Problems solved by technology

The signal attenuation in the 60GHz frequency band is large, which is not suitable for long-distance transmission (Document 1, Ajung Kim, Young Hun Joo, and Yungsoo Kim. 60GHz Wireless Communication Systems with Radio-over-Fiber Links for Indoor Wireless LANs. Transactions on Consumer Electronics, 2004)
Therefore, how to use the EBG structure to improve the performance of dielectric resonator antennas in high-frequency systems is a challenge

Abstract

The invention provides a high-gain dielectric resonator antenna applied to a 60 GHz millimeter wave communication system, belongs to the technical field of electromagnetic propagation and receiving and provides a high-gain dielectric resonator antenna based on an H-shaped slot fractal uniplanar compact electromagnetic bandgap (HSF-UC-EBG) structure. The specific implementation is that a circle of HSF-UC-EBG structure is loaded around a radiating main body of a dielectric resonator antenna; and the high-gain dielectric resonator antenna is characterized in that the gain in a working frequency range of the antenna is effectively improved under the conditions of keeping size and section of the dielectric resonator antenna unchanged. The designed high-gain HSF-UC-EBG dielectric resonator antenna can be used in the 60 GHz millimeter wave communication system and provides guidance for designing a high-gain antenna which works in a high-frequency system.

Description

technical field [0001] The invention provides a high-gain dielectric resonator antenna applied to a 60GHz system, belonging to the technical field of electromagnetic transmission and reception. Background technique [0002] Broadband and wireless are two very important aspects of the main development trend of the communication industry. The 60GHz radio-over-fiber (ROF) communication technology has great application prospects because it meets the requirements of high-bandwidth wireless access. The 60GHz ROF system also has special requirements for the antenna. [0003] 1. Antenna in 60GHz system [0004] In the international 60GHz system, the bandwidth of the license-free frequency band is 9GHz, which is the frequency range of 57GHz-66GHz proposed by Europe. The signal attenuation in the 60GHz frequency band is large, and it is not suitable for long-distance transmission (Document 1, Ajung Kim, Young Hun Joo, and Yungsoo Kim. 60GHz Wireless Communication Systems with Radio-...
