                                                                        Introduction                                                                            

Standard gain horn antenna OLB-284-20 WR-284 is also known as a waveguide horn.
This WR-284 standard gain horn antenna has a 20 dB nominal gain and a square cover flange. Our 20dB WR-284 horn antenna has a minimum frequency of 2.60 GHz and a maximum frequency of 3.95 GHz.
Standard gain horn waveguide antenna OLB-284-20 has a vertical beam width of 31.3 and horizontal of 32.1degrees at 3 dB.

The S band is a designation by the Institute of Electrical and Electronics Engineers (IEEE) for a part of the microwave band of the electromagnetic spectrum covering frequencies from 2 to 4 gigahertz (GHz). Thus it crosses the conventional boundary between the UHF and SHF bands at 3.0 GHz. The S band is used by weather radar, surface ship radar, and some communications satellites, especially those used by NASA to communicate with the Space Shuttle and the International Space Station. The 10 cm radar short-band ranges roughly from 1.55 to 5.2 GHz. The S band also contains the 2.4–2.483 GHz ISM band, widely used for low power unlicensed microwave devices such as cordless phones, wireless headphones (Bluetooth), wireless networking (WiFi), garage door openers, keyless vehicle locks, baby monitors as well as for medical diathermy machines and microwave ovens (typically at 2.495GHz).

Wireless network equipment compatible with IEEE 802.11b and 802.11g standards use the 2.4 GHz section of the S band. Some digital cordless telephones operate in this band too. Microwave ovens operate at 2495 or 2450 MHz. IEEE 802.16a and 802.16e standards utilize a part of the frequency range of S band; under WiMAX standards most vendors are now manufacturing equipment in the range of 3.5 GHz. The exact frequency range allocated for this type of use varies between countries.

In North America, 2.4–2.483 GHz is an ISM band used for unlicensed spectrum devices such as cordless phones, wireless headphones, and video senders, among other consumer electronics uses, including Bluetooth which operates between 2.402 GHz and 2.480 GHz.
Amateur radio and amateur satellite operators have two S-band allocations, 13 cm (2.4 GHz) and 9 cm (3.4 GHz). Amateur television repeaters also operate in these bands.

FAQ

1.What kind of interface do I need ?
We recommend coaxial interface if the SGH frequency below 50GHz. If the frequency up to 60GHz , we highly recommend use waveguide interface.

2.What kind of coaxial interface do you have?
There are kinds of coaxial interfaces ,they are divided by the difference of the frequency.
DC – 18GHz usually we use SMA or Nconnector.
DC-26.5GHz usually we use SMA or 3.5mmconnector.
DC-40GHz usually we use 2.92mm or 2.4mmconnector.
DC-50GHz usually we use 2.4mm or 1.85mmconnector.
DC-67GHz usually we use 1.85mm or 1mmconnector.
UP to 67GHz usually we use 1mm connector.

3.What is the price difference between the antenna with waveguide to coaxial connector or without the waveguide to coaxialconnector.
There are two kinds of price about the antenna with waveguide to coaxial connector or without the waveguide to coaxialconnector. We will give you two kinds of prices.

4.What is the naming convention for standard gain horn antennas?
The horn antenna is named after the waveguide international standard type and the horn antenna gain, for example: OLB-42-10 Among them, 42 represents the WR-42 standard waveguide, 10 represents the horn antenna gain is 10dB.

5.What is the highest frequency of standard gain horn antenna?
At present all the standard horn antenna maximum frequency to 220GHz
