The antenna body 1 includes: a base portion 11, a transition portion 12, and a tip portion 13. Wherein one end of the base part 11 is connected with the contact part 2; one end of the transition part 12 is connected with the other end of the base part 11; the tip end portion 13 has one end connected to the other end of the transition portion 12. The widths of the base portion 11, the transition portion 12, and the tip portion 13 decrease in this order.
The control signal enters the antenna body 1 from the contact portion 2. Inside the antenna body 1, the signal passes through the base portion 11, the transition portion 12 and finally reaches the tip portion 13, so that the signal can be transmitted and received at both the base portion 11 and the transition portion 12 and finally reaches the tip portion 13.
The contact 2 is a signal input terminal. Since the contact portion 2 protrudes from the antenna body 1. Therefore, when the signal connection point of the antenna and the circuit board of the bulb lamp is more convenient, the contact part 2 is only needed to be considered to be in contact with the circuit board, the wiring and the layout of the circuit board do not need to be comprehensively considered, and the antenna and the circuit board need to be connected in a surface contact mode of the existing antenna. The connection is convenient enough.
In addition, the antenna in the application adopts a layout with one wide end and one narrow end. Therefore, the antenna can be matched with the space characteristics in the bulb lamp, so that the antenna can be extended to the top end of the bulb as far as possible, and the antenna can be as long as possible. Therefore, the antenna is made as narrow as possible while the signal transmission area of the antenna is kept constant. Therefore, the condition that the antenna is too wide to block light and shadow occurs is avoided.
In an embodiment of the present application, the contact portion 2 is connected to the antenna body 1 through a first connection portion 3, and the first connection portion 2 is arc-shaped.
Due to the arrangement of the arc-shaped connecting part, the signal transmission direction of the signal in the process of transmitting the signal is smoothly changed, and the situation of losing the signal is avoided.
In an embodiment of the present application, a width of the base portion is gradually reduced in a direction away from the contact portion.
The bulb lamp is matched with the characteristics of the internal space of the bulb lamp, namely the bulb lamp is narrower towards the top. The width of the antenna is required to be narrower and narrower. Therefore, the widths of the base portion 11, the transition portion 12, and the distal end portion 13 may be gradually narrowed without changing their own widths. In the present embodiment, the width of the base portion 11 is also narrowed, so that the internal space characteristics of the bulb lamp can be better matched, and the edge of the antenna is smoother.
In an embodiment of the present application, the width of the transition portion is gradually reduced in a direction away from the contact portion.

The antenna described in this application may be a cone-shaped antenna when the antenna is narrowed, or may be an "S" antenna composed of a plurality of adjacent antenna segments as shown in fig. 2. It is within the scope of the claimed invention for the antenna segments 14 to be progressively narrower, or for the antenna segments 14 to each be narrower than the previous one.
The shape of the letter S is not necessarily strictly identical to the shape of the letter S, and may be substantially identical. It is within the scope of the present disclosure that adjacent antenna segments 14 are not necessarily parallel (or not parallel), that each antenna segment is not necessarily straight (or curved, such as curved or irregular), or that the connection portion between two adjacent antenna segments 14 is not necessarily curved (or has an angled bend angle, or an acute angle, or a right angle and an obtuse angle).
In an embodiment of the present application, two adjacent antenna segments 14 are connected by a second connection portion 4, and at least one of the second connection portions is arc-shaped.

In the present embodiment, the distance D2 between at least one set of two adjacent connecting portions is 0.74 mm.
As can be seen from fig. 3, the antenna efficiency of the antenna in the 2.4GHz band can reach more than 75%, and this efficiency value is ideal in the PCB type antenna.
Fig. 4 shows the directivity parameters of the antenna, and the directivity parameters and the antenna gain can be mutually derived.
As can be seen from FIG. 5, the antenna resonates in the 2412-2483MHz band, and can meet the requirement of 2.4GHz WiFi band application.
FR-4 is a code of a flame-resistant material grade, which means a material specification that a resin material must be self-extinguished after burning, and it is not a material name but a material grade, so that there are very many kinds of FR-4 grade materials used for general circuit boards, but most are composite materials made of so-called tetra-functional (terra-functional) epoxy resin plus Filler (Filler) and glass fiber.
Compared with the prior art, the method has the following beneficial effects:
