Abstract
The coupling mechanism of the twin slots fed by the conductor-backed coplanar waveguide is investigated. The goal is to improve the antenna efficiency by using the phase cancellation technique and at the same time keep the structure as simple as possible. The leakage phenomenon is illustrated visually and the effects of the antenna parameters are examined numerically for choosing the appropriate variables. Finally the proposed antenna is fabricated and tested, showing 69.8% of antenna efficiency.
