20120169556 | BROADBAND MULTI-FREQUENCY MONOPOLE FOR MULTI-BAND WIRELESS RADIO - A top load multi-band monopole antenna is utilized with an integrated resonator to achieving broad band and multiband performance for multiple frequency spectrums. The top loaded monopole antenna can utilize a low frequency band (e.g., approximately 700/800/900 MHz) and a high frequency band (e.g., approximately 1900 MHz to approximately 1500 MHz) by implementation of the resonator. The resonator matches an impedance of the upper portion of the top loaded monopole antenna for capabilities in a high frequency range without interference from any low frequency range. | 07-05-2012 |
