“…However, both of them have high frequency ratios, while in [7] the bandpass channel is narrow. Some designers obtained negative group delays out of −3 dB passband frequencies [12, 13]. A negative group delay does not break causality [13].…”

This paper presents the design of a novel lowpass–bandpass diplexer with compact size and good performance using microstrip cells. For this purpose, two microstrip lowpass and bandpass filters are separately designed and mathematically analyzed. The proposed microstrip diplexer has a novel and simple structure. It occupies a compact area of 0.037 λg2 (722 mm2), and its insertion loss and S11 at both channels are low. The insertion loss at the lower and upper channels is only 0.047 and 0.16 dB, respectively. Meanwhile, both channels are flat with the maximum group delay of 1.68 ns which is the lowest compared to the previously reported diplexers mentioned in this paper. To design the proposed diplexer, first, a lowpass diplexer with good performance is designed which has low losses and a good figure of merit. It has a flat passband with a sharp roll-off. Then, to achieve the proposed diplexer, a bandpass resonator is added to the lowpass filter without any extra matching circuit, which saves the overall size. The proposed diplexer is designed, simulated, and fabricated, where the simulation and measurement results are close.

“…Designing compact diplexers with good performance is important for the wireless networks industry. Several types of lowpass-bandpass diplexers [1][2][3][4][5][6][7][8] and bandpass-bandpass diplexers [9][10][11][12][13][14][15] have been reported. Designing lowpass-bandpass diplexers is less common than the bandpass-bandpass diplexers.…”

“…The results demonstrate that despite its small size, the diplexer offers excellent selectivity, the insertion loss is low, and low high isolation. In article [26], the researchers have a definition for diplexers, which are dual-filter circuits with three ports, that allow for the simultaneous use of an antenna by two separate frequency channels. However, this tech can be used with several transmitters operating at different frequencies as long as each band is used for sending and receiving signals.…”

“…Printed microstrip patch antennas, such as FR4 and Roger. As a result of its compact, low profile configuration and ease of integration with microwave circuits [10,11]. It is therefore suitable for wireless communication systems, cellular phones, radar systems, and satellite communication systems [12][13][14][15].…”
