Abstract:
|
An electrically small, broadband-modified, truncated
ground metamaterial EZ antenna is presented. This, a modified EZ
antenna system, achieves a larger bandwidth of the order of 650 MHz
by adjusting the metamaterial-inspired meandered ground element fed
by a top loaded monopole. The design is devoid of the large ground
planes and the external parasitic elements used in conventional
designs for achieving proper impedance matching characteristics. The
antenna requires a small foot print of kg/5 3 kg/10, where kg is the
guided wavelength corresponding to the lowest frequency of operation,
when printed on a substrate of dielectric constant 4.4 and thickness
1.6 mm. The antenna offers a 2:1 VSWR bandwidth from 750
MHz to 1.4 GHz, which covers CDMA, GSM, and ISM bands |
