摘要： A dual band antenna for a radio terminal consists of a retractable whip antenna and a helical antenna with irregular pitches, wherein the whip antenna is independent of the helical antenna. The helical antenna includes first and second helical portions having first and second pitches, respectively and the first and second helical portions are operable at different frequency bands independently. The whip antenna includes a conductive core line, a conductive substance covering a first portion of the conductive core line to serve as a choke and an isolation element extending from an upper end of the conductive core line, for filling a gap between the conductive core line and the conductive substance. Here, only the first portion of the conductive core line is operable at a first frequency band and the entire conductive core line is operable at a second frequency. A fixing element fixes the helical antenna and the whip antenna to the radio terminal. The fixing element has an upper end connected to a lower end of the helical antenna and a through hold via which the whip antenna is inserted into an interior of the radio terminal.

摘要： A dual band antenna with a simple and compact structure includes an inductor, first and second rod-like radiating elements connected to opposite ends of the inductor, with dielectric material surrounding both the inductor and the joining portions of the first and second radiating elements on the respective ends of the inductor. A conductive housing surrounds the dielectric and supports the inductor and the joining portions of the first and second radiating elements. The housing and dielectric create a capacitance, so that an LC resonant circuit is formed in conjunction with the inductor. The LC circuit is designed such that only one radiating element radiates at the higher band of the dual operating band, whereas both radiating elements radiate at the lower band.

摘要： A dual band antenna for mobile communications includes a rod-shaped radiating element having a first portion of a predetermined length connected to a coaxial feed line, and a second portion of a specified length integrally extended from the first portion. The coaxial feed line connects to a ground plate, and a first capacitive load connects to the first portion of the radiating element. A choke surrounds the second portion of the radiating element, and has a shorting end connected to a distal end of the second portion and an open end at a proximal end of the second portion. A second capacitive load connects to the shorting end of the choke. In a higher operating band of the dual band, the input impedance of the choke is high, such that only the first (lower) portion of the radiating element radiates. At a lower operating band of the dual band, the choke's input impedance is lower to allow for radiation from the entire length of the antenna.
