Antibodies normally diminish after the specific pathogen is cleared. There's no point in your body continuing to waste resources on something that is no longer a threat. However, during the immune response, your body created "memory B Cells" which contain the template for the effective anitbodies. They are responsible for the rapid immune response that confers immunity. They can last for decades. Note that these are different than memory T cells, which work along a different , but intertwined, pathway.
