It is worth noting that the proposed modular antenna resembles reader antennas for NF-FF applications [19]- [22],
where two antennas are combined to contemporarily cover the near-field region and the far-field region. Such solutions
consist of a square patch with a segmented loop antenna [19]-[20], a distributed capacitor loaded segmented loop with a
backed metallic plate [21] and a folded-dipole loop antenna [22]. .
