Abstract

The invention discloses an ultra-broadband antenna capable of shielding various narrowband signal interferences. The ultra-broadband antenna comprises a grounding plate, a dielectric substrate, a feed network and a radiative patch, wherein the grounding plate is arranged on one side of the dielectric substrate; the feed network and the radiative patch are arranged on the other side of the dielectric substrate; the grounding plate adopts a structure that a trapezoid and a rectangle are connected integrally; a rectangular open groove is formed in the upper end of the trapezoid; a stepped bulge is arranged at one end of the radiative patch; a rectangular open groove is formed in the other end of the radiative patch; the stepped bulge end of the radiative patch is connected with the feed network; and a horizontal C-shaped gap is etched in the radiative patch. The ultra-broadband antenna is capable of effectively inhibiting interferences of various narrowband system signals on an ultra-broadband system in WiMAX wireless communication (working frequency band is 3.3-3.7 GHz), C-waveband satellite communication (downlink frequency band is 3.7-4.2 GHz), digital microwave communication (4.3-4.5 GHz) and the like. The antenna is small in size, simple in structure, easy to manufacture and suitable for wireless communication systems and devices, and has a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of antennas, and more specifically relates to an ultra-wideband antenna capable of shielding interference from various narrowband signals. Background technique [0002] In the 1960s, Ultra-wideband (UWB) technology began to emerge, and then developed rapidly. On the other hand, the rapid development of wireless communication provides a broad development space for the proposal and application of various antennas, and antennas based on ultra-wideband technology play an important role in the entire wireless communication system. Ultra-wideband antennas have incomparable advantages in other narrowband communication systems, such as high data rate, low loss, economical and practical, and simple fabrication, and have always been an important topic in the field of communication research. However, with the rapid development of wireless communication and the emergence of various applications, problems such as the sh...
