Abstract
A low-profile, broad band monopole antenna (10) includes two linear radiators (11,13), a resistor network (18), and a transmission line network (20), all connected in series in that order. Linear radiator (11) includes a capacitor (12) which reduces the apparent electrical length of the antenna and provides high voltage isolation. Resistor network (18) reduces VSWR at lower frequencies in the band of interest such that in combination with the other elements, the VSWR for antenna (10) is sufficiently low that no further matching or tuning is necessary over the entire broad frequency band of interest without significant loss of gain relative to that of a monopole antenna one-quarter wave resonant at each frequency throughout the frequency band of interest.
