Abstract
Broadband slot-coupled stacked patch antenna elements are capable of continuous broadband operation between 1.71 GHz and 2.69 GHz. The broadband slot-coupled stacked patch antenna element includes a mid-band radiating patch, a high-band radiating patch, and a low-band resonator with coupling slots capable of resonating at low, mid, and high band frequencies. Additionally, a low-profile probe-fed patch element is provided for pattern enhancement of antenna arrays at high-band frequencies. This low-profile patch element features fan-shaped probes that have three degrees of tune-ability, namely a length, a width, and a spreading angle. Further aspects include 3-column and 4-column offset arrays of the broadband patch radiators and an interleaved array of the low-profile high-band patch radiators and the broadband radiating elements. A new type of azimuth beam forming network (ABFN) is also introduced for the beam forming of the 3-column and 4-column dual-beam arrays.
