Abstract
This antenna array includes at least one primary antenna, at least one secondary antenna and at least one load coupled to a secondary antenna. The load includes two separate components, a first component being a resistor and a second component being selected from an inductor or a capacitor. The antenna array can include one or more of the following characteristic features, taken into consideration individually or in accordance with any technically possible combinations: the first component has negative resistance; the second component has negative inductance or a negative capacitance; at least one load has an adjustable impedance. The antenna array may be used in a system, such as a vehicle, a terminal, a mobile telephone, a wireless network access point, a base station, or a radio frequency excitation probe.
