Abstract
An antenna includes a radiator that is electrically coupled to a feed stalk having a common-mode rejection (CMR) filter therein. The CMR filter is configured to suppress common mode radiation from the radiator by providing a frequency dependent impedance to a pair of common mode currents within the feed stalk, which is sufficient to increase a return loss associated with the pair of common mode currents to a level of greater than −6 dB across a frequency range including a frequency of the common mode radiation.
