Embodiment Construction

[0011] Below in conjunction with accompanying drawing and embodiment the present invention is further described:

[0012] exist figure 1 In the embodiment, the digital antenna includes a rack antenna 1 , and also includes a modem 2 and a wifi module 3 .

[0013] The rack antenna 1 can be an ordinary Yagi antenna, which is racked outdoors, generally supported by poles, and placed in an open place.

[0014] The rack antenna 1 sends the received analog signal to the modem 2, and the modem 2 modulates it into a digital signal.

[0015] The wifi module establishes a wifi hotspot that can be accessed; generally, a user name and an access key can be set, on the one hand to prevent resources from being arbitrarily accessed, causing local area network congestion, and on the other hand to ensure the privacy of resources.

[0016] When the user's portable digital device accesses the wifi hotspot through its own wifi module, the digital signal is transmitted to the digital device.

Abstract

The invention provides a digital antenna. The digital antenna comprises a frame antenna and further comprises a modulator-demodulator and a WiFi module; the digital antenna modulates received analog signals into digital signals through the modulator-demodulator; the WiFi module establishes an accessible WiFi hot spot; when digital equipment is access to the WiFi hot spot through the WiFi module per se, the digital signals are transmitted to the digital equipment. The digital antenna enables the comprehensive program signals only disseminated by wireless signals to be excellently displayed on the portable digital equipment.

Description

technical field [0001] The present invention relates to the field of electronic radio, in particular, to an antenna. Background technique [0002] Antenna is a necessary equipment for electronic devices to realize wireless communication. Metal antennas are usually required for the transmission and reception of integrated program signals; generally speaking, under the same shape, the larger the size of the antenna, the better the transmission and reception performance. [0003] For the current digital devices, since most of them are portable devices, the bulky radio transceiver antennas cannot be installed on the digital devices; Micro-antenna for reception, the effect is poor, it is difficult to present exciting program content. Contents of the invention [0004] In view of the above problems, the object of the present invention is to provide a digital antenna, which can enable high-quality presentation of comprehensive program signals transmitted only by wireless signals...
