Hybrid of monopole and dipole antennas for concurrent 2.4- and 5-GHz WLAN access point

MICROWAVE AND OPTICAL TECHNOLOGY LETTERS, Issue 5 2009
Jui-Hung Chou
Abstract A novel hybrid of a 2.4-GHz monopole antenna and a 5-GHz dipole antenna is presented to provide concurrent 2.4 and 5 GHz band operation for access-point applications. The two antennas are arranged in a collinear structure and printed on a compact dielectric substrate with dimensions 12 mm × 60 mm. The monopole antenna has a meandered radiating strip and is short-circuited to a small ground plane through a shorting strip. The dipole antenna includes two sub-dipoles at the opposite side of a narrow ground plane and fed by a simple T-junction microstrip-line network. The two antennas are closely set with a distance of 1 mm only, yet good port isolation (S21) well below ,20 dB can be obtained. With a low profile, the proposed design can easily fit into the casing of some standard access points and allow the 2.4 and 5 GHz band signals to be simultaneously received or transmitted with no external diplexer required. Good omnidirectional radiation has been observed too. © 2009 Wiley Periodicals, Inc.

Compact hybrid defected ground plane

MICROWAVE AND OPTICAL TECHNOLOGY LETTERS, Issue 3 2005
Md. Nurunnabi Mollah
Abstract A novel hybrid defected ground structure (DGS), which interleaves a photonic bandgap structure (PBGS), is investigated theoretically as well as experimentally. It yields distinct multiple passbands and stopbands. The novel structure can be used either a compact diplexer or a dual stopband filter. With Chebyshev distributions on the interleaved PBGS, the passband and stopband performances improve significantly. © 2005 Wiley Periodicals, Inc.

The In Vitro Characterization of the Erythronolide Mycarosyltransferase EryBV and Its Utility in Macrolide Diversification

CHEMBIOCHEM, Issue 4 2007
Changsheng Zhang Dr.
By capitalizing upon the reversibility of glycosyltransferase-catalyzed reactions, EryBV was characterized in vitro as the erythromycin mycarosyltransferase and the EryBV substrate specificity was investigated. Two-GT (EryBV/AveBI) aglycon-exchange reactions also led to the production of novel hybrid "erythromycin,avermectin" macrolides. [source]

Avoidance by grazers facilitates spread of an invasive hybrid plant

ECOLOGY LETTERS, Issue 2 2010
E. Grosholz
Ecology Letters (2010) 13: 145,153 Abstract Biological invasions greatly increase the potential for hybridization among native and non-native species. Hybridization may influence the palatability of novel hybrids to consumers potentially influencing invasion success; however, the palatability of non-native hybrids relative to the parent species is poorly known. In contrast, studies of native-only hybrids find they are nearly always more palatable to consumers than the parent species. Here, I experimentally demonstrate that an invasive hybrid cordgrass (Spartina) is dramatically less palatable to grazing geese than the native parent species. Using field and aviary experiments, I show that grazing geese ignore the hybrid cordgrass and preferentially consume native Spartina. I also experimentally demonstrate that reduced herbivory of the invasive hybrid may contribute to faster spread in a California estuary. These results suggest that biological invasions may increase future opportunities for creating novel hybrids that may pose a greater risk to natural systems than the parent species. [source]
