Abstract
A dual band antenna structure is disclosed. The dual band antenna structure utilizes features from loop ground edge radiating antennas and inverted-F antennas to create an antenna that has two resonance frequencies. The dual band antenna structure includes a loop ground edge radiating antenna, which has a first resonance frequency. A monopole branch is also located at the end of the feeding trace to provide a second resonance frequency. The dual band antenna structure is useful for network devices that operate at multiple frequencies, such as those using the WiFi/BLE/IEEE802.15.4 protocols.
