Three processes contribute to the antenna's "press-coil" construction: punching, forming, and insert molding. The punching and forming processes permit a flat, rather than wound-wire, coil.

We all hear about the wireless power transmitter/receiver ICs that Texas Instruments, Linear Technology, IDT, Toshiba and countless others have developed for this rapidly growing market. An often ...

As [VA5MUD] demonstrates, a loading coil is simply an inductor that is placed somewhere along the length of the antenna which makes a shorter antenna behave as a longer antenna.

Receiving transponder coils for low frequency antennas capable of reaching a sensitivity of 75 mV/µT in low frequency around 125 kHz. The KT11835 and KTZ1030, part of KOA Speer’s new KT series ...
