Abstract
Narrowband bandpass filters (BPFs) are in great need in future terahertz (THz) technologies to suppress EM signals beyond the operating band. THz filters and antennas play a crucial role in controlling and transmitting THz signals for the application of high data rate (6G) communication, non-destructive sensing, imaging, switching, and filtering. The proposed filtenna is designed using a dual-band THz BPF with a complementary split ring resonator (CSRR) metamaterial (MM). This paper suggests the circle in the pentagon (CP) filtenna and the simulation results show the filtering characteristics of two pass bands with resonant frequency (fr) between 6.3 and 7 THz and between 8 and 9.8 THz with a squared ratio of 0.54. Also, the maximum 3-dB bandwidth (BW) of 1.3 THz, low return loss (RL) of −28.46 dB, and low insertion loss (IL) of almost 0 were attained. The proposed antenna radiates at the frequency of 6.8 THz with an RL of −27.72 dB. The proposed CP filtenna applies to various wireless communication, especially in drone-to-drone communication with excellent data rates.
