An antenna integral-type transmitter/receiver system to be installed outdoors and used for transmission and reception of radio signals. The object is to provide a small, lightweight antenna integral-type transmitter/receiver system formed of the reduced number of parts and assembling steps. The antenna integral-type transmitter/receiver system consists of a housing having one end surface in which an opening is formed and the other end surface in which an antenna mounting surface is formed, and including a transmitter/receiver function unit formed of a waveguide circuit unit, a high-frequency electrical circuit unit, and an intermediate frequency electrical circuit unit; an antenna connected to the transmitter/receiver function unit mounted on the other end surface of the housing; and a cover member for closing the opening of the one end surface of the housing. The waveguide circuit unit and the high-frequency electrical circuit unit form a first unit. The intermediate frequency electrical circuit unit forms a second unit. The first unit and the second unit are arranged so as to be stacked in the housing.

Antenna integral-type transmitter/receiver system

An antenna assembly has incorporated therein an antenna radome element or component which has a substantially cup-shaped configuration and which is provided with a plurality of concentrically disposed rib members upon the interior surface portion thereof. The rib members serve to not only reinforce the antenna radome element or component across the entire diametrical extent thereof, but in addition, the centermost rib member provides a recessed region or pocket for accommodating or housing terminal wires of the balun printed circuit board. In this manner, the terminal wires of the balun printed circuit board can be accommodated while the overall antenna assembly exhibits low profile characteristics in order to resolve operational spatial constraints or limitations.

An antenna is described which includes a plurality of antennas stacked on top of each other in a compact cavity Input match and radiation gain can be enhanced by the application of a capacitor and inductor in the feed of the spiral lowest in the cavity The antenna can fit into a very compact space while providing circular polarization over the desired bands of the antennas that are isolated

Highly isolated dual compact stacked spiral antenna

A technique employing one or more conformal, spiral antenna for use in a vehicle such as a missile. The technique includes both an apparatus and a method. The apparatus includes a radome or missile body and a conformal, spiral antenna mounted in the radome or missile body. The method is one for use in operating a missile, comprising transmitting and receiving signals through a plurality of conformal, spiral antennae mounted in a radome or missile body. This may include in some variants transmitting and receiving signals through a plurality of conformal, spiral antennae mounted in a radome or missile body; and guiding the missile from information obtained from signals receive through the antennae.

An electronic device includes an antenna enclosure provided with a circuit on which an antenna is etched and a balun circuit for feeding the antenna, itself connected to a microelectronic enclosure fitted with an airtight connection having a sealed glass bead with at least one conducting wire passing through it. The balun circuit has at least two different tracks on each side of a dielectric substrate. At least one immediate electrical contact is provided between the conducting wire of the enclosure and one of the tracks of the balun circuit, at the same time as a direct mechanical fixing of the antenna enclosure to the microelectronic enclosure, accompanied by another connection of the same type or an earth transfer conductor which is connected to the other balun track and is in contact with the microelectronic enclosure.

Connection device between an antenna and a microelectronic enclosure

A waveguide-fed microwave system particularly for cavity-backed spiral antennas for the Ka band comprises a waveguide transmission line; a microwave device having a pair of balanced, parallel feed wires; and a doubled tapered ridge transformer directly connecting the waveguide transmission line to the balanced, parallel feed wires of the microwave device providing a direct symmetrical transition between the waveguide transmission line and the microwave device.
