15 dBi Gain, 1 GHz to 2 GHz, Multi Octave Horn Antenna OBH-1020-15

OBH-1020-15 delivers exceptional performance across the 1GHz to 2GHz frequency range. Structurally, this antenna consists of three main sections: the feed, the double-ridged waveguide, and the radiating horn. The antenna feed includes a connector, a coaxial cable, and a cavity at the end of the waveguide. The inner conductor of the coaxial cable passes through a hole in the upper ridge and connects to the lower ridge, enabling efficient signal transmission. The waveguide flares act as sectoral E-plane horns, with two wedges placed between the flares, enhancing the signal’s propagation. The radiating section is a pyramidal horn, designed to match the double-ridged waveguide with free space, ensuring high gain and low return loss.

This antenna’s design provides advantages such as easy excitation, high gain, directivity performance, and high peak power handling capabilities. It guarantees a bandwidth gain of about 15dBi across the entire band, ensuring steady gain in the dual-frequency band, unlike traditional horn antennas. The specially designed taper for the ridges in the horn ensures smooth impedance variations, optimizing the antenna’s performance. Additionally, comprehensive test data is provided, including antenna direction coefficients, Gain, VSWR, and direction maps, which users can input into their systems for precise testing. Despite its high performance, the antenna is lightweight, weighing only 3.2kg, thanks to its weight-reducing structure, and supports Linear polarized waveforms.

OBH-1020-15 is a versatile tool suitable for several key applications. First of all, ts lower frequency range makes it ideal for television broadcasting, supporting UHF/VHF communications commonly used in over-the-air TV services. It is also highly effective for testing and deploying cellular communication systems, including 2G, 3G, and 4G LTE networks. This antenna is frequently used in IoT (Internet of Things) and LPWAN (Low Power Wide Area Networks) applications, such as LoRa, NB-IoT, and Sigfox, where lower frequencies enable longer-range communication and lower power consumption. The antenna is also well-suited for EMC testing in lower frequency ranges, ensuring compliance with regulatory standards for devices operating in these bands. Additionally, it is valuable for public safety communication systems, including networks for police, fire services, and emergency communication, making it ideal for testing such critical devices.Multi Octave Horn Antenna：https://www.rfecho.com/product-category/rf-antenna/multi-octave-horn-antenna/
