When an antenna is installed on a ground, the final antenna characteristic shows a combined effect of both elements. 例如,一个dipole天线单端70mm长度谐振频率是0.93GHz,而一个70mm的monopole天线安装在一个长度为120mm的ground上面的时候,天线产生了0.78GHz和1.28GHz两个谐振。 the fact we need to remember...
Application of artificial ground planes in design of compact cavity-resonance dual-band high-gain antennas is presented. The artificial ground plane consists of periodic strip grating on grounded dielectric slab. A code based on method of moment (MoM) is developed to analyze and design such ...
A compact patch antenna with a flared groundplane that may be integrated within a wearable hyperthermia system for the treatment of the intact breast disease is proposed.A 3D simulation-based approach was employed to optimise the antenna design with the objective of maximising the hyperthermia ...
Numerical optimization has been ubiquitous in antenna design for over a decade or so. It is indispensable in handling of multiple geometry/material parameters, performance goals, and constraints. It is also challenging as it incurs significant CPU expens
归类:如图1所示为一倒F天线(IFA, Inverted-F antenna)。这种天线似乎是线天线,但在对这种天线的辐射方式进行分析之后,就会发现它应该归类为孔径天线。 馈电:馈电在接地(Ground Plane)与IFA的上臂(Arm)之间。 上臂:IFA的上臂的长度大约是波长的四分之一。
The characteristics of antenna structure on three different types of ground planes have been studied. The results show that the ground plane plays an important role to achieve matching between expected resonances from the unit cell analysis with the antennas resonance. 展开 ...
This calculator can be used to design a Quarter Wave Ground Plane antenna, with radials. The radiating element is a quarter wave (λ/4) and the radials are 12% longer. There are usually four radials, three being a minimum, but you could use up to six. This is a true unbalanced ant...
Therefore, designers need to ensure proper sizing of the ground planes. If properly done, batteries and cables linked to the device have less impact on the antenna.Design the transmission lineIn PCB antennas, the transmission line is an RF trace which transmits RF energy. Designers need to ...
