    A Low-Profile Reflector-Enhanced Drop-Shaped Printed Antenna for Wide-Band Wireless Communications by Giovanni Cappelletti, Diego Caratelli, Renato Cicchetti, Claudio Gennarelli, Massimiliano Simeoni, Orlandino Testa

    Published 2017-01-01
    “…The geometry of reflector, feeding line, and dipole arms is optimized in order to achieve a broad operating bandwidth useful to meet the requirements of modern wireless communication protocols. Furthermore, the particular shape of the metal reflector and the adoption of a thin low-permittivity dielectric substrate result in a low distortion of the radiated field and a limited back radiation which makes the antenna suitable for UWB applications as well. …”
