Problems solved by technology

In this frequency band, if the variation of the VSWR of the antenna is large, the similarity relationship cannot be ensured between the spectrum of the signal input to the antenna and the spectrum of the signal output from the antenna.
As a result, the waveform of the output signal is destroyed from the waveform of the input signal

Embodiment 1

[0109] Below, based on the attached Figure 1-18 and Fig. 26 illustrate a first embodiment of the present invention.

[0110] figure 1 and figure 2 A perspective view and a cross-sectional view of the single conical antenna 10 of this embodiment are respectively shown. The single conical antenna 10 has a power supply electrode 11 , a ground electrode 12 , a dielectric member 13 , and a power supply terminal 14 .

[0111] The power supply electrode 11 is an electrode made of a conductor, and its shape is a tapered surface (conical surface) of a cone. The power supply electrode 11 can be formed by, for example, plating the inner side surface of the dielectric member 13 .

[0112] The ground electrode 12 is an electrode made of a conductor, has a disc shape, and has a concentric cylindrical through-hole 12 a at the center thereof. The ground electrode 12 is perpendicular to the center line of the conical surface formed by the power supply electrode 11, and the center line ...

Abstract

A mono-conical antenna as a dielectric antenna includes: a feed electrode having a conical surface; a grounding electrode having a flat surface positioned at the vertex side of the conical surface with respect to the conical surface; and a dielectric member arranged between the conical surface and the flat surface. The outer circumference of the dielectric member has a shape spreading from the conical surface side toward the flat surface side. Thus, the size of the dielectric antenna can be reduced and the dielectric antenna can have a wide range of a frequency band suppressing the maximum value of the VSWR to a small value.

Description

technical field [0001] The present invention relates to an antenna mounted on a dielectric body, in particular to an antenna mounted on a dielectric body suitable for miniaturization and wide frequency band. Background technique [0002] In recent years, the popularity of portable information processing devices having wireless communication functions has been remarkable. As wireless communication of such an information processing device, communication such as a wireless LAN using electromagnetic waves of a frequency in the 2.4 GHz band (2.471 to 2.497 GHz), for example, is often used. [0003] On the other hand, UWB (Ultra Wide Band: Ultra Wide Band) communication using a frequency band much wider than conventional wireless LANs is also proposed. UWB communication is also called pulse communication (impulse radio frequency, impulse radio:), by receiving and sending pulses with a very short width, data is received and sent. In this way, since pulses with a very short width ...
