Design of a Dual-band Ring Printed Antenna Array

In this article, a novel design is proposed for a linear printed antenna array with ring radiating elements, able to operate over a wide operating band at X- and Ku-band. The simulation was conducted using Agilent ADS and Momentum software. The printed...
May 9, 2006
With recent advances in telecommunications, the use of microstrip antennas is increasing for a wide range of modern microwave systems. This is mainly due to the features of microstrip antennas: low profile, lightweight, conformable to nonplanar surfaces, and easy and inexpensive mass production. They are well suited for integration...

Synthesis of a Planar, Coupled-line Marchand Balun with Emphasis on Balance

May 9, 2006
The Marchand balun may be one of the most popular forms of microwave balun used to generate a balanced signal. In particular, the planar coupled-line Marchand balun shows good compatibility with microwave integrated circuits (MIC) and monolithic MICs (MMIC). 1 Numerous studies about its design and analysis have been...
