Abstract

The invention relates to an ultra-wide-band omnibearing low-profile discrete embedded dielectric resonator antenna which comprises a dielectric substrate, two equilateral triangle dielectric resonators with the same size, a rectangular monopole and a coplanar waveguide feeding system. A groove of which a size is equal to that of each dielectric resonator is formed at the upper part of the dielectric substrate so as to carry out embedded installation; the lower layer dielectric resonator is embedded into the dielectric substrate so as to reduce a height of a profile; the rectangular monopole not only is used as an antenna, but also is used as an excitation source to be inserted between two layers of dielectric resonators; two symmetric ground planes with sunken parts are positioned at bothsides of the coplanar waveguide feeding system; a 50 omega straight micro-strip feeder line is arranged in the middle of the coplanar waveguide feeding system; the upper end of the coplanar waveguidefeeding system is connected with the rectangular monopole; and a terminal of the coplanar waveguide feeding system is connected with a coaxial joint. The antenna covers a frequency band range of 3.44to 10.85GHz, has a stable gain and high radiation efficiency on the overall working frequency band, and has a profile height of only 1.524mm.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, in particular to an ultra-wideband omnidirectional low profile discrete embedded dielectric resonator antenna, in particular to a combination of discrete embedded equilateral triangular dielectric resonators and rectangular monopole antennas to obtain super An antenna with broadband characteristics, the antenna can be used as an ultra-wideband wireless communication terminal antenna. Due to the embedded design method, the profile height of the antenna is only 1.524mm, which is especially suitable for small and low-profile wireless communication applications. Background technique [0002] As early as 1965, the U.S. military had established the foundation of UWB technology. In the following two decades, UWB technology mainly served the US military. During this time, dozens of UWB systems have been developed by research institutes and companies supported by the U.S. military. In 19...
