Monopole antenna design using HFSS - Forum for Electronics
Apr 11, 2013 · Re: Monopole antenna design using HFSS _antenna gain with respect to ground plan Here I am attaching three different test results of a monopole antenna in different ground planes. Monopole antenna resonating at around 2 GHz. By increasing the ground plane diameter the gain of the antenna is increasing. As per my results says, gain of 2 GHz antenna
optimal design of this type of antenna can yield an ultra-wide band-width with satisfactory radiation properties over the entire bandwidth. Antenna design: The proposed monopole antenna is illustrated in Fig. 1. A circular disc monopole with a radius ofR¼10 mm and a 50O microstrip feed line are printed on the same side of the dielectric
IFA VS monopole antenna - Forum for Electronics
Apr 17, 2024 · Because any monopole doesn't exist without ground plane, it's more appropriate to analyze it as asymmetrical dipole,. Secondly IFA usually appears as electrical small antenna (length < lambda/4). Detuning sensitivity mainly depends on antenna bandwidth respectively shortening factor.
reflector design for a monopole antenna - Forum for Electronics
Jul 4, 2005 · If you have a reflector to chang the antenna radition pattern ,then the performance of the reflector is affected by two aspects,one is the length of the reflector itself,and the other is the distance between the reflector and the antenna.Refering to the Yagi antenna principle,the reflector length is 1/2 of the wavelengeh,and the antenna spacing is 1/4 of the wavelength,and …
does monopole antenna need a ground plane? - Forum for …
Dec 4, 2007 · Re: monopole antenna Yes and no. A quarter wave monopole needs some sort of ground plane. That ground plane might be a piece of metal on the circuit board, the shield on a coax cable, or the body of a person holding the unit. How well the ground plane works determines the radiation efficiency and radiation pattern.
[SOLVED] CST Studio Microstrip Monopole Antenna Simulation
Aug 24, 2008 · Mixing antenna ground into the feed (by making feed ground part of the antenna) will drive you crazy later when implementing the actual layout. It seems that the original antenna design includes a series element, most likely for matching. So if you don't have 50 Ohm for the antenna itself, that my be correct. Good luck! Volker
How to design a DIY 915MHz monopole antenna? - Forum for …
Apr 15, 2011 · a monopole antenna is like a whip, and for best performance, you need to set the antenna height to 1/4 wavelength, i have attached a picture of monopole antenna and the link to antenna length calculator below. **broken link removed** here is a RF module external antenna height calculator and design guide.:lol:
Balun for Vertical 1/4-wave - required - Forum for Electronics
Dec 28, 2012 · "The quarter-wave monopole antenna is a single-element antenna fed at one end, that behaves as a dipole antenna. It is formed by a conductor lambda/4 in length, fed in the lower end, which is near a conductive surface which works as a reflector (see effect of ground) and is an example of a Marconi antenna.
Help with λ/4 monopole antenna. | Forum for Electronics
Oct 27, 2010 · A monopole antenna on a PCB ground plane is about as basic an antenna as you can get You could use semi rigid coax like UT-141 bring it up through a hole in the centre of the PCB ground plane, solder the upper side of the ground plane to the solid outer conductor of the coax and use the centre conductor as the radiator.
monopole antenna matching - Forum for Electronics
Oct 6, 2006 · I tried to design monopole antenna for 900MHz using HFSS. My antenna dimensions are Radiator length 90mm Radiator radius 0.5mm Dielectric radius 1.2mm Simulation gives me antenna impedance of 79ohm with some inductive part. Do i need to match the antenna impedance to 50 Ohm. When i connect...
