Lumped element filters using capacitors and inductors are unrealistic for compact designs of wireless communications equipment, especially hand-held devices. Distributed element filter design offers a much smaller area and are low profile. With the initiation of advanced substrate materials offering high dielectric constants with low loss, the size reduction with preserved efficiency is greatly enhanced. Transmission line filters can be easy to fabricate, depending on the type of transmission line used. This paper proposes the microstrip line stepped impedance low pass filter. This paper presents about the design, testing and fabrication of microwave low pass filter by using micro strip layout. The development of the micro strip filter is simulated by using CST2019 software followed by practical measurements using R&S make Vector Network Analyzer. The higher cutoff frequency is 2.4GHz and has insertion loss is-23dB at 3.9GHz.
Design and Analysis of Microstrip Low Pass and Bandstop Filters
Regular Issue, 2019
In this paper a simple approach of designing the microstrip low pass and bandstop filter is presented. The microstrip stub based low pass filter with 2.4 GHz and attenuation of more than 60 dB at 4 GHz frequency is designed. The bandstop filter is also designed with notch characteristics at 2.4 GHz frequency. The fractional bandwidth of designed filter is estimated to be 30% with 117 dB of attenuation is recorded at notch frequency of 2.4 GHz in SIR based bandstop filter topology. The bandstop filter is implemented using coupled line structure as well as step impedance resonator techniques. The filters are designed on Roger RC40003C substrate. The design and analysis of filter with its layout and EM simulation is accomplished using Agilent ADS software. These filters can be used in front end transceiver systems, antennas, and modern wireless communication systems.
Compact Low Pass Filter Design for L-Band Application
Journal of Electromagnetic Analysis and Applications, 2011
An effective technique to design compact low pass filter has been proposed in this paper. The proposed method is highly effective for L-band applications. Low impedance microstrip lines are arranged such that they work as open stubs to increase the selectivity of the filter. Using the proposed technique about 57% size reduction has been realized with sharper roll off characteristics. An empirical expression is derived to determine the dimension of resonators. For cutoff frequency of 1.7 GHz the investigated method has been fabricated and tested. There is a close agreement between simulated and measured results.

DESIGN OF STEPPED IMPEDANCE LOW PASS FILTER AT 2.4GHz
In this era, life can't be envisioned without wireless communication. The microwave filter is a component which gives frequency selectivity in mobile, radar, satellite communication systems working at microwave frequency. Microwave low pass filter attenuates the unwanted signal above cut off frequency. For stepped impedance filter design high and low impedance lines are used. This paper describes designing of Chebyshev approximated stepped impedance low pass filter at 2.4 GHz with the permittivity of value 4.2 and the height/thickness of the substrate is 1.6mm for the order n=3. Designed filter is simulated using Computer Simulation Technology.
Development of Microstrip Filter for Telecommunication Application
2019
The advances of telecommunication technology arising hand in hand with the market demands and governmental regulations push the invention and development of new applications in wireless communication. These new applications offer certain features in telecommunication services that in turn offer three important items to the customers. The first is the coverage, meaning each customer must be supported with a minimal signal level of electromagnetic waves, the second is capacity that means the customer must have sufficient data rate for uploading and downloading of data, and the last is the quality of services (QoS) which guarantee the quality of the transmission of data from the transmitter to the receiver with no error. In order to provide additional transmission capacity, a strategy would be to open certain frequency regions for new applications or systems. In realization of such a system like WiMAX we need a complete new transmitter and receiver. A band pass filter is an important c...
