Notice: As of 2014 and for the forthcoming years, the publication frequency/periodicity of WSEAS Journals is adapted to the 'continuously updated' model. What this means is that instead of being separated into issues, new papers will be added on a continuous basis, allowing a more regular flow and shorter publication times. The papers will appear in reverse order, therefore the most recent one will be on top.

ABSTRACT: The recent development in wireless communication demands the wireless devices to operate between multiple communication bands. The most important RF module which is supporting the communication band separation between wireless devices is a Filter. The design challenges of any filter circuits are performance, cost and size. In this paper an open circuited stub based method is selected to realize a multiband band pass filter for GSM (1.8 GHZ), UMTS (2.1 GHz), ISM (2.4 GHz), WiMax (3.5 GHz) and LTE Band 3 (1.8 GHz) applications. The concept of defected ground structure is also applied to improve the performance of the filter. The simulated and measured parameters of the proposed filter are presented.

KEYWORDS: Transmission zero (TZ), Defected Ground Structure (DGS), and Band Pass Filter (BPF), Wireless communication, microstrip, insertion loss.
