The paper proposes an octagon shaped Microstrip Patch Antenna suitable for
dual band applications. The striking features of this compact, planar antenna are
sufficient isolation between the two operating bands and an area reduction of -
29% in comparison to a conventional circular patch antenna operating in the
same band

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

Abstract:
Experimental investigations on Microstrip line excited Dielectric Resonator Antenna configurations suitable for Mobile Communication applications are reported. High permittivity (εrd = 48) resonator samples with different aspect ratios are employed for the study. Theoretical analysis performed using FDTD method is also presented.

Abstract:
A slot line fed planar dipole antenna with a parasitic
strip for wide band applications is presented. The presented antenna
offers a 2:1 VSWR bandwidth from 1.66 to 2.71 GHz covering the DCS/
PCS/UMTS and IEEE 802.11b/g bands with a gain better than 6.5 dBi.
The uniplanar design, simple feeding, and high gain make it a versatile
antenna for wireless applications
