Abstract

The invention discloses a low-profile ultra-wideband indoor communication plane structure antenna. The invention includes a dielectric plate, a metal patch, and a metal grounding plate; various lumped circuits such as resistors and inductance circuits are loaded in series and parallel between the metal patch and the metal grounding plate, and the feeder is connected in series by a second resistor and an inductor of different lengths. The microstrip line is connected to the metal patch, and the ground of the feed line is directly connected to the metal ground plane. The input impedance of the antenna is effectively improved, the bandwidth of the antenna is widened, and the gain of the antenna is improved through the mixed series loading technology of the resistance and inductance and the parallel loading technology of the resistance. The invention realizes the low section characteristic of the antenna, realizes the ultra-wideband frequency coverage of 100-3000MHz, and has higher gain in the working frequency band.

Description

technical field [0001] The invention relates to an indoor antenna of a mobile communication system, in particular to an ultra-wideband indoor planar structure antenna loaded with a lumped circuit. Background technique [0002] As people's requirements for communication quality are getting higher and higher, the characteristics of multi-band and multi-system coexistence in mobile communication require indoor antennas to cover as many frequency bands as possible at the same time. In addition, due to the special indoor environment, the indoor antenna is also required to have low-profile characteristics, so as to conform to the shape of the building and to design the interior beautifully. However, at present, a general indoor antenna can only cover a specific frequency band, and its profile is high and its size is relatively large, which cannot meet the requirements of ultra-wideband and low profile. Although the low-profile feature of the planar structure antenna meets the sma...
