“…where Q L is the loaded quality factor, which quantifies the selectivity of a resonator and Q U is the unloaded quality factor which is the intrinsic electrical performance of a resonator. Q L and Q U can be calculated using two methods: using the reflection coefficient or the transmission coefficient as described in [13]. Using the first method and the design goals mentioned in Fig.…”

In this work, a simple and efficient approach to design a microstrip diplexer is proposed. It is based on the combination of two compact Square Open Loop Resonator band pass filters. These filters are designed for Radio Frequency Identification application at 2.45 GHz frequency. Using the Chebychev approximation, the two filters and diplexer are designed, simulated, fabricated, and measured. The results show that the diplexer presents a high selectivity, a good insertion loss and high isolation (>40 dB) with the compact size. The diplexer also shows a good performance when associated with the patch antenna operating at 2.45 GHz.

“…Line-coupled filters [10][11][12] have been used since 1958 for their ease of initial design and technological realization for integrated circuits, but their larger size limits their integration with the new generations of intelligent electronic systems. In this context, several researchers have proposed more efficient and easy methods compared to coupled lines technique for designing microwave filters of miniaturized size [13][14][15][16][17][18][19].…”

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.
