“…However, they have the same resonant frequencies. The proposed filters are 3rd order Chebyshev Tx, and Rx filters with a high roll-off compared to that in literature [28][29][30][31][32][33][34] which have at least similar order or higher. The filters exhibit narrow fractional bandwidth of 0.0444, and 0.0337, respectively compared to those in literature [28][29][30][31][32][33][34].…”

In the past decade, the majority of the launched satellites have a weight exceeds 1 Ton. Its development takes a long time, high cost, and has a large risk of failure, and does not allow for testing new technologies to avoid the mission's failure. From these points of view, space-tested technologies were preferred to mitigate the risk of failure. Our goal is to build and test our own S-band communication subsystem for CubeSat. The system should be developed with reliable and compact hardware and flexible and efficient software. It consists of passive components such as the antennas and the filters and other active components. The passive components are designed, fabricated and measured while the active components are based on commercial components. In this paper, two antenna boards are designed; one board faces the earth and the other board lies on the opposite side. Each board has two antennas; transmitter and receiver antennas. The transmitter/receiver antennas are operating in the downlink /uplink at frequency bands from 2.2 GHz to 2.29 GHz and from 2.025 GHz to 2.11 GHz, respectively. This configuration keeps the communication between the CubeSat and the ground station to facilitate the de-tumbling process of the CubeSat. The second component is the filters that separate the transmitter from the receiver. The two filters have high roll off and narrow fractional bandwidth within a compact area. The transceiver system is based on the analog devices chip AD9361 controlled by zynq-7000 FPGA. The output RF signal is amplified to approach 33dBm output power to the antenna port via QORVO chip that operates in the range from 700MHz to 2700MHz. The antennas and filters are fabricated and tested where good results are noticed so that they are ready for integrating with the whole CubeSat communication subsystem.

“…Waveguide and printed filters are known as the most common technologies, with their advantages and disadvantages well-discussed 1 . Several technologies, such as low temperature co-fired ceramic (LTCC) [2][3][4] ,microstrips [5][6][7] , waveguides 8,9 , and micro-electromechanical systems (MEMS) 10,11 , are used to develop bandpass filters with specific characteristics such as low cost, high selectivity, low insertion loss, broad bandwidth, compact size, and power handeling capacity. Due to the trade-off between these parameters, sometimes we have to prioritize a number of characteristics that are more important for our design.…”

Integration of planar circuits been considered a credible technique for low-cost mass production of microwave and millimeter-wave circuits and systems. For the first time, in this research a dual-post band-pass filter is designed and simulated in a three-layer substrate integrated gap groove waveguide (SIGGW) for 5G millimeter-wave frequency band applications. The filter includes 12 posts (6 × 2). Also, the structure facilitates to use resonant posts and so we can design the posts to add a transmission zero in lower rejection band. The design theory algorithm and its limitations are investigated based on the circuit model of filter. The results shows that FBW of 5% and a lower band transmission zero for the proposed 12 posts filter. Also, the results are verified by simulation using CST. According to the results, the proposed filter is a good option for Ka-band applications and can be used as the building block for suppressing the LO leakage that is commonly used for up-converting the 5G signal to Ka band.
