摘要： A receiver of a frequency modulation (FM) system includes a first dielectric substrate, a second dielectric substrate, a helix antenna and an FM module. The helix antenna is formed between the first dielectric substrate and the second dielectric substrate and has a first end and a second end opposite to the first end. Thereby, a central axis of the helix antenna is approximately parallel to a side of the first dielectric substrate. The FM module is formed on the first dielectric substrate and electronically connected to the first end of the helix antenna. Besides, the FM module is used for transforming high-frequency signals received by the helix antenna into intermediate-frequency signals.
