A container including an RFID module is provided that includes a base, and an antenna pattern. The antenna pattern includes a first antenna film and a second antenna film on a first main surface of the base. The RFID module includes an RFIC element, a filter circuit, and first and second electrodes. The filter circuit is configured to transmit a current due to an electromagnetic wave at a natural resonance frequency to the RFIC element. The first and second electrodes are connected to the filter circuit. The first electrode of the RFID module and the first antenna film are electrically connected to each other. The second electrode of the RFID module and the second antenna film are electrically connected to each other. Moreover, a sheet resistance of each of the first antenna film and the second antenna film is 0.5 Ω/□ or more.

Many embodiments provide a frequency comb receiver that includes a PIN diode, a THz pulse generator block that generates THz tones (LO) for coherent frequency comb detection, an on-chip antenna for broadband detection and a driver stage switched by a series of buffers, where a repetition rate of the LO tones are tunable over a range and determines a spacing between two adjacent tones in the corresponding frequency comb.
