While designing a wearable antenna for on-body communications, particular importance is given to lessen the lossy effects of the human body on transmission coefficient. This paper presents experimental and simulation results for two different polarizations of center-fed dipole antenna on human body at mobile communication frequency. The isolated parameter is S21(dB). Early results suggest that vertical...
In design and synthesis of wearable antenna, the isolation of antenna and human body is always given paramount importance because this shielding has a pronounced effect on antenna parameters such as resonant frequency, input impedance and radiation pattern. This paper deals with the effects of different shapes of ground plane of quarter-wave monopole antenna on on-body communications around the human...
In recent years smart antennas are acknowledged as a prominent PHY layer technology, which can be used for spatial multiplexing, transmit/receive diversity, adaptive beamforming and interference cancellation. In this paper spatial multiplexing and reuse (due to interference cancellation) features of smart antennas are considered to improve the throughput of a wireless mesh network. Two novel link...
In this paper we present a routing protocol (Modified HWMP, MHWMP) for IEEE 802.11s WLAN mesh networks with smart antennas that incorporates the optimum selection of the PHY-layer transmission/reception mode (multiplexing, beamforming and diversity). MHWMP adaptively selects between spatial multiplexing and beamforming for data transmission according to the wireless channel conditions. We also modified...
