It is a whole new world out there for defense companies. Department of Defense (DoD) budgets are under greater scrutiny, and pressure is mounting to reduce spending and change the way the US military does business. Yet new requirements and increasing demands are placed on the military every day,...

The measurements needed for radar differ depending on the job to be done and the type or radar to be characterized. Modern radar designs incorporate complicated pulses that present significant measurement challenges. Improvements to range, resolution and immunity to interference have implemented complex technologies such as phase modulated pulses,...

Microstrip bandgap structures, such as photonic bandgap (PBG), electromagnetic bandgap (EBG) and defected ground structure (DGS), have recently been used to suppress high-order harmonics in antennas, amplifiers and oscillators 1-4 because they are simple to fabricate and have excellent filtering performance. For example, Radisic 1 introduced a wideband power...

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...
