GPS (global positioning system) antenna capable of simplifying debugging

Abstract

A GPS (global positioning system) antenna capable of simplifying debugging consists of a long conductor (1), a short conductor (2) and a tail end adjusting circuit (3), wherein the long conductor (1) and the short conductor (2) are respectively arranged on two parallel planes and are non-intersected with each other. The long conductor and the short conductor are respectively coiled, bent and engaged in permutation and combination of multiple coiled units and bent units, which are connected in series. The head end of the long conductor (1) is connected with a signal ground end (G) of a radio signal, the head end of the short conductor (2) is connected with the signal end (S) of the radio signal; the tail end of the long conductor (1) is connected with the tail end adjusting circuit (3); and the tail end of the short conductor (2) is suspended. By using an electromagnetic material as a substrate, the design purposes of high radiation property, good frequency response and small size are fulfilled. According to simulation detection, the product is excellent in property, reasonable in shape structure, low in energy consumption, environment friendly, especially beneficial to mass industrial production, low in production cost and very wide in market prospect.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a GPS antenna. Background technique [0002] GPS antenna is a key component of GPS products in the fields of communication, navigation and positioning. Its radiation efficiency, directivity, bandwidth, impedance matching characteristics, size and manufacturing cost have a great impact on GPS products. At present, the market strictly requires GPS products to develop in the direction of "light, thin, short, and small", and quantitatively requires its performance standards, accuracy, start-up performance, positioning and tracking sensitivity, and low power consumption of products. Furthermore, higher requirements are put forward for the design of the GPS antenna, which makes it more difficult to miniaturize the design of the GPS antenna. The current GPS antennas on the market are far from meeting market demands in terms of volume, bandwidth, radiation eff...
