrequency Reconfigurable Conformal Antennas for Wireless Networks
Frequency Reconfigurable antennas have received significant attention for their applications in communications, electronic surveillance and countermeasures, by adapting their properties to achieve selectivity in frequency, bandwidth, polarization and gain. This paper presents the design of reconfigurable conformal antenna for wireless LAN networks. The proposed antenna is suitable for Wireless ...
متن کاملFrequency Reconfigurable Microstrip Circular Patch Antenna for Wireless Devices
In this paper, a frequency reconfigurable circular antenna design and development is proposed for wireless devices. In the proposed design, a circular patch antenna with circular slot using two PIN diodes at the centre frequency 10 GHz was designed and simulated frequency reconfiguration is achieved in the frequency range of 9.69-10.2 GHz and the measured results shows the same effect in the fr...
متن کاملSecure Collision-Free Frequency Hopping for OFDMA-Based Wireless Networks
This paper considers highly efficient antijamming system design using secure dynamic spectrum access control. First, we propose a collision-free frequency hopping (CFFH) system based on the OFDMA framework and an innovative secure subcarrier assignment scheme. The CFFH system is designed to ensure that each user hops to a new set of subcarriers in a pseudorandom manner at the beginning of each ...
متن کاملFrequency Hopping Pattern Recognition Algorithms for Wireless Sensor Networks
Frequency Hopping Spread Spectrum (FHSS) as a communications technique has also been considered as one of security mechanisms to provide a good level of security against eavesdroppers in wireless sensor networking environment. We claim that the version presently used in wireless sensor communications does not yield a high level of security. In this paper, we develop algorithms to break the FHSS...
