Abstract: A wideband antenna apparatus including a harmonically suppressed low band antenna is provided. The low band antenna is configured as a folded monopole antenna with patch coupling for resonance in a first frequency band. A patch portion of the low band antenna is widely separated from a folded feed portion of the low band antenna to avoid slot resonances above the first frequency band. The patch portion is relatively large to avoid folding of the patch portion that could introduce resonances above the first frequency band.

The high band antenna may be a folded monopole patch coupled antenna configured for resonating in a second frequency band. The high band antenna may optionally be configured like the low band antenna to suppress resonances of the high band antenna above the second frequency band.
