Problems solved by technology
[0003] The current miniaturization technologies include meandering technology, short-circuit loading, lumped parameter loading, and increasing the dielectric constant and magnetic permeability of the substrate, etc., but the miniaturization of the antenna will affect the bandwidth of the antenna. Generally, the bandwidth will be narrowed. The resonance characteristics become worse, so the bandwidth problem needs to be considered
In addition, technologies such as meandering current and short-circuit loading are based on microstrip antenna technology, and its radiation has strong directionality. However, many mobile terminals require omnidirectional transceiver characteristics, so it is difficult to achieve omnidirectional

Abstract
The invention discloses an omnidirectional terminal antenna. The omnidirectional terminal antenna comprises a radiating unit, a reflecting plate and a feed end and is characterized in that the radiating unit comprises a triangular substrate, one corner of the triangular substrate is supported on the reflecting plate as a supporting point, the triangular substrate perpendicularly stands on the reflecting plate, the front face and the back face of the triangular substrate are respectively provided with a copper cladding layer, plated through holes are evenly distributed in the periphery of the triangular substrate, and the copper cladding layer on the front face of the triangular substrate is connected with the copper cladding layer on the back face of the triangular substrate through the plated through holes. The omnidirectional terminal antenna has the advantages that a non-frequency-changing structure can be formed through a triangular resonance unit, the bandwidth can reach more than 30 percent, and the omnidirectional terminal antenna can be applied to a broadband system. Besides, the substrate integration waveguide technology is applied, the structural size of the antenna is reduced by 2 / 3, and omnidirectional radiation is achieved by omnidirectional terminal antenna.
Description
technical field [0001] The invention relates to a miniaturized antenna applied to a wireless terminal, in particular to a miniaturized PCB antenna with an omnidirectional pattern. Background technique [0002] With the rapid development of information technology and microelectronics technology, the miniaturization of electronic products has become a long-term development trend. In particular, the rapid development of wireless communication technology has further promoted the miniaturization of handheld mobile terminals and wearable products. The miniaturization technology of products is mainly based on the miniaturization of devices. Due to the development of microelectronics technology, the integration of devices is getting higher and higher, so the processing and transmission links of equipment are easy to realize miniaturization. The only major constraint is wireless electronics. The device for product miniaturization is the antenna. The structural size of the antenna i...
