Proposed within this document is a compact internal antenna intended for multiband operation. The antenna consists of two‐pronged elements with two stubs and has a comparatively small volume of 16 mm × 5 mm × 1 mm. The measured return loss of the designed antennas was >10 dB for wireless broadband (WiBro), wireless local area network (WLAN), world interoperability for microwave access (WiMAX), and satellite digital multimedia broadcast (S‐DMB) frequency bands. A high‐quality radiation pattern and a reasonable antenna efficiency were obtained within the desired frequency band.
