In this paper, the size of a log-periodic dipole array antenna is reduced using partially applied folded planar helix dipole elements. The proposed antenna shows almost no gain deterioration in the ...

In this paper, a compact log-periodic dipole array (LPDA) antenna is developed at 0.5-10 GHz. This LPDA structure constitutes fewer dipole elements than a conventional LPDA antenna that exhibits ...

When you search "HDTV antenna" on Amazon, you're going to see about 20 to 30 cheap flat-panel antennas made for city homes. Though they all look the same, I found the Channel Master Flatenna ...

The unusual radio pulses were detected by the Antarctic Impulsive Transient Antenna (ANITA) experiment, a range of instruments flown on balloons high above Antarctica that are designed to detect ...

Photonic crystals are periodic optical structures that can control the flow of light. Multiple reflections from surfaces separated by a distance similar to the wavelength prevent an optical beam ...

The OMNI series of combination mast antennas by Poynting come in a variety of configurations including medium and high-gain SISO, MIMO cellular with Wi-Fi/CBRS band support. MobileMark LTM series of ...
