“…In this paper, a novel stacked patch antenna with compact structure is proposed to meet dual‐band and diverse patterns requirements. The frequency ratio of the proposed antenna is 2, which is larger than the antennas in References . The center frequency of lower band f 1 is 2.45 GHz, which mainly depends on the coupling between the upper circular patch and lower turnstile‐shaped patch.…”

“…In order to solve the problem of narrow band, stacked annular patch is introduced to design a slot antenna with dual band performance and omnidirectional radiation in Reference , the experimental fractional bandwidth is 19.3% and 18.6%, however the profile height of the designed antenna is up to 21 mm. In Reference , a novel circular patch antenna with circularly periodic mushroom units is proposed. The measured results show that the proposed antenna has the feature of two resonant modes—zeroth‐order resonant mode and TM 02 mode.…”

A dual‐band patch antenna with diverse radiation patterns is presented in this paper. Circular patch and turnstile‐shaped patch are placed up and down to obtain dual band characteristic. Two surface current loops on the circular patch and turnstile‐shaped patch work like equivalent magnetic dipole. Four rectangle slots and four PIN diodes are loaded on the circular patch to readjust the surface current. Due to the changed current path, an equivalent electric dipole is introduced and two dipoles with phase difference of 180° are combined with each other to achieve directional radiation pattern. By switching the states of the diode to control the connection states of the rectangle slot on the circular patch, then a dual‐band antenna with diverse patterns is designed. The measured results show that the overlapping bandwidths of lower band f1 is 2.9% (2.42‐2.49 GHz) and over 2.9 dBi gain, the overlapping bandwidths of upper band f2 is 2.0% (4.87‐4.97 GHz) and over 4.8 dBi gain. The measured patterns of f1 show that the proposed antenna can not only omnidirectional radiation but also directional radiation with a scan angle of 90°. Meanwhile, the measured patterns of f2 remain omnidirectional radiation.

“…In some applications there is a need for operating at two separate sub-bands, which is an alternative to the enhancement of total bandwidth. These applications have given a boost for research on new techniques that overcome the bandwidth limitations of the patch antennas [1,2,3,4,5,6,7,8,9]. Dual-frequency antennas have a single radiating structure and have two distinct resonant frequencies [9].…”

Abstract.A union shape has been proposed for getting the dual band operation of the micro-strip patch antenna operating at the 2.19 GHz and 3.98 GHz. In this work the patch shape is modified by uniting semicircular shapes at the two radiating edges of the square patch. A simulation study of the proposed antenna structure with probe feed has been done with finite element based commercial software HFSS. It is showing the dual band operation with return loss less than -25 dB at both the bands. The antenna offers a gain of 3-7 dB and nearly 2% bandwidth.

“…To satisfy the demand of European Digital Dividend (791 ∼ 862 MHz), CDMA800 (825 ∼ 880 MHz), and GSM900 (889 ∼ 960 MHz) simultaneously, the dual-polarized antenna should cover the bandwidth of 790 ∼ 960 MHz. Although many kinds of base station antennas have been proposed in [2][3][4][5][6][7][8][9][10][11][12][13][14], there are still some improvements should be made. Some of these antennas [2,7,8] have a narrow impedance bandwidth that cannot cover the bandwidth from 790 MHz to 960 MHz.…”

Abstract-A compact dual-polarized antenna element integrated with balun is proposed. Two pairs of dipoles are employed for the dual-polarizations of the antenna, and strong mutual coupling between them is introduced to widen the bandwidth of the antenna. Bent dipoles are used to reduce the size of the antenna. The simulated and measured results show that the proposed antenna can cover the bandwidth ranging from 790 MHz to 960 MHz with VSWR < 1.5 and isolation > 26 dB. The antenna element is also fabricated and tested. The measured results show that the antenna can be a good candidate for the design of European Digital Dividend/CDMA800/GSM900 mobile communication base station antenna.
