A novel differentially driven dual-wideband double-layer complementary unidirectional antenna with a biorthogonal feeding structure for 2G/3G/LTE applications is proposed.
The proposed antenna is only around 9% of the bidirectional antenna in [13] and 21% of the unidirectional antenna in [6].
With MUOS, we're expected to have the capability to get to a unidirectional antenna with the solder in the foxhole."
Therefore, a novel design of dual-band magnetoelectric dipole unidirectional antenna for 2G/3G/LTE applications with low profile structure, high gains, easy fabrication, and low cost, is highly desirable.

This renders the omnidirectional antenna unsuitable for applications in the environment characterized by long and confined spaces in which a unidirectional antenna is more appropriate.
For the point-to-point connection topology, the unidirectional antenna is a promising candidate [10-12].
Different patch sizes have been examined within the 7-10 GHz range and a low-profile, wideband, unidirectional antenna has been realized by using the EBG.

To realize this goal, the traditional solution is to combine two circularly polarized unidirectional antennas back to back.
Due to the inherent balanced structure compared with the unbalanced antennas, such as dipole or loop antenna, the slot antenna has a potential advantage for low profile ultra-wideband unidirectional antennas. Therefore, a new cavity with two layer reflectors and an ABS attached to the vertical wall of the cavity is presented in this paper.
