Abstract

The invention discloses a rectangular microstrip antenna working in a higher-order mode in mobile applications, belongs to the technical field of wireless communication, and aims to provide a method for producing an omni-directional conical beam pattern (OCBP) by utilizing a mode TM02 and a mode TM20 of the rectangular microstrip antenna. The rectangular microstrip antenna comprises a cylindrical medium substrate, an irradiator arranged on the front face of the medium substrate, an earth plate arranged on the back face of the medium substrate and two coaxial probes carrying out feed on the antenna. The rectangular microstrip antenna appropriately selects the mode TM02 or the mode TM20 through dual-port equiamplitude in-phase current excitation and annular gaps, and achieves high isolation and good impedance matching for the two ports. The rectangular microstrip antenna working in the higher-order mode in the mobile applications guarantees a simple antenna form and a simple feed structure while achieving expected targets, and has quite high use value and broad application prospects.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a 02 and TM 20 pattern omnidirectional radiating rectangular microstrip antenna. Background technique [0002] With the rapid development of modern information technology, mobile communication technology has penetrated more and more into people's daily life. As a key component in the mobile communication system, the quality of the antenna (transmitting / receiving) directly affects the communication quality. Therefore, an antenna with excellent performance is particularly important for the improvement of mobile communication quality and technological progress. Since the 1970s, the microstrip antenna was first developed by researchers, and it has been concerned and favored by all parties due to its light weight, small size, low cost, planar structure, and compatibility with integrated circuits. However, the design of an omnidirectional radiation micros...
