Antenna for wireless device

摘要

An antenna for a wireless device includes a low band left-handed (LBLH) mode element and a low band right-handed (LBRH) mode element both operable in a low frequency bandwidth and a high band left-handed (HBLH) mode element and a high band right-handed (HBRH) mode element both operable in a high frequency bandwidth. The LBLH mode element is capacitively coupled to a feed of the antenna and is inductively coupled to a ground of the antenna. The LBRH mode element is electrically coupled to the feed of the antenna. The HBLH mode element is capacitively coupled to the feed of the antenna and is inductively coupled to the ground of the antenna. The HBRH mode element is electrically coupled to the feed of the antenna. At least one tuning element is operatively coupled to at least one of the mode elements.

1. An antenna for a wireless device, the antenna comprising:
a low band left-handed (LBLH) mode element operable in a low frequency bandwidth, the LBLH mode element being capacitively coupled directly to a feed line of the antenna and being inductively coupled to a ground of the antenna; a low band right-handed (LBRH) mode element operable in a low frequency bandwidth, the LBRH mode element being conductively coupled to the feed of the antenna; a high band left-handed (HBLH) mode element operable in a high frequency bandwidth, the HBLH mode element being capacitively coupled directly to the feed line of the antenna and being inductively coupled to the ground of the antenna; a high band right-handed (HBRH) mode element operable in a high frequency bandwidth, the HBRH mode element defined by at least a portion of the feed line of the antenna; and at least one tuning element being operatively coupled to at least one of the mode elements.
