“…UWB antennas with varied band-notch parameters are designed and built to eliminate UWB narrowband interference. Antennas for UWB are categorized into three types based on notch characteristics: fixed band notch frequencies, reconfigurable band notch frequencies, and continuously tuneable notch bands [1]. Spatial filters such as frequency selective surfaces (FSSs) above the antenna are used to reject unwanted bands and improve communication quality.…”

An ultra-wide band (UWB) antenna with C-band and X-band notches for wireless communication is presented. The designed structure is printed on a material of "Rogers 4350B" with ε r = 3.66, tan δ = 0.0037, and a thickness of 0.508 mm. This structure is designed to operate at a UWB range starting from 3.3 GHz up to 10.15 GHz with a stopband range from 6.75 GHz to 8.5 GHz. The rejected bands are the upper C-band (6.75 GHz-8 GHz) and the uplink X-band of the satellite (space to earth) from 7.25 GHz to 7.75 GHz. The overall antenna size is optimized, and its dimensions are 21 × 30 × 0.508 mm 3 . The antenna gain varies from 2.1 to 4.2 dBi at the passband, and its total radiation efficiency is 96.4%. The suggested structure is designed and simulated using CSTMWS software. Moreover, a prototype of the proposed structure is fabricated and measured. The fabrication process was done using photolithography techniques, and the measurements were done using an R&S vector network analyzer. Good agreement is achieved between the simulated and measured results.
