What is the name of the set?
<p>For a wireless system, a problem needs to be considered in the <a href="https://ctrfantennasinc.com/how-to-make-a-433mhz-antenna-design/">433MHz antenna design</a>. The 433MHz antenna design is a very precise task. A good 433MHz antenna needs to consider issues such as frequency band, impedance, and gain.</p> <p>The simplest 433MHz antenna design is a <a href="https://ctrfantennasinc.com/433mhz-whip-antenna/">whip antenna design</a>, which is a <a href="https://ctrfantennasinc.com/what-is-a-1-4-wave-antenna/">1/4-wavelength</a> line placed on a ground plane. The most common examples are used in wireless broadcast radios, cable equalization amplifiers, amateur radio stations, and cellular phones.</p> <p>All <a href="https://ctrfantennasinc.com/antennas/">antennas</a>, like any other element, have at least two connection points. For whip antennas, there must be a connection point and ground connection, although there is only one circuit trace and one battery in the ground layer area.</p> <p>The whip antenna and the ground layer combine to form a complete circuit. A magnetic field is established between the <a href="https://lcantennas.com/product-category/omnidirectional-antennas/whip-antennas/">whip antenna</a> and the ground wire layer. When current passes through the field, the entire circuit is formed. The ideal ground plane should extend at least 1/4 wavelength around the whip antenna base, or more.</p>
