A Broadband Double Dipole Antenna with Triangle and Rhombus Shapes and Stable End-fire Radiation Patterns for Phased-array Antenna Systems

A broadband microstrip-fed printed antenna is presented for phased-array antenna systems. The presented antenna consists of two parallel dipoles of different lengths to obtain two main resonances. The distance between the two dipoles is adjusted to red...
Microstrip antennas have recently gained wide popularity, because they exhibit a low profile, small size, lightweight, low manufacturing cost, high efficiency, and an easy method of fabrication and installation. Furthermore, they are generally economical to produce since they are readily adaptable to hybrid and monolithic integrated circuit fabrication techniques...

Frequency Converters: Understanding the Benefits of Simple and Complex Architectures

Frequency converters are rapidly becoming the only analog building block in a variety of RF and microwave systems. This trend is obvious in wireless consumer products, instrumentation, radar and radar-warning systems, telemetry and secure communications. The advent of synthetic instruments puts frequency converters at center stage within the RF...

A Practical Design of a Low Phase Noise Airborne X-band Frequency Synthesizer

Frequency synthesizers have been well studied, but difficult problems sometimes arise in their practical implementations. The major concern of synthesizer designers is the phase noise. It is critically important in Doppler radar, frequency-agile radar and various communications systems. In such applications, a synthesizer’s phase noise may set the system’s...
