In this paper, design, simulation and optimization study of a 1×2 circular microstrip patch antenna (MPA) array for next generation 802.11ac wireless LAN (WLAN) is presented. The IEEE 802.11ac is a set of MAC layer enhancements for higher throughput in the 5GHz band. This emerging standard provides wider channels, higher throughput and efficient use of spectrum. The proposed antenna array is designed...
In this paper, the design, simulation and optimization study of a rectangular microstrip patch antenna (MPA) for ultra wideband (UWB) wireless body area network is presented. The UWB technology provides wideband wireless communication using very narrow pulses and at very low spectral densities. The Federal Commission of Communication allocates the bandwidth of ultra wideband from 3.1GHz to 10.6GHz...
In wireless sensor networks (WSN) the medium access control CSMA/CA uses binary exponential backoff (BEB) algorithm to minimize collision among the contending nodes. The range of backoff exponent is limited to very small values. This causes channel access collision among the nodes resulting in degradation of quality of service. In this paper improved binary exponential backoff (IBEB) algorithm is...
