The self-curing decoupling concept is applied to two coupled Inverted-F antennas (IFA) working in adjacent bands. The interference in the guard band of two wireless systems working in two adjacent frequency bands can be easily reduced by a capacitive load on the shorting arm of each IFA antenna. This decoupling technique is simple to implement in practical applications and occupies almost no extra space. A network analysis is presented to justify the decoupling concept and to provide a design guideline. To verify the effectiveness of the technique, a typical scenario of the coexistence of two IFA antennas working for LTE band 40 (2300 MHz–2400 MHz) and IEEE 802.11b (2400 MHz–2483.5 MHz) is studied. The isolation improvement from 10 dB to 20 dB in the adjacent bands by using this self-curing decoupling technique can be achieved.
