ALLGON ANTENNA SPECIFICATION PDF

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 anntenna two frequency bands, including bands having center frequencies in the regions MHz and MHz. In a particular embodiment, which has been tested and proven to give excellent performance, the central portion of the reflector device, between the specificaation 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 in the linear array. The directional antenna is protected by the radome and has a very low SWR on the whole frequency range. The mount allows tilt and swivel. Innovated a RF wired tested bed that simulated a wireless environment for modem and basestation development.

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 anntenna two frequency bands, including bands having center frequencies in the regions MHz and MHz.

In a particular embodiment, which has been tested and proven to give excellent performance, the central portion of the reflector device, between the specificaation 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 in the linear array.

The directional antenna is protected by the radome and has a very low SWR on the whole frequency range. The mount allows tilt and swivel.

Innovated a RF wired tested bed that simulated a wireless environment for modem and basestation development. Our senior design team based in Sweden has extensive experience in antenna solutions design. As a general rule, however, tests have shown that the depth of the groove should be 0. Introduced a planar near field scanner for antenna-to-antenna phase qllgon. Not in stockordered only on customer request, down payment required, delay at c. Various adapters Order No.

The antenna is weatherproof and can also be used outdoors. The dual band antenna according to the invention can be modified considerably within the scope of the appended claims. If you are not sure which connector your card utilizes, please ask the vendor of that card or send us a good macro picture of the connector. Gain ranges from 4. Smarteq nomiated Smarteq receives nomination from a leading forest machine manufacturer A large global forest machine manufacturer… Read more.

Ideal for the PC with the antenna below the desk and without connection to the local WiFi. Ideal antenna for notebooks with radio data modem or traditional telephone cards. The construction of the OMNI is very robust, the antenna is intended to alllgon used aboard yachts and other seagoing vessels. Next generation intelligent work lights Today, Wllgon releases a whole new generation of intelligent work lights based on wireless communication.

The dual band antenna according to the invention, in the preferred embodiment shown in FIGS. We supply some of them and are happy to answer your questions regarding the right cable. Triple Band Device Antenna Sometimes it is very helpful when the antenna is moved to a better location. Flat panel antenna with radome for outdoor installations, 15 dBi gain. Gain 1 to 4 dBi, depending on frequency. Generated measurement techniques for both antenna pattern and RCS measurements in compact and tapered ranges.

Size 25x25cm, weight 1Kg. With such dimensions, it has turned out that the beam width in the upper band, having a center frequency wavelength antena mm, is substantially enlarged so as to coincide with that of the lower band, having a center frequency wavelength of mm.

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. Our panel antennas are made of weatherproof aluminium, screws and other mounting material is made of stainless steel mast diameter max.

Each combined antenna element, e. USB1 — Dual band antenna — Google Patents The antenna as defined in claim 1wherein said at least one combined antenna element comprises at least two patch elements.

For aligment a simple SWR meter is sufficient, or you follow the table of recommended lengths measures in inch. Parallel and series FED microstrip array with high efficiency and low cross polarization. Of course cable lengths longer than 8m are also possible, but require some more planning and calculation. Compact and wideband universal antenna for many applications. Accordingly, a main object of the present invention is to provide a dual band antenna structure which enables a modification of the beam width in the higher frequency band, in particular so as to become close to the beam width in the lower frequency band.

This snazzy housing contains 2 omni-directional antennas which are arranged in an X shape. We would kindly ask you to contact us for a quote.

Wideband equipment antenna with knuckle. This antenna is also suitable for WiFi on 2. Our products are well-known to have a robust design and high reliability. Microwave power is 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 specfication in a second specificcation 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 gain is approx. The beam width of the lower band is allgom very much affected by the relatively small irregularities of the grooves but is rather determined by the total width of the reflector device, this total width being mm in the illustrated example.

High isolation dual polarized antenna system with microstrip-fed aperture coupled patches. This antenna has a protection clas of IP44 when installed. Includes two waterproof rubber gaskets. Data sheet magnet base antenna For other devices we can supply a suitable adaptor. Related Posts.

The antenna as defined in claim 1wherein said groove at each edge portion is defined by longitudinally extending, substantially planar wall portions. Introduced a planar near field scanner for antenna-to-antenna phase calibration. We supply some of them and are happy to answer your questions regarding the right cable. Comes including an 8m low loss antenna cable with SMA connector.
