Impedance Matching Problem

Impedance Matching Problem

(OP)
Hi everyone, need help here. I have designed a dual-band microstrip patch antenna for LTE and WiFi applications. The antenna operate at 2.6GHz for LTE and 5.0GHz for WiFi. I have started to design this dual-band antenna by designing the 5.0GHz WiFi antenna then introduce 2 inverted U slots to generate the resonant 2.6GHz. I cannot achieve impedance matching for the 2.6GHz LTE antenna. Please help and advice.

RE: Impedance Matching Problem

Impedance matching is used for eliminating power loss as the signal jumps from one circuit to the next. This is usually done by constructing RLC circuits with possibly a transformer. However, I think you might be having a problem with the difference between LTE and WiFi which I would guess is in the sidebands.
