A collapsible interior antenna has a main antenna, two wing antenna assemblies and a secondary antenna. The main antenna is rectangular and has two opposite connecting edges. The wing antenna assemblies are pivotally mounted respectively on the connecting edges and connected transmittably to the main antenna. The secondary antenna is a telescopic antenna, receives signals having a different frequency band to the main antenna and is electrically mounted on the main antenna. A person can minimize a footprint of the collapsible interior antenna by retracting the secondary antenna and folding the wing antenna assemblies toward the main antenna. When in use, the wing antenna assemblies can be unfolded to receive signals from different directions.
