The magnetic loop antenna is a familiar sight in radio amateur circles as a means to pack a high performance HF antenna into ...
Abstract: The acoustically excited antennas based on the piezo-electric effect (PE) have been shown to reduce the size of the long wave communication system transmitter (Tx) to 10 −4 of the wavelength ...
Abstract: Single negative metamaterial designed in MIMO antenna is suitable for portable applications. Metamaterials reduce the coupling at a separation distance of 0.18-wavelength for the MIMO system ...
