As a result of further research, antennas using metamaterials have been published. Planar leaky-wave antennas using transmission-line metamaterials have been reported with continuous beam scanning. 1-3 Feeding networks of microstrip patch arrays using transmission-line metamaterials have been designed, 4 which removes the inherent pattern squint resulting from the traditional...

In many quarters it is expected that Long Term Evolution (LTE) will be the next generation standard or the 3.9 generation (3.9G) mobile phone standard, which could be introduced as early as this year. The LTE advantage is a very high-speed data transfer capability of up to 326 Mbps...

Nearfield Systems Inc. (NSI) has developed a new spherical near-field scanner, NSI-700S-300, that is capable of testing stationary antennas over wide angles with accuracies and speeds that historically were only available from planar near-field systems. It is ideal for wide angle satellite and radar antenna testing. The planar near-field...

Compact Antenna The HW Series 1/2-wave center-fed dipole antennas and 1/4-wave monopole antennas are now available with standard SMA connector terminations. HW Series antennas are ideal for applications requiring a compact, low-cost antenna solution. These antennas attach using an FCC-compliant RP-SMA connector or the newly available standard SMA connector....

"Recession 101" andYour Career There is no doubt that the economy has affected the industry. Jobs have been lost, careers changed and the financial status of many has been severely affected. The one good thing I have learned from the “Recession 101 Class” is that recessions test us, but...

Microwave Journal mourns the passing last month of William “Leo” Bazzy, co-founder of Horizon House Inc. and Microwave Journal , at the age of 89. Mr. Bazzy was this magazine’s first publisher, and served as president and chairman of Horizon House for more than 50 years. He also founded...

RFMD has developed a portfolio of Gallium Nitride (GaN) on Silicon Carbide (SiC) high power amplifiers and just recently released the first product from a family of discrete unmatched power transistors. The RF3931 is a 48 V, 30 W high power discrete transistor that operates in the DC to...

Northrop Grumman Corp.’s Sperry Marine business unit has been awarded a contract to supply navigation radar systems for eight new US Navy nuclear attack submarines. The firm, fixed-price contract, valued at $20.9 M, was awarded to Sperry Marine by Naval Sea Systems Command, Washington, DC. The contract calls for...

The US Department of Defense’s Missile Defense Agency (MDA) awarded Lockheed Martin a $1 B contract for continued development and evolution of the Aegis Ballistic Missile Defense (BMD) Weapon System. Under the contract, Lockheed Martin’s Surface-Sea Based Missile Defense line of business, in Moorestown, NJ, will design, develop, integrate,...
