    摘要: Antenna systems (200, 1300, 1500, 1900, 2000, 2400) comprise a dielectric resonator antenna (210) in the shape of a parallelepiped with right angle corners. The thickness (T) of the dielectric resonator antenna (210) is chosen to be less than the length and height. The antenna systems (200, 1300, 1500, 1900, 2000, 2400) provide have broad band response that is attributed to two or more resonant modes that have center frequencies that are closely spaced in frequency relative to their bandwidths. Additional pass bands can be obtained by placing a conductive strip (1302) along an edge of the dielectric resonator 210. The passband associated with the conductive strip (1302) can be lowered in frequency by capacitively loading the conductive strip (1302). An additional passband can also be obtained by coupling a metal ribbon (2012) to a feed in microstrip (206, 2002) and to the dielectric resonator antenna (210).

    摘要: To address the above-mentioned need an antenna (100) is provided having a conductive-strip radiating element (102) supported above a substrate (206) via three legs (201-203). The point where the substrate contacts the three legs form two antenna ports and a ground utilized for feeding the RF signal, tuning the antenna, and grounding. More particularly, a first leg (201) of the radiating element is used solely as a tuning port, while a second leg (202) is grounded, and a third leg (203) is utilized solely as a feed port. The tuning port is substantially maximally distal to the feed port on the substrate. Reactive loads are provided at the tuning port to effectively tune the central operating frequency of the antenna.
