The Ministry of Defense of the Sultanate of Oman has announced the signature of the Certificate of Final Acceptance for a contract covering the expansion and modernization of EADS' existing Joint Command, Control, Communication, Computers & Information (C4I) system, OFEQ2000. This follows on from the signing of the outline...

WiMAX is a technology for fixed, nomadic and mobile applications that promises the delivery of broadband wireless access to the masses. For fixed and portable access applications, a delivery capacity of 40 Mbps per channel can be expected for typical cells with a radius of 3 to 10 km....

In recent years, wireless communications have progressed very rapidly. The IEEE 802.16 Working Group has created a new standard, commonly known as WiMAX (Worldwide Interoperability for Microwave Access), for a low cost, broadband, wireless access at high speed, which is easy to deploy. 1 WiMAX technology can reach a...

There is an increasing demand for broadband multimedia components to satisfy the ever-increasing capacity of wireless networks. In particular, for dense local communications, the 60 GHz band for wireless personal area network (WPAN) applications is of special interest for short-range communications, due to the RF attenuation of the atmospheric...

Microstrip patches are an attractive type of antenna because of their low cost, conformability and ease of manufacture. The aperture-coupled configuration 1 also provides the advantage of isolating spurious feed radiation by using a common ground plane. The primary barrier to the implementation of these antennas in many applications,...

The Norwegian Ministry of Justice and the Police has named Siemens as its turnkey contractor for the installation of a new countrywide emergency call network over the next five years and for the operation of the network for 20 years. The new network is based on Terrestrial Trunked Radio...

Cobham Defence Electronic Systems Division has been awarded with the supply of its COM-231 vehicle mounted microwave antennas to the US Army, Navy, Air Force and Marine Corps, over a five-year period. While the award is on an Indefinite Delivery Indefinite Quantity (IDIQ) basis with an initial one-year contract...

Auriga Measurement Systems LLC announced that it has accepted additional funding from White Oak Partners Inc. in order to develop and launch its next generation of products for RF microwave modeling, characterization and test industry customers. After achieving world-wide acceptance in its first two-years, Auriga is now refining its...

The RF to Light 100 rose 2.3% last week, YTD + 2.7% at 2525. The RF Semiconductor market segment jumped 7% in the first 2 weeks with double digit share price increases for Agere, LSI Logic, MEMC Electr. Materials, Atheros, Hittite, Anadigics and Maxim. Space & defense stocks did...

The short backfire (SBF) is a highly effective aperture antenna of simple and compact construction. Basically, it consists of three elements: two parallel reflectors, large and small, spaced a half-wavelength apart, which form a leaky resonant cavity, and a cavity feed (half-wave dipole, 1–3 waveguide or horn, 4,5 or...
