Abstract

A new type of antenna, which is suitable for 2G/3G/4G communication network, is put forward in this paper. The designed antenna is constructed by the four parts of dielectric substrate, reference ground, micro-strip feeder line and the radiating element. The working frequencies cover altogether 25 bands of the 2G/3G/4G communication network in China Mobile, China Unicom, China Telecom and WLAN 2.4 GHz (2.405GHz-2.485GHz). It meets the need of multi-band frequency in 2G/3G/4G mobile phone communication. Meanwhile, the antenna enjoys the advantages of light weight, small size, low profile, simple for manufacture and low cost, which allows a broad application prospect and satisfies the requirement of modern mobile phone communication completely.
