A novel compact and wideband shorted patch antenna

Abstract

A novel compact shorted patch antenna with the bowtie‐type patch and the dual triangle portion to obtain a large bandwidth (790–970 MHz) is presented in this paper. Using shorted patches with via holes, a size reduction of 95.7% is achieved, as compared to that of the conventional half‐wave patch antenna. Moreover, it has 10‐dB return‐loss bandwidth of 20.4% for the GSM and CDMA bands. This proposed antenna exhibits not only a compact and a thin profile, but also wideband characteristics. © 2005 Wiley Periodicals, Inc.

Design of compact microstrip antennas using a modified ground plane

“…It can be seen from the figures that even though the resonant frequencies are reduced the bands are still maintained. The proposed antennas are compact and have a wider bandwidth compared with antennas reported in the literature [1–14]. The efficiencies of the antennas designed were measured using the Wheeler Cap method.…”

A Quasi-Omnidirectional Antenna for Modern Wireless Communication Gadgets

“…Modified coplanar waveguide can act as an efficient radiator embedded with attractive features like planar structure and easy integration with active devices without via holes [5]- [7]. Conventional bandwidth enhancement techniques like slot loading and integration of parasitic patch provide good results at the cost of distorted radiation patterns [8], [9].…”
