The one centre point connection of line, the outer conductor of feed connection is connected with another parallel strips of symmetrical printing.
Preferably, the metal radiation oscillator is strip, and its size is the quarter-wave of antenna low frequency operating frequency.
Preferably, the dielectric-slab can be solid dielectric or air dielectric.
Preferably, the relative distance of the parallelogram metal patch and metal radiation oscillator, relative distance in short-term, increases
Plus the coupling of energy so that the impedance bandwidth of antenna is big, and its relative distance determines according to the requirement of the impedance bandwidth of antenna.
Preferably, the metallic reflection oscillator, its width size influences the front and rear than size, rectangular metal reflection of antenna
When the width of oscillator is bigger, the front and rear ratio of antenna increases.The width of rectangular metal reflection oscillator is required according to the front and rear ratio of antenna
It is determined that.
Preferably, the broadband parallelogram antenna, metallic reflection oscillator it is relative with metal parallel strips lower end away from
Determine from by the size of feed point SMA.
Preferably, the size of parallelogram metal patch is the quarter-wave of the higher operational frequency of antenna.
Compared with prior art, the beneficial effect of technical solution of the present invention is：
