This study presents a new design of a triple band-notched ultra-wideband antenna. The designed structure of the antenna is based on two radiating strips, and a microstrip feed-line on the front, an inverted T-shaped element and a partial ground on the back. By etching a slot off the ground plane, another resonance is excited resulting in the extended bandwidth. The antenna with new structure occupies a small size of 20 × 14 mm 2 . The measured results show that the antenna has a wide bandwidth from 2.8 to 12.5 GHz for voltage standing wave ratio less than 2 apart from the rejected bands from 3.0 to 3.8 GHz, 5.1 to 6.1 GHz and 7.8 to 8.9 GHz. Meanwhile, radiation patterns and gain at various frequencies have been given.

“…Diplexing circuits play a significant role in transceiver front-end wireless systems. They can effectively separate Tx/Rx channels connected to common wideband or dual-band antennas [10][11][12][13]. Therefore, a diplexer technique can be employed to accommodate a system with multiple frequency bands and multiple functionalities.…”

In dual-band RF front-end systems, to transmit different frequency signals in different paths, each path requires the power to be divided along two transmission channels. In such systems, a circuit is created in which the input ports of power dividers with different frequency bands are connected to the output ports of a diplexing circuit in a cascade form. These circuits often contain different band filters in their schemes and have a complicated design. In this paper, an innovative technique for designing a diplexing power divider for Ku-band applications is presented. The proposed structure is designed on multilayer printed circuit boards (PCBs) and the utilization of a transition based on an extended SMA connector. The extended SMA connector provides two separate paths for the transmission of the RF signals. Hence, the proposed structure eliminates the need for intricate and bulky bandpass filters, allowing seamless integration with other planar devices and components within Ku-band satellite subsystems. In fact, the proposed architecture channelizes the divided output electromagnetic signals into two separate frequency spectrums. With the presented technique, two frequency ranges are envisaged, covering Ku-band applications at 13–15.8 GHz and 16.6–18.2 GHz. With the proposed structure, an insertion loss as low as 1.5 dB was achieved. A prototype of the proposed power-divider diplexing device was fabricated and measured. It exhibits a good performance in terms of return loss, isolation, and insertion losses.
