Design of a Microstrip Slot Dipole-Antenna

In this paper, a microstrip slot dipole-antenna has been designed, which is feeding by the coupled microstrip line. Through slotting on both side of the radiation patches, the symmetrical H- type dipole antenna is designed to realizing dual-peak resonance. The working bandwidth has been wide and the radiant gain has been enhanced by increasing current effective path. Through the simulation and optimization of the designed antenna, the microstrip antenna forms a dual-frequency resonance at 4.3GHz and 5.6GHz, and the impedance bandwidth with VSWR less than 2 reaches 0.7GHz. The designed antenna is only 30$\times$ 15mm2, which is conducive to the miniaturization and integration of communication equipment.
