Abstract:

Abstract: High performance structure technology, miniaturization and multi-band methods of internal antenna were investigated. The main research orientations and application characteristics of internal antenna in recent years were summarized. The key technology in the design of high performance internal antennas of mobile terminals such as antenna structured method, combinatorial method, bandwidth enhancement, and loaded method were investigated and analyzed. Meanwhile, based on the practices of actual internal antenna production, we discussed the difficulties in miniaturized, multiband and high performance internal antennas and provided some effective solutions. The research indicated that the advanced manufacturing technology has promoted the implementation of the 2-3 bands internal antenna, however, the implementation of three or more bands should mainly depend on the combinatorial method. Predictably, the new technology of internal antenna is coming to the fore which will promote wider application of mobile terminals and meet the future demand for development of seamless, ubiquitous mobile radio communication network.

Key words: internal antenna, multiband, miniaturization
