TY - JOUR A1 - Sánchez Hernández, David Agapito T1 - Dual band printed antenna Y1 - 2009 UR - http://hdl.handle.net/10317/1061 AB - The antenna has a dielectric substrate layer whose front side presents a patch antenna fed by a microstrip line stretch and whose back side presents an Earth reference. This patch has the shape of an isosceles triangle which connects one vertex to the stretch, while in parallel to the opposite side of the vertex, there is a slot in the patch operating like a filter. This enables a dual band operation wherein two resonant frequencies are controlled by the variation of the patch size and the slot length. The frequencies can be adjusted to values of 900 and 1800 MHz, facilitating the application of the antenna in dual mobile telephony with GSM and DCS-1800 systems. With this technological offer we try to collaborate with licence agreement and commercial agreement with technical assistance.
