An antenna is provided with a wire loop having a tapered end with the antenna perpendicular to a base plate. Insulating rods extend from the plate to lock the loop. Wire radials are directed horizontally and circumferentially from the metal base plate to metal stakes secured in a terrain. The base plate is part of a transmission line assembly that also includes a clamp, an S-shaped plate, an input jack and an L-shaped standoff insulator. The antenna is powered from the input jack to the loop. A beam pattern is generated by the loop section, base plate, wire radials and the Earth. Deviation of the beam pattern depends on soil properties of the terrain. To transfer power when the antenna is mounted on a terrain with unknown dielectric properties; a compensation network is provided.

A system includes a housing operably coupled with a vehicle system, and a vehicle monitoring system disposed within the housing comprising a wireless communication device including an antenna configured to wirelessly communication data signals. One or more ground radials are electrically coupled with the wireless communication device and conduct the data signals from the wireless communication device. The one or more ground radials form a ground plane of the antenna while the vehicle system is moving and the antenna is wirelessly communicating the data signals.

The combined antenna for satellite and terrestrial radio communications includes: a support structure (1); a “crossed dipole” compact broadband satellite antenna (10), in turn including a pair of dipoles (11,12), which extend from the support structure (1), and which are substantially perpendicular to each other and connected so as to be electrically out of phase. A broadband “monopole” antenna (50) for terrestrial communications is included, having a plurality of linear electric mass elements (52) extending radially from the support structure (1) to provide an electric mass surface (53), and a radiating arm (55) is also included extending from the support structure (1) away from the electric mass surface (53). The radiating arm (55) is arranged around the central column (2) and includes thread-like radiating elements (56); and the dipoles (11,12) further include one or more thread-like dipole elements (111,112), arranged to define a flattened configuration of the respective dipole (11,12).

A compact millimeter-wave radio system is comprised of an antenna body with reflector region and waveguide region all made from a single piece of material, and a radio receiver that is mounted on a substrate which is mechanically fixed to and held by the waveguide region. The system presents compact, relatively inexpensive, and relatively effective heat dissipation, solution for receiving and transmitting millimeter waves.

An antenna apparatus has a sleeve antenna. The sleeve antenna has an internal conductive member, an external conductive member, an insulating member, and a mountain-shaped conductive member that is electrically connected to the external conductive member. The mountain-shaped conductive member expands radially from an upper edge towards a lower edge. The internal conductive member protrudes higher than the external conductive member above the upper edge of the mountain-shaped conductive member.
