However, it might surprise you that direction finding is nearly as old as radio itself. In 1888, Heinrich Hertz noted that signals were strongest when in one orientation of a loop antenna and ...

Designs vary, but a lot of them seem to sport a CA-C03 ceramic chip antenna at one end of the board to save space. Unfortunately, the lack of free space around the antenna makes for poor RF ...

Disconnect the loop antenna from the RF signal generator or disable its RF output ... the frequency up or down by 0.01 Hz causes the meter indication to reverse direction, indicating you’re as close ...

Many years ago, the active whip antenna and the active loop antenna became popular in AM/MF radio receiving ... or for off-air rebroadcast at a transmitter site. The recovered RF signal level ...

In order to improve capability and reduce cost in a terrestrial direction ... the antenna and monitoring system, such as the SwRI-developed Scout™, a portable, wideband radio frequency (RF ...

AOR USA has added a highly sensitive and directional “loop” antenna to its product line ... noise signals away from the desired direction. They are also very useful for locating the direction ...

Aimed at conventional IoT applications, the ISP1907-LL RF module from Insight SiP provides Bluetooth 5.1 communication for long-range direction-finding connectivity ... 8×8×1-mm module with its ...

The generalized antenna efficiency is divided into three categories: RF efficiency refers to the proportion of RF energy that an antenna converts into electromagnetic wave energy to the RF energy ...
