UA9BA Design 160m Spitfire antenna The start of the project Sergey UA2FW called me on phone one evening in late August 2020 and invited me to the group of fine operators for the CQWW CW 160m 2021 ...

II. ANTENNA SYSTEM DESIGN AND THEORY For efficient transmission of information, the antenna is one of the most important devices in a battery-powered wireless network instrumentation hierarchy. While ...

At its most compact, the antenna is a hollow ring that stands just over 1 inch tall (2.5 cm), about 5 inches (12.5 cm) across—not much larger than a bracelet—and weighs 1.4 ounces (40 grams ...

Omnidirectional antennas are widely used for mobile communications in the base transceiver station. This letter introduces a high-gain coaxial collinear (CoCo) antenna with a stable radiation pattern.

An integrated hardware and software development kit from TMY Technology aids 5G mmWave beamforming R&D projects. The platform serves as a useful tool for academic courseware preparation, communication ...

See Fig.6 for the layout of the collinear antenna and Fig. 7 for the pattern on 3.550 MHz of this antenna fed in phase. MMANA file #7. Actually, one can feed the two in many different ways. It was ...

The design cycle is a little different when the product is wireless and requires an antenna. Antennas change the design process, because it needs to be located with care, in the best position on the ...
