“…As a result, most UWB slot antennas just have both low crosspolarization level and dipole-like (i.e., doughnut-shape) pattern within a bandwidth with ratio of no more than 3:1. The rectangular slot antenna's crosspolarization performance can be improved by inserting parasitic strips in the slot radiator [18] or by introducing a folded slot structure [19]. However, these methods are only effective within a relatively narrow impedance bandwidth with ratio of not more than 2:1.…”

Three novel, super-wideband antipodal slot antennas with different tuning stubs are studied and compared with each other. Smooth, half-circular slot profile is used to improve the antennas' polarization purity and impedance bandwidth, and different tuning stubs are used to finely tune the antennas' radiation performance. As will be reported, low crosspolarization level, stable dipole-like pattern, and flat gain performances can be obtained within an operation bandwidth of 6.3:1 by introducing a smooth antipodal slot structure and a cup-shape tuning patch.

“…Coplanar waveguide (CPW) fed slot antennas are becoming increasingly popular because of their ease of integration with microwave-integrated circuits (MICs) and monolithic microwave-integrated circuits (MMICs) [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. Specifically, CPW-fed antennas eliminate the need for via holes, reduce radiation losses and allow the easy placement of surface mount active and passive devices [15].…”

A broadband CPW‐fed semicircular slot antenna is proposed for 2–6 GHz WLAN (wireless local area networks) and microwave imaging applications. The total dimension of the bidirectional slot antenna is 80 mm by 50 mm and is designed on a 0.5‐mm‐thick Duroid 5880 substrate (dielectric constant = 2.2). The antenna operates from 2 to 6 GHz within VSWR of 2.5:1. The same antenna on a combination rectangular cylindrical cavity with cavity depth of 10 mm provides a directional beam, 11 dB front‐to‐back (F/B) ratio and a bandwidth of 63% (2.8–5.4 GHz). © 2007 Wiley Periodicals, Inc.

“…Lately there has been a growing interest on antennas fed by coplanar waveguides (CPWs) [1][2][3][4][5][6][7][8][9][10][11]. This is primarily due to the simplicity, ease, and cost advantage of using such lines for integrated circuits and antennas.…”

A CPW-fed inductively coupled bow-tie slot antenna is introduced. The bandwidth reduction for an inductively coupled straight-dipole slot is overcome by utilizing a bow-tie slot. Antennas operating at 2.45 and 5.5 GHz are proposed that have 10 dB return loss bandwidths of 12% and 17%, respectively. Prototype antenna elements and a two-element series-fed array were fabricated and tested to validate performance.
