“…where H t = H + H i is the total field, H i is the incident field produced by the source (2). We search for the solution of the mixed boundary value problems (4) and (5) in the class of functions that satisfy the radiation condition at infinity, which is taken in the form of the limiting absorption condition as well as the finiteness of energy in any bounded volume. The second condition in our case is reduced to the fulfillment of the Meixner condition at the edges of the cone Q 2 and at the vertex of the cone Q 1 .…”

The electromagnetic problem by the finite bicone, which is formed with the perfectly conducting semi-infinite cone and the finite cone with truncated vertex, is studied. Bicone is excited axial-symmetrically by the ring magnetic source.The diffracted field is represented through the series of the transversal magnetic (TM) modes; the lower mode among them is called the transversal electromagnetic wave (TEM). On the basis of this representation and using the mode matching technique, we derive the series equations to determine the unknown complex modes magnitudes. In view of the electric field singularities at the conical edges, these equations are represented in the form of the limiting transition from the finite sums to the series. We derive the rule of this transition, as well as the procedure for reducing them to the infinite system of linear algebraic equations (ISLAE) of the first kind. We study asymptotic properties of the matrix elements and find that the main part of their static limit and their behavior for large indexes form the matrix operator of the convolution type; the corresponding inverted operator in the analytical form is obtained. Both these operators, which we call the regularization operators, are used for the transition from the ISLAE of the first kind to the ISLAE of the second kind. The ISLAE thus obtained allow for the solution of any geometrical parameters and frequency with the given accuracy. The asymptotic properties of their solutions are analyzed, and the numerical examinations of the far field patterns are provided.

“…antenna exhibits high ripples in both azimuth and elevation plane and also poor omnidirectivity. A design of stacked biconical antenna for the frequency band 3-20 GHz has been shown in [4]. In [5], a double discone antenna can be found operating in the frequency range 0.18-18 GHz.…”

A novel compact antenna for ultrawideband channel sounding is presented. The antenna is composed of a symmetrical biconical antenna modified by adding a cylinder and a ring to each cone. A feeding coaxial cable is employed during the simulations in order to evaluate and reduce its impact on the antenna performance. The optimized antenna demonstrates S11 below-10 dB and a stable omnidirectional radiation pattern robust against the cable effect over the frequency band 1.5-41 GHz despite its compactness (the maximum electrical dimension is of 0.29λmax, where λmax is the free space wavelength at the lowest frequency of operation). A prototype of the antenna is fabricated and tested. The simulated and measured S11 are in a good agreement. Measured radiation patterns confirm the pattern stability in terms of the direction of maximum radiation and 3 dB beamwidth.

“…The wideband dipole antenna has been developed in two forms: three‐dimensional (3D) and planar‐type (2D). While the 3D wideband dipole antennas such as biconical are usually bulky and difficult to fabricate, the planar ones have some advantages such as omnidirectional pattern, low cost, light weight, conformity, ease of fabrication, and integrability with the surface mounted devices in the circuit …”

A new planar compact wideband dipole antenna is presented. The proposed antenna radiation pattern is omnidirectional and very stable in the operation bandwidth with good gain flatness and low cross polarization. Three cases of the proposed antenna are simulated by linear scaling of the designed antenna which proves the design flexibility. Finally, one case of the designed antenna is fabricated and measured. This antenna which works between 1.265 GHz to 3.98 GHz has very compact dimensions 82.4 mm × 45.5 mm (0.35l1 × 0.169l1, l1 is the wavelength in the start of bandwidth), stable radiation patterns and low cross polarization. These good specifications prove the antenna design capability and ability for wideband communication system applications.
