We have all seen Printed Circuit Board (PCB) antennas: those squiggly bits of traces on PCBs connected often to a Bluetooth, WiFi or other wireless communication chip. On modules like for the ESP8266 ...

Use this fm antenna amplifier in areas where the signal reception of FM stations is too bad. This circuit is just the right thing to do it. It is designed in such a way that the supply current ...

A new type of device—a hybrid antenna with electronics developed by electrical engineers at the Georgia Institute of Technology—puts several transmitters and receivers on the same IC chip or package, ...

Non-Foster circuit design offers a transformative approach to overcoming the intrinsic limitations of traditional passive matching networks. By utilising active elements to generate negative impedance ...

This car antenna amplifier can be used up to 70 MHz and is specially designed to boost the weak signals captured by the car antenna. It has a high input impedance and a low noise figure. The total ...

Evolving communication systems are driving developments in the RF/microwave industry. The large umbrella of 5G focuses on supporting three main technologies: enhanced mobile broadband, which is the ...

A new simpler, cheaper and potentially more effective way to prevent radio antennas from picking up unwanted signals has been created by researchers in the US. With further development, the technique ...

II. IN a previous discourse explanations were given of the property of a closed or partly closed antenna of radiating more in some directions than others, and the action of Marconi's bent antenna was ...
