Problems solved by technology

In China, a dual-frequency microstrip antenna that can simultaneously work on GPS and Bluetooth has not been proposed; in foreign countries, in July 2005, A.T.M.Sayem et al. Volume published "A dual-band Hilbert slotantenna for GPS and Bluetooth application (a dual-band Hilbert slot antenna for GPS and Bluetooth applications)", in which it is proposed to open the Hilbert slot shape on the radiation patch to realize GPS Dual-band work with Bluetooth, but the structure is more complicated, and the size of the antenna is also larger, which is not conducive to mobile communication

Embodiment Construction

[0012] A preferred embodiment of the present invention is described in detail as follows in conjunction with accompanying drawing: Refer to figure 1 , 2 As shown, the GPS and Bluetooth dual-band microstrip antenna consists of a radiation patch 1, a dielectric plate 2, a feed point 3, three short-circuit pins 4, 5, 6 and a ground plate 8. An E-shaped slot 7 is opened on the radiation patch 1 to make the antenna exhibit a dual-frequency effect. The dielectric plate 2 adopts a low dielectric constant, and three short-circuit pins 4, 5, and 6 are inserted in the dielectric plate 2 to make the radiation patch The sheet 1 is connected to the ground plate 8, and the resonant frequency can be adjusted by changing the positions of the short-circuit pins 4, 5, and 6. There is only one feeding point 3 , so that it is located on the transverse axis of symmetry of the rectangular radiating patch 1 . The unified modeling and simulation of the above-mentioned models is carried out, and the...

Abstract

The invention relates to a GPS and Bluetooth double-frequency and micro-strip antenna. An E-shaped slot is opened on a radiation patch of the antenna and three shorting pins are inserted into a medium plate so as to achieve GPS and Bluetooth double-frequency operation. The three shorting pins in the medium plate connect the radiation patch and a grounding plate, which is equal to three shunt inductors. The resonance frequency of the micro-strip antenna can be adjusted by changing the position of the shorting pins and at the same time, the shorting pins can miniaturize the micro-strip antenna. The invention well achieves GPS and Bluetooth double-frequency operation and can be widely applied in the field of wireless telecommunication technology.

Description

technical field [0001] The invention relates to a GPS and Bluetooth dual-frequency microstrip antenna, which can be widely used in the technical field of wireless communication. Background technique [0002] The development of wireless communication technology is inseparable from the development of antenna technology. Antenna characteristics directly affect the quality of communication. Cellular phones, global positioning systems (GPS), satellite communications, personal communications (GSM900 / DCS1800), Bluetooth and other fields are all There is a need for dual-band antennas that are light weight, low profile, easy to manufacture, and easily conformable. Microstrip antennas have attracted increasing attention and applications due to their thin profile, small size, light weight, easy integration, and low cost. [0003] At present, mobile applications of GPS and Bluetooth functions have become more and more widespread. Handheld terminals with GPS function are very common, a...
