Non‐uniform mesh for embroidered microstrip antennas

Colorful Textile Antennas Integrated into Embroidered Logos

We present a new methodology to create colorful textile antennas that can be embroidered within logos or other aesthetic shapes. Conductive threads (e-threads) have already been used in former embroidery unicolor approaches as attributed to the corresponding conductive material, viz. silver or copper. But so far, they have not been adapted to ‘print’ colorful textile antennas. For the first tim...

Microstrip Antennas

Microstrip antennas have been one of the niost innovative topics in antenna theory and design in recent years, and are increasingly finding application in a wide range of modern microwave systems. This paper begins with a brief overview of the basic characteristics of microstrip antennas, and then concentrates on the most significant developments in microstrip antenna technology that have been ...

Suspended Hexagonal Microstrip Antennas for Circular Polarization

Suspended hexagonal microstrip antenna with a single coaxial feed has been proposed for circular polarization. The configuration has been realized by inserting perturbations along two opposite sides of the suspended hexagonal microstrip antenna. The broad bandwidth of 70 MHz has been obtained corresponding to VSWR < 2 and 3 dB axial ratio bandwidth of 16.2 MHz has been achieved for the suspende...

Reconfigurable Microstrip Antennas for Cognitive Radio

Small dual-frequency microstrip antennas

The characteristics of a dual-frequency compact antenna, which uses a rectangular microstrip patch with a shorting pin, are studied. Compared with the conventional rectangular patch antenna, this antenna can achieve both a significant reduction of antenna size and a dual-frequency operation with a single feed. A detailed parameter study is performed. The theoretical analysis is based on the fin...
