In this paper, we present a method for the synthesis of multiple beams sparse array pattern based on the unitary matrix method (UMP). A Hankel block matrix is constructed from the sample data of the multiple beams pattern, we can obtain the corresponding excitation for each beam and the sparse array element position through the generalized value decomposition of the equivalent matrix pencil. The numerical...
A monopole UWB antenna with band-notched function is presented. The proposed antenna consists of a modified rectangular radiator and a truncated ground plane. To generate a notch around 5.5GHz WLAN band, a quarter-wavelength shorted parallel coupled strip is attached to the feed line. With those designs, the antenna yields an impedance bandwidth of 2.8 to 13.1 GHz (VSWR < 2), while showing rejection...
This paper presents a wideband circular antenna array with a reconfigurable radiation pattern. The array consists of eight TEM horn antennas. The antenna array exhibits an omni-directional azimuthal radiation pattern when all eight ports are excited with signals of the same magnitude and phase. The antenna array is fed through eight reconfigurable bandstop filters and a power splitter. This enables...
On-body communication is of increasing interest for a number of applications, such as medical-sensor networks, emergency-service workers, and personal communications. This paper reviews 60 GHz on-body communication and its benefits and challenges. Two novel low profile high gain, end-fire wearable antennas are then described. They are promising candidates for on-body channels at 60 GHz. The first...
