This paper presents a sector-shaped microstrip patch antenna at an operating frequency of 1.4 GHz. In order to achieve wide beam and the normal radiation pattern, the radiation patch adopts sector. The shape of patch is the main factor affecting the performance of microstrip patch antenna. Besides, our feed network realized by electromagnetic coupling is achieved by a new method–T-shaped probe, which avoids the additional inductance introduced by the usual probe feed. Thus, the radiation efficiency of antenna is improved. In addition, the antenna has the characteristic of miniaturization. The electromagnetic simulation and optimization design of this proposed antenna are carried out using the CST Microwave Studio software package. The simulated VSWR of antenna is less than 1.5 at the working frequency. In this paper, we consider the microstrip antenna applying in some fields.
