1. An antenna device, comprising:
- a first elliptic reflective surface having a first focus and a second focus;
a first antenna disposed on the first focus for transmitting a first signal and a second signal; and
a second antenna disposed on the second focus for receiving the first signal and the second signal, wherein the first signal is directly transmitted from the first antenna to the second antenna, and the second signal is reflected by the first elliptic reflective surface and transmitted to the second antenna.

Abstract
An antenna device includes a first elliptic reflective surface, a first antenna and a second antenna. The first elliptic reflective surface has a first focus and a second focus. The first antenna is disposed on the first focus, and the second antenna is disposed on the second focus. The first antenna transmits a first signal and a second signal, and the second antenna receives the first signal and the second signal. The first signal is transmitted directly to the second antenna from the first antenna. The second signal is reflected by the first elliptic reflective surface and transmitted to the second antenna.

17. An antenna device, comprising:
-
a plurality of elliptic reflective surfaces, wherein each of the elliptic reflective surfaces has two foci and one of the foci coincides with one focus of one adjacent elliptic reflective surface; a plurality of transmitting antennas disposed on one part of the foci for respectively transmitting a first signal and a second signal; and a plurality of receiving antennas disposed on the other part of the foci for respectively receiving at least one of the first signals and at least one of the second signals, wherein the first signal is directly transmitted from the transmitting antenna to the receiving antenna, and the second signal is reflected by the elliptic reflective surface to the receiving antenna. - View Dependent Claims (18, 19, 20, 21)
