Planar antenna oscillator

The utility model discloses a planar antenna oscillator. The antenna comprises a square feed connecting plate located in the center, two first radiation assemblies and two second radiation assemblies.The two first radiation assemblies are oppositely arranged on the two sides of the feed connecting plate. Wherein the two second radiation assemblies are oppositely arranged on two sides of the feedconnecting plate, the first radiation assembly comprises two first radiation arms which are symmetrically arranged, each first radiation arm comprises a first connecting plate and a first radiation plate which are connected in sequence, and the two first radiation plates of the two first radiation arms are arranged along the same straight line; the second radiation assembly comprises two second radiation arms which are symmetrically arranged. Each second radiation arm comprises a second connecting plate, a second radiation plate and a coupling arm which are connected in sequence. The base station antenna is reasonable
