“…So, more efforts have been made for reducing the size of the microwave components and devices, focusing especially on filters [2,3]. With the increasing demands towards miniaturization of size and for enhancing the performance of filters circuits, innovative techniques of making compact size microwave components and devices are used with the better performance [4][5][6][7]. The realization of these microwave filters is directly related to the properties of the technology, which is used.…”

In wireless communications systems, the microstrip filter has an important job in terms of selectivity and elimination of the undesired signals. Microstrip filters are always preferred over the lumped filters at a larger frequency for their compact size, lighter weight, lower cost, and higher performance. In this paper, the design, optimization, and realization of a compact narrow-band bandpass filter using two identical square open-loop resonators is presented for a frequency of 2.4 GHz.This filter is printed on a RO6010 substrate with a dielectric constant of 10.2, a thickness of 1.27 mm and a tangent loss of 0.0023. The proposed filter is intended for wireless communications systems such as (RFID, Wi-Fi, Bluetooth, and WLAN) and medical applications systems that operate at the resonance frequency of 2.4 GHz. This bandpass filter has very high selectivity in the bandwidth of 290 MHz, the small size of (9.4 × 23.1) mm 2 , and small insertion loss of -0.23 dB. The proposed filter structure is easy to fabricate and the achieved results are very encouraging.

“…The difference between these two types of resonator is, ring resonator have the advantage in term of their ring structure that deliver low passband insertion loss and higher quality factor (Q-factor) [4]. Others attractive features of ring resonator such as low radiation loss, high Q-factor, compact size, dual-mode capabilities and sharp rejection skirts [5] [6] [7] [8] make their popularity increased for bandpass filter applications. The usage of microwave and RF filters are widey used in all the communication technologies and electronic system in order to differentiate between any wanted and unwanted signal frequencies band for filtering process [9] [10].…”

An output coupled line wavelength ring resonator centered at 3 GHz operating frequency for bandpass filter application is presented in this paper. The proposed ring resonator demonstrates a single mode resonant frequency at 3 GHz with a pair of transmission zeroes.This ring resonator consists of even and odd mode line impedance, and coupled to the output feed lines along a quarter-wavelength of its side to generate a single-mode bandpass response with two transmission zeroes at 2 GHz and 3.5 GHz. The design of the resonator filter is simulated in Microwave Office (AWR Design Environment) based on the design specification and fabricated on Flame Retardant Type-4 (FR4) microstrip substrate with dielectric constant, ε r =4 and height of thickness, H = 4 mm. All the simulation and measurement results are presented and discussed in this paper to show its feasibility.
