“…FEKO is a software package for electromagnetic field calculation. Based on the method of moments [5], the antenna modeling and simulation can calculate the antenna input impedance, current distribution and far-field and other performance parameters. It is to model and calculate the dipole in different lengths so as to determine the input impedance of the antenna resistance inductor load capacity.…”

This paper mainly discussed the performance of loaded logic periodic antenna, and proposed an approach to calculate the loaded impedances and inductors based on our analytical results. With the use of FEKO, the accuracy of the results calculated by an analytical model is verified with simulations. Finally, the properties of the loaded logic periodic antenna are further reanalyzed. As a result, there are more extremely effectors upon gain than VSWR and directivity in some frequencies where antenna is loaded.

“…A further size reduction can be achieved using one of the many techniques proposed in the literature for reducing the size of an LPDA [12]. Such techniques include using different shapes for the LPDA dipoles [13][14][15][16], using fractal layouts for the dipoles to increase the total length of the current path [17,18], reducing the axial size of the LPDA by reducing the boom length [19], or using the dielectric-loading technique [20], which can be applied both to wire LPDAs [13,15] and printed LPDAs [14,[16][17][18][19][20].…”

A printed log-periodic dipole array (LPDA) for DVB-T2 Digital TV applications, covering the whole DVB-T2 UHF band from Channel 21 to Channel 69 (470 MHz–860 MHz), is presented. The presented antenna offers a compact size and a lower cost compared to both wire and similar printed LPDAs, with a normalized area of only 0.26 λ2 (where λ is the free-space wavelength at the central frequency) and a similar (or higher) average gain. It is composed of meandered radiating dipoles, and it is implemented on FR4, the cheapest dielectric substrate available on the market. Moreover, the antenna size has been reduced to an A4 sheet dimension (210 mm × 297 mm) to cut down the production cost. The antenna has been designed starting from Carrel’s theory and using a general-purpose 3D CAD, CST Studio Suite. The results show that the proposed antenna can be used for broadband applications (≈74% bandwidth) in the whole operating frequency band of Digital TV, with a satisfactory end-fire radiation pattern, a stable gain, and a radiation efficiency over the required frequency range (average values 6.56 dB and 97%, respectively).

“…It can be understood from this article that the tapered structure can effectively increase the bandwidth and improve the impedance matching of the antenna and the antenna can be cut in half to achieve miniaturization [17]. Not only that, there are many ways to achieve multiband antennas, including coupling feed technology [18][19][20][21], matching network technology [22,23], and distributed inductive loading technology [24,25].…”

This article proposes a novel multiband antenna with “C + O” structure, which uses two classic circular letters and combines them. The antenna is suitable for wireless applications such as second generation (2G), third generation (3G), fourth generation (4G), WLAN, and Bluetooth. The antenna is based on the structural characteristics of the classic monopole antenna. It is a vertical quarter-wavelength antenna. The radiator of the antenna is mainly composed of letters, and the radiator is symmetrical along the feeder line. The antenna radiator is composed of “C + O” structure. The antenna uses a coplanar waveguide feeding method. After actual testing, the antenna covers two frequency bands: 1.82–2.66 GHz and 3.46–3.72 GHz. The center frequency points are 2.06 GHz and 3.68 GHz. The antenna uses FR-4 dielectric material, the relative dielectric constant of the dielectric plate is 4.4, and the actual size of the antenna is 15 × 15 × 1.6 mm³. The test and simulation have good consistency, which verifies that the proposed antenna meets the requirements of various wireless applications.
