A CPW-fed Inductively Coupled Modified Bow-Tie Slot Antenna

Abstract

A CPW-fed inductively coupled bow-tie slot antenna is introduced. Several geometric parameters of the antenna were varied to observe the impedance matching between the CPW-feed and the antenna. The inductively coupled CPW feeding mechanism makes the concept suitable for array applications. The bandwidth reduction for an inductively coupled straight-dipole slot is overcome by utilizing an inductively coupled bow-tie slot. Antenna models for operation at 2.45 and 5.5 GHz were constructed and return loss and radiation pattern results were obtained. The proposed antenna provides bandwidths of 8 and 13% at 2.45 and 5.5 GHz, respectively.

A frequency reconfigurable bow‐tie slot antenna with wide bandwidth

“…A bow-tie slot antenna is a good example of a wide slot antenna, and it has wider bandwidth than the conventional slot antenna [5][6][7]. However, there are two things to consider when we achieve frequency reconfigurability by using a bow-tie antenna.…”

A Planar Inductively Coupled Bow-Tie Slot Antenna for WLAN Application

“…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.…”

Broadband coplanar waveguide‐fed slot antenna for wireless local area networks and microwave imaging applications

“…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].…”
