A broadband, compact, omnidirectional antenna (10) usable in the 800-1000 MHz frequency range incorporates an elongated, symmetrical, radiating stud (26) which terminates in a cylindrical metallic radiating cap (22). A cylindrical, non-conductive hollow housing (32) with first and second ends (30a, 30b) surrounds the stud and is closed at one end by the radiating cap. Over all, the length of the antenna is less than a corresponding quarter wave monopole while providing better performance characteristics, and, greater structural stability then metal or whip-type antennas. |
