Dual-band fan-beam array antenna for GSM900, DECT and 3G wireless applications

In this contribution, a fan-beam antenna employing a non-parasitic reflector in a grounded manner is introduced. A fan-beam antenna is achieved by 12 elements conventional planar triangular monopole array antenna. This concept is performed by combining planar monopole antenna as an array and non-parasitic reflector. The dual-band antenna is designed for 820-1050 MHz and 1700-2200 MHz input impedance matching bandwidth when simulated. The antenna has broad band input impedance band width, good radiation patterns, very good front to back ratio, good cross polar ratio and proper peak gains in GSM900, DECT, 3G, 4G bands. This type of antenna can be constructed easily, cheaply as well as being light weight for installation.
