This paper presents a simple structure of dual-band filtering antenna for wireless application. The antenna is treated as radiating resonator. The filter of synthesis theory is applied to the design of the dual band filtering antenna. The theory can help us the guidance of processing design. The proposed dual band filtering antenna has simple structure and display excellent performance. The dual band filtering antenna presents characteristic of three order filter with high selectivity of pass-band and strong suppression of stop-band. The measured results show approximately agreement with the simulations.

“…In the advancement of the modern communication framework, today the scaling down of the microwave diplexers and enhancing the performance parameters turns out to be more critical and tough challenge [4–11]. The wireless communication system with the blend of WiMAX (IEEE 802.16 standard, operating at 3.3–3.9 GHz with a bandwidth of 600 MHz) and WLAN (IEEE 802.11 standard operating at 5.15–5.85 GHz with a bandwidth of 700 MHz) are in mainstream these days [3].…”

In this paper, design and development of a via-free composite right/left handed transmission line (CRLH TL)-based diplexer for WiMAX and WLAN bands is reported. The diplexer is having two channels, where each channel consists of a separate bandpass filter (BPF). The BPF of both channels are designed on via-free CRLH TLs based on a newly proposed right-angled corner-modified split ring resonator (RAC-MSRR) structure. The RAC-MSRR incorporates meander paths because of which working scope of frequencies is focused for measured center frequencies (f1) 3.5 GHz with −3 dB fractional bandwidth (FBW) of 21.21% (BPF1 channel) and (f2) 5.6 GHz with −3 dB FBW of 13.29% (BPF2 channel). For diplexer design, T-section is used for joining two BPFs which results in very good isolation of more than 32.5 dB over the frequency band of 2.5–8.0 GHz. The designed diplexer has passband insertion loss of −0.87 dB at f1 and −1.25 dB at f2. Overall size of the fabricated diplexer including 50 Ω feed line is 18 × 15 mm2. Equivalent lumped circuit model parameters of the diplexer are obtained from the pseudo-inverse matrix technique. Measured results show good concurrence with simulated results and subsequently approve the proposed model design.

“…From the literatures, several examples can be found in certain designs such as antenna [3][4][5][6], filter [7][8][9], switch [10][11][12], mixer [13] and low noise amplifier [14], [15]. Besides, the demand has also led to the challenge in RF and microwave circuit design to support the requirements of different frequency bandwidths for different bands.…”

In this paper, a design of hybrid microstrip diplexer is proposed for multiband Worldwide Interoperability for Microwave Access (WiMAX) application in 2.3 and 3.5 GHz bands. The diplexer consists of a combination of two different filter designs. These filters were designed based on microstripline coupling techniques in order to obtain minimum insertion losses and achieve the desired frequency bandwidth. Therefore, a coupled open loop ring resonator was chosen for the filter design in 2.3 GHz band and a folded coupled line resonator was chosen for the filter design in 3.5 GHz band. Then, these filters were combined with a ring manifold matching network to be a hybrid microstrip diplexer. Based on the results, good agreements were achieved between the simulation and measurement results in terms of insertion loss, return loss and bandwidth in the 2.3 and 3.5 GHz bands.
