Embodiments of the present invention include antennas for transmitting and receiving electromagnetic signals. The antennas are configured to transmit a first electromagnetic signal at full power via a first set of radiating elements and to transmit the first electromagnetic signal at an attenuated power via a second set of radiating elements to decrease side lobes associated with the transmission of the first electromagnetic signal. The antennas are configured to receive a second electromagnetic signal having an associated first power level via the second set of radiating elements and to form an aggregated electromagnetic signal having a second power level that is a multiple of the first power level. The antennas are configured to attenuate the aggregated signal to form an attenuated electromagnetic signal having a third power level to facilitate uniform reception of the second electromagnetic signal and tapered transmission.
