New Types of Microstrip Antennas for UHF Applications

A new technology for the fabrication of microstrip antennas in general and for UHF frequencies in particular
New Types of Microstrip Antennas for the Applications Typically, patch antennas are narrowband and their Q factor is inversely proportional to frequency. The main reason for the high Q factor is that patch antennas are essentially circuits printed on a relatively thin substrate: the higher the dielectric, the higher...

Static Fractional-N: The True Fractional Division Method of Indirect Synthesis

Indirect frequency synthesis using dynamic fractional division vs. static fractional division
Static Fractional: The True Fractional Division Method of Indirect Synthesis A significant development of the indirect frequency synthesis method, called fractional-N, has been developed recently. This article shows that this dynamic method is only one of two possible ways for the implementation of the fractional division idea. The second...
