About TQ Antennas
Microwave power sppecification fed from a feed network in two separate frequency bands, the microwave power in a first frequency band being fed via the aperture in the reflector device to a first radiating patch, and the microwave power in a second frequency band the higher band being fed via the aperture in the reflector device and via a coupling patch and a likewise cross-shaped aperture in the first radiating patch to a second radiating patch, which is smaller and operates in the higher frequency band.
The supplied low loss cable has 5m length and is equipped with an SMA connector. The central portion 10 of the reflector device 1 is planar and carries the patches 4 b5 b6 b in FIG.
The dimensions of the grooves are in accordance with the specifications indicated in the first, general part of the description, the width of each groove being Donation to Save the Children Sweden Christmas is all about the children!
Demonstrated numerical accuracy of antenna pattern predictions and S-Parameter performance. The antenna comes including 10m H low loss antenna cable with SMA male connector. The central, planar portion 10 merges with upwardly projecting, outwardly slightly inclined wall portions 1314 and horisontal wall portions 1516which in turn merge with the wall portions 11 a12 a defining the inner wall of the respective groove.
Constructed cost effective tapered and far field antenna ranges.
The antenna is the ideal replacement for the supplied equipment antennas. Window Pass Through To feed the cable into your house without drilling a hole into the wall – here comes the versatile windows pass through cable. With 2m cable and SMA-Connector. The PAD is a true triband antenna providing a substantial increase in range also on these band. Implemented design changes indentified by senior engineering staff.
Comes including universal mount for wall our mast mount and stainless steel mounting hardware.
Antennas for car telephone (GSM), DECT, ISM, data and public mobile radio
Size 50x25cm, weight 1. The spacing between the smaller radiating patches 6 a6 betc.
We have the capabilities to design customized antenna solutions for your needs. Our panel antennas are made of weatherproof aluminium, screws and other mounting material is made of stainless steel mast diameter max. Stubby Antennas or MHz This design leads to very flat and therefore robust and unobtrusive antennas, combined with high gain and high bandwidth. Diameter of base 48mm, total height 45cm. Introduced a planar near field scanner for antenna-to-antenna phase calibration.
This is very useful for a temporary installation like on vacation, when in a hotel, at a conference etc.

Further to the antenna gain you will experience a system gain of at least 10 dB compared to the small built-in antennas by mounting the antenna outside of a building.
Size 25x25cm, weight 1Kg. A dual band antenna of the kind mentioned in the first paragraph is disclosed in the Swedish patent application Allgon ABwherein each dual or combined antenna element comprises aperture coupled, planar, mutually parallel patches being placed one on top of the other and being centered in relation to a central point of a cross-shaped aperture in a ground plane layer serving as a reflector device.
Please look on the bottom side of your card, there you will find the manufacturer’s name. The widening of the beam in the higher frequency band is caused by a secondary radiation, with a horizontal electrical field component, from the edge portions of the reflector device. The exact configuration and specofication of the grooves are of course dependent on the particular frequency bands being used, the configuration of the combined antenna elements, the configuration of the reflector device, and the geometry and material of the cover or radome normally mounted as a protective speciication on the front side of the antenna.
Sometimes it is specificatuon helpful when the antenna is moved to a better location. Smarteq nomiated Smarteq receives nomination from a leading forest machine manufacturer A large global forest machine manufacturer… Read more. This is very easily done with our SMA magnet base ”.
The directional antenna is protected by the radome and has a very low SWR on the whole frequency range.
The antenna has a gain of up to 14 dBi, depending on frequency band. What is claimed is: The antenna as defined in claim 1wherein said at least one combined antenna element comprise at least two elements arranged in a linear array along said central, longitudinal plane.
In a particular embodiment, which has been tested and proven to give excellent performance, the central portion of the reflector device, between the edge portions being formed as grooves, is limited laterally or sideways by lateral, up-standing wall portions and longitudinally along a linear array of seven dual antenna elements stacked patches by metallic aluminium shield wall elements extending transversely in the region between each pair of adjacent dual elements spexification the linear array.
Recently, the demand for antennas for mobile wireless applications has increased dramatically, and there are now a number of land and satellite based systems for wireless communications using a wide range of frequency bands.
Not in stockordered only on customer request, down payment required, delay at c. The radiating patches 5 b6 b can be replaced by other kinds of dual or combined antenna elements, such as dipole structures. If you are not sure which connector your card utilizes, please ask the vendor of that specificztion or send us a good macro picture of the connector.
The radiator is grounded, which protects the radio against static discharge. Includes two waterproof rubber gaskets. Other secondary objects are to provide an antenna structure which is easy to implement in serial production and which is well suited for practical use in base stations operating in at least two frequency bands, including bands having center frequencies in the regions MHz and MHz.
