Abstract

Abstract:

According to the theory of electromagnetic field, this paper presents a design method of a microstrip patch antenna for wireless communication. According to the working frequency band of the antenna, the antenna structure is designed and the equivalent circuit is analyzed. In order to verify the effectiveness of the antenna structure parameters, finite element simulation, the antenna structure parameters optimization to achieve an optimal bandwidth and radiation to the actual production and test results show that the impedance bandwidth of the antenna (10dB return loss) is up to 10GHz(2.0～12.0GHz), and that the absolute bandwidth of the multiplier is up to 6, the bandwidth being three times the cross bandwidth of the monopole antenna. In addition, the antenna has a good omnidirectional radiation characteristics and gain level in the operating frequency, and the antenna has a simple structure, a stable performance and good practicability.

Key words: patch antenna, broadband, omnidirectional, gain
