Abstract
An impedance plane has an elongated strip ship. The impedance plane approximates a magnetic conductor within a particular frequency band. A sector antenna is coupled to one side of the impedance plane. The sector antenna has a planar form factor with dimensions contained within the elongated strip. The sector antenna has a radiation pattern in the particular frequency band that is flared out from the impedance plane at a particular angle.
