A Broadband, High Gain, End-fed Coaxial Collinear Antenna

The Challenge There are a variety of VHF/UHF communication systems that require an omnidirectional antenna which is low-weight, portable, easy to fabricate, and low cost. A vertical collinear array of dipole antennas is a popular candidate for mobile communication due to its omnidirectional radiation pattern. These are currently used in a wide variety...

Transmitting Baseband Signal Through a Narrowband Antenna

An electrically small antenna, ESA, is shown to be equivalent to a RLC tank resonator with either L or C as leaky component or in general L and C leak electromagnetic energy as radiation. In the case that only one of the reactive component is leaking energy, the stored energy in the reactive near field of the antenna is exchanged with the stored energy...

Time Variant Antennas

A time-variant component is incorporated in the antenna structure to reduce the size of the antenna and make it tunable through multiple bands. This results in a small, tunable antenna capable of operation over multiple frequency bands.

Fully Mechanical Radio Frequency Transmitter

All the modern low power radio frequency transmitters contain solid state electronic components which can operate at certain environmental conditions. We are proposing a transmitter which can transmit electromagnetic waves, which are much more tolerant in terms of environmental conditions, especially high temperature applications. There are several...
