Abstract: A dipole antenna for wide-band communications. Some embodiments relate to a multilayer planar high-gain antenna for ultra-wideband communications having a broadband dipole structure, a tuning plate and a feed arranged roughly parallel to one another and separated from one another with dielectric materials. In one embodiment, the antenna includes four conductive layers, a reflector, which is preferably rectangular, a broadband bowtie preferably of bowtie shape, a feed structure and a parasitic element or tuning patch.

Abstract: A bicone antenna is provided with high bandwidth and beneficial return loss performance. The antenna is dipole based and thus its radiation pattern is not strongly influenced by shape and size of a nearby ground plane. A parasitic element comprising a conductive band encircling the antenna's feed structure improves matching, gain flatness, and makes the antenna less susceptible to detuning.

Abstract: An antenna is provided having a good matching characteristics when immersed in a fluid such as saline water, oil, or other liquids (“the phantom liquid”). In some embodiments, the antenna provides a tight capacitive coupling with the phantom liquid through the use of a higher permeability cover and absence of a gap between the cover and the antenna body. One embodiment employs a tunably capacitively loaded inverted “F” antenna structure. Additional embodiments of the invention provide an antenna tuning system that saves power by utilizing very low duty cycle periodical refreshing charge at a tuning varactor diode coupled to the antenna.

Abstract: A transmitter includes a plurality of devices which processes a transmit signal. Examples of such devices include a variable gain amplifier, a power amplifier and/or a modulator. Some other these devices are gain controllable. Some of these devices are bias controllable. Each controllable device receives at least one analog control signal (gain/bias) which sets operation of the controllable device. A logic circuit receives a specification of the analog control signal and generating a digital control signal based thereon. A digital-to-analog converter circuit converts the digital control signal to the analog control signal for application to the controllable device. The digital control signal generated by the logic circuit comprises a plurality of connected linear segments (a digital piecewise approximation) which approximate the specification of the analog (gain/bias) control signal, and the generated analog control signal is comprised of a corresponding plurality of connected analog linear segments (an analog piecewise approximation).
