A kind of electronic equipment comprises:
Device housings 10;
Unipole antenna 20, be arranged in device housings 10, unipole antenna 20 comprises first paragraph 201, and is bent by first paragraph 201 and extend and the second segment 202 that formed, first paragraph 201 and second segment 202 substantially L-shaped; Comprise the unipole antenna first end 2011 being positioned at first paragraph 201 and unipole antenna second end 2021 being positioned at second segment 202; Unipole antenna second end 2021 is feed port.

Specifically, in the embodiment of the present application, coaxial cable 30 passes through unipole antenna second end 2021 to unipole antenna 20 feed by the mode directly connected.Owing to being encouraged, unipole antenna 20 forms a high-frequency resonant electromagnetic field at first paragraph 201 place, i.e. the high-frequency resonant electromagnetic field of described first coverage.Reach Energy Coupling state by the resonant energy of unipole antenna 20 first paragraph 201 with the loop aerial 40 being positioned at described first coverage, thus form the excitation to loop aerial 40, excite loop aerial 40 further.Thus reaching a port feed, the antenna of unipole antenna and loop aerial two kinds of different shapes encourages simultaneously and forms the technique effect of radiation.
Because loop aerial 40 forms excitation by unipole antenna 20 coupling energy, its first end 4011 and the second end 4021 all ground connection, namely himself be two short-circuit resonant unit, therefore there is a radiant section in the middle part of loop aerial 40,, then there is zero radiant section respectively in direction of both ends zero potential place.

Mode two, as shown in Figure 2 B, the first end 2011 of unipole antenna 20 is positioned at the region exterior that loop aerial 40 surrounds.
In order to realize unipole antenna 20 and the loop aerial 40 energized design forming radiation simultaneously, position relationship between unipole antenna 20 and loop aerial 40 can be: have angle between the first paragraph 201 of radiant section 403 and unipole antenna 20 α, angle α is an angle within the scope of a predetermined angle, in the embodiment of the present application, predetermined angle scope is specifically as follows 0 ° to 15 °; When angle α is within the scope of described predetermined angle, loop aerial 40 is positioned at described first coverage.
Due to, unipole antenna 20 end, namely first end 2011 is when resonance, can by Energy Coupling on loop aerial 40, therefore unipole antenna 20 and the relative position of loop aerial 40 must meet the needs of end Energy Coupling, can not exceed the ultimate range that can realize required for coupling.In the embodiment of the present application, two kinds of execution modes can specifically be had.
Mode one, as shown in Figure 3A, the first paragraph 201 of unipole antenna 20 is positioned at the plane at loop aerial 40 place.Now, the first end 2011 of unipole antenna 20 is positioned at the plane that loop aerial 40 is formed.
