A novel compact coplanar strip fed dipole antenna with a step cut suitable for ultrawideband (UWB) application is developed. The antenna is evolved from an open ended slot line by symmetrically etching out two rectangular metallic parts from its upper inner corners. The antenna has 210 dB reflection coefficient from 3.1 to more than 12 GHz that covers the Federal Communication Commission (FCC) specified UWB frequency range. From the simulation and experimental studies, it is found that the proposed antenna delivers moderate gain and stable radiation patterns over the operating band. Time domain analysis on the proposed antenna has been conducted and was found that the antenna can be used for UWB applications. The proposed antenna occupies a compact size of 28.5 3 10 3 1.6 mm 3 .

“…Quasi-Yagi antennas can be fed by several different types of feedlines, including microstrip lines [1]～ [3], [12]～ [19], coplanar waveguides (CPW) [4]～ [7], coplanar striplines (CPS) [8], [9], and slotlines [10], [11]. Microstrip line-fed quasiYagi antennas with regular-dipole-driven [1]～ [3], [12] ～ [16] or folded-dipole-driven [17]～ [19] feeds are usually chosen for array implementation, since the feed configurations of CPW-, CPS-, and slotline-fed antennas make them unsuitable for array applications.…”

This paper presents a closely spaced two-element folded-dipole-driven quasi-Yagi array with low mutual coupling between adjacent elements. The antenna utilizes a T-junction power divider as the feeding network, with an input impedance of 50 Ω. A microstrip-stub is added to the ground plane in the middle of the two elements to improve the mutual coupling characteristics. The folded dipole driver is connected to a 50 Ω microstrip line via a broadband microstrip-to-coplanar stripline transition with a quarter radial stub. A mutual coupling of less than -22 dB is measured between two folded-dipole-driven quasi-Yagi antennas with a center-to-center spacing of 30 mm (0.55 λ0 at 5.5 GHz). The proposed quasi-Yagi array yields a measured bandwidth of 4.75～6.43 GHz for the -10 dB reflection coefficient and a gain of 6.14～7.12 dBi within the bandwidth range.

“…Printed dipole antennas using horseshoeshaped [2] and spider-shaped [3] forms to implement WLAN 2.4/5.2/5.8 GHz applications were reported as well. Besides, several dipole antennas with a composite structure to create two distinct resonant modes for achieving dual-band operation have been presented in [4,5,6]. These antenna designs, however, can not be easily integrated with an access point due to their large sizes.…”

Abstract:A planar folded dipole antenna suitable for WLAN and WiMAX applications is presented. By properly using a pair of multibranch strips in the radiator, the proposed antenna with a small size of only 35(L) × 4(W) mm 2 is capable of achieving dual-band operation about 2.35-2.51 GHz and 4.82-6.22 GHz. Moreover, the resonant frequencies of the antenna can be flexibly adjusted with various strip lengths. Experimental results show that the proposed design behaves not only good omnidirectional coverage but also stable gain variation across the operating bands. With a compact size, the proposed folded dipole antenna is thus satisfactory for integration with an access point as a transmitting antenna for WLAN/WiMAX operations.
