With the advancements in optical and satellite communications for high speed long range data transmissions, serrated antennas plays a vital role. In this work we have designed a Edge Serrated Microstrip Patch antenna used for these applications has been modeled on FR4 substrate as a dielectric medium which has a relative permittivity value of 4.4. The proposed antenna was resonating at two different frequencies in L & S band Microwave frequency ranges. This antenna was fed with coaxial feeding and was designed in a software HFSS.
In this paper a hexagonal patch microstrip antenna with hexagonal slot behaves as a wide band monopole antenna having great return loss. It is designed for 1.1194-2.7078 GHz frequency band with wide bandwidth of 1.5884 GHz and return loss of - 73.63dB. A hexagonal patch with etched ground plane monopole antenna with hexagonal Slot is fabricated on the glass epoxy (FR4 lossy) of dielectric substrate with relative permittivity (εr) of 4.3, thickness of 1.6mm, loss tangent of 0.02 with a ground plane, fed with a 50Ω rectangular microstrip feed line. This prototype antenna having an omnidirectional radiation pattern is measured for frequency range of 0-3 GHz. The novelty of this antenna is that hexagonal patch with hexagonal slot gives it uniqueness in design and also getting a bandwidth approx 1.6 GHz with -73dB Return loss is big achievement in 0-3 GHz frequency Band itself. As the antenna is designed only in 0- 3GHz band, having all such properties in one antenna p
Efter att ha tagit vågad ekonomiska åtgärder för att dra Japan ur lågkonjunkturen, premiärminister Shinzo Abe kan vara på gränsen till ett annat genombrott: ett möte med Kinas President Xi Jinping i nästa vecka på den Asien-Stillahavsområdet ekonomiska samarbete (APEC) samlas i Peking. Under det senaste året har eskalerat spänningar mellan Japan och Kina över öarna i East China Sea (känd i Japan som de Senkaku-öarna och i Kina som Diaoyu öarna). Diplomatiska förbindelser mellan de två länderna har frysts efter 2012, när Japan köpt öarna, och Abe har också kommit under kritik i Kina för hans 2013 besök till Yasukuni Shrine i Japans krig döda, som omfattar andra världskriget krigsförbrytare. Han satte sig på sitt kontor här senaste veckan med The Washington Post Lally Weymouth att diskutera ekonomin, band med Kina och om han har förtroende för President Obama.
An ideal wedding is incomplete without a unique diamond wedding band. If you’re getting married, make sure you buy the most unique set of wedding bands. However, if you think a diamond wedding band will cost a lot more, keep the notion of “diamonds are expensive” away.
Night Shift Entertainment is centrally located in Boston's Artisanal South End. Founded Over twenty Years ago, the company was framed around the success of the wedding industry's most celebrated band, Night Shift.
There was a courageous band of populists in the early 1900s who recognized Seattle’s natural deep-water port was an asset and resource that should belong to the people. In March, 1911, the Washington State Legislature initiated laws permitting establishment of port districts. By September, King County voters approved creation of the Port of Seattle, the first public port of the state.

Wireless mesh networks (WMNs) have gained considerable interest in expanding IEEE 802.11 networks to large-scale enterprise and community scenarios, primarily because of its capability of providing wide-band network access to a significant number of users. However, the mesh nodes are typically limited in resources such as bandwidth, computation power and memory. Capacity limitation is one of the fundamental issues in wireless networks. Excess capacity(EC) is the unused capacity. Here in this paper EC Management techniques are used to improve network performance.
