“…For the 'strip line dipole antenna' discussed in [4] as well as for our 'microstrip pseudo-monopole antenna' the radiation patterns for frequencies above 6GHz start to deviate from the half-wave dipole patterns shown in figure 8. The reason for this deviation will be discussed later on.…”

In table 3 we compare the azimuth gain characteristics of the shortened pseudo-monopole antenna with those of the strip line dipole antenna, [4] Freq.

“…Both dipole arms consist of two metal layers on opposite sides of the PCB substrate, electrically connected through metallised vias located on the rims of the circular arms. This latter antenna will be used as benchmark (even though the circle diameter is 19.5mm, [4], where the diameter of 'our' circle is 19mm).…”

“…In [2], a solution to this possible problem is shown including a strip transmission line feed and a tapered balun. In [4], a 'hidden' strip line feed is used. The strip line is positioned halfway between the two layers of the bottom dipole-arm.…”

Low-cost, compact, circular planar dipole UWB antennas have been designed, based on the 'two-penny dipole'. One of the dipole arms has been integrated with the ground plane of a microstrip transmission line, the strip being connected to the other dipole arm. The use of microstrip in stead of stripline technology hardly degrades the radiation characteristics, but simplifies the antenna architecture considerably. Up to 6GHz the azimuthal gain variation does not exceed 3dB. For frequencies in excess of 6GHz the antenna becomes too long, resulting in the forming of elevational lobes and large azimuthal gain variations. Shortening the antenna, results in gain-uniformity in azimuth for high frequencies at the cost of a resonance shift beyond 3GHz. As shown by the first full-wave simulations, this shortening may be realised without compromising the in-band return loss specifications. First measurements performed with antennas realised on FR4 -although hindered by cable-current effects -indicate the correctness of this approach. By inserting a slot in the upper arm of the dipole or inserting a spurline filter in the microstrip part of the antenna, a stop band from 5GHz to 6GHz may be realised.

Abstract-In this paper, a wideband planar dipole antenna is proposed. Compared to conventional dipole antennas, this antenna has wideband impedance matching, simple structure and compact size. From EM simulations, dimensions of antennas are chosen for better performance. For verification, this newly proposed structure is fabricated and measured. It is shown that return loss of the antenna between 2.5 GHz and 8.0 GHz is better than −10 dB.

In this paper, we use the ultra wideband antenna array combined with particle swarm optimization (PSO) to minimize the BER for indoor communication systems. Three types of antenna arrays, namely the circular shape, L shape, and Y shape arrays, are used in the transmitter and their corresponding BER on several paths in the indoor environment are calculated. On the basis of the topography of the antenna array and the BER formula, the array pattern synthesis problem can be reformulated into an optimization problem and solved by the PSO. The novelties of our approach is not only choosing BER as the object function instead of the sidelobe level of the antenna pattern, but also considering the antenna feed length effect of each array element. The particle swarm optimization algorithm is employed to optimize the excitation voltages and feed lengths for these antenna arrays to reduce the BER. The strong point of the PSO is that it can find the solution even if the performance index cannot be formulated by simple equations. By the obtained antenna patterns, we can know the route with the lowest BER; meanwhile, transmission power using this route can be reduced. Numerical results show that the synthesized antenna array pattern is effective in focusing maximum gain to the line-of-sight path for these antenna arrays. The synthesized array pattern also can mitigate severe multipath fading in complex propagation environments. As a result, the BER can be reduced substantially in indoor ultra wideband communication systems. The investigated results can help communication engineers improve their planning and design of indoor wireless communication.
