pifa, IFA for multiband and it can be tuned to meet bandwidth you wanted.
i'm search for a pifa design for dual band operation, gsm/GPS..(gsm band of 880 to 960 MHz , GPS L1 frequency of 1575 MHz) can u help me please with the reference?
Any USB gsm/3G/4G modem or cell phone, if it have a FCC certification number can you find photos of the antennas at . Dominating type of antenna is multiband pifa for both modem and cell phones regarding this type of wide band internet connection.
Hi, i need antenna design pifa of quadband gsm 900/1800/1900/UMTS 890-960/1720-2170 MHz please anyone maybe have paper or book for reference
Hi, Kindly help me. I m designing a Balance pifa antenna in HFSS for gsm and UMTS (1900,2100). Q1 How to feed a Balance pifa antenna ? Q2 No current flows from my Patch,But gives a good Bandwidth and gain. Why no current flows ? Q3 How to match the pifa antenna impedance without changing the position of (...)

hi what is the advantage of single pifa antenna used in mobile for gsm and ism purpose over the multiple integrated pifa antenna ?
i want 2 design dua l band antenna on gsm 900Mhz & DCS 1800 Mhz band but with with very high gain of 7,5 dbi... so wich is gud1 pifa or ny other design.... plz rply i m runing out if tme... i want 2 strt simulatin it...
For a pifa on FR4 the easiest way would be to go to AWR site and download a 30 days trial version of MWO (or you can buy it, but is a lot of money). The EM simulator is user friendly, predictable, and very accurate.
Hello, I have designed a pifa gsm antenna on a FR4 PCB, but i want to run some simulation. Can anyone suggest me some software tool? Thanks in advance
Hi, I have simulated a single band pifa for gsm 900 applications. The center frequency is well coinciding with 925 MHz but the bandwidth is to small. |S11| is around -20 dB. How can I widen the bandwidth? I'm using Agilent ADS2005A momentum. Your guidance is appreciated in this regard...
Hi, I am designing a triple-band antenna for both gsm900/1800 and Bluetooth, and I want to know which antenna is suitable for such antenna whose Gain is also required to be 2dBi plus. Now I choose one Folded pifa, which works for gsm/DCS/Bluetooth Triple-Band Application. The paper is here,
I am looking for a good and simple pifa design that can be constructed from FR4 if possible printed on the board and mounted above a large ground plane. I have a large ground plane available, for 868 MHz it looks like several wavelengts. The antenna should able to cover: 868 MHz, 900 MHz gsm and 1700 - 1800 MHz bands. Thanks in advance. PS: I
To choose what antenna type is depend on what's your application and frequenies for example , The GPS combined to mobile phone may use ceramic antenna , these type can use monopole , heliex , slot , even patch ...etc for gsm communication , it can use IFA , patch , heliex ....etc the pifa is one of the most popular type for applicati
hi buddies, Attachment is one pifa antenna for two band 900/1800(or 850/1900),the performance spc is as below: EGDE/gsm TRP:29 , TIS :-104 DCS/PCS TRP:27, TIS:-104 SAR meet two standard; If we use the current antenna volume as attchment,Can meet the performance spc?Pls give you comme
Hi every one, can any one upload for me some designs of a dual band pifa for gsm and dcs. thanks in advance. best regards.
thanks.. is there any way to tune the pifa?? any equations? coz i got some designs from some papers.. but i need to modify abit to suit my application..
It depends on your project type, for a handheld equipment helix monopole would do , for car kit a whip type monopole would be good. For gsm handset antenna, pifa(Planar Inverted F Antenna) antenna is common. The whip antenna is the best, because it's bigger.
For mobiles the most used type of antennas are Helix and pifa, and for BTS are p@tch array / flat panel antennas.
For Base Station the most common are P@tch Array and Vertical Dipoles Array. For mobile the most common are pifa and Helix.
