Abstract
The invention discloses a broadband dual-polarization side-emitting slot coupling patch antenna applied to a mobile terminal. The antenna is composed of a first layer substrate (11a), a second layer substrate (11b), a third layer substrate (11c) and a fourth layer substrate (11d) which are sequentially arranged from bottom to top. A first bonding layer (11e) is arranged between the first layer substrate (11a) and the second layer substrate (11b); a second bonding layer (11f) is arranged between the second-layer substrate (11b) and the third-layer substrate (11c); a third bonding layer (11g) isarranged between the third layer substrate (11c) and the fourth layer substrate (11d), the size of the antenna is 0.4 lambda 0 * 0.4 lambda 0, the total thickness is 0.15 lambda 0, and lambda 0 is the free space wavelength at 27 GHz. The antenna can realize high-isolation dual-polarization side emission in a wide frequency band. The antennas form a 1 * 4 linear array, the high-gain multi-beam performance of the antenna array is achieved through a 3-bit phase shifter, and the scanning angle reaches + / -45 degrees.
Description
