Hi Higler, OK, I understand the feeding issue - see attched for example. By the way the vivaldi antenna beamwidth is not smoothing and there are a lot of ripple. Is the Slot antenna that you present has such of ripple ? I need a smoothing beamwidth at 120 degree for Elevation & Azimuth...

Hi Higler, OK, I understand the feeding issue - see attched fo example. By the way the vivaldi antenna beamwidth is not smoothing and there are a lot of ripple. Is the Slot antenna has such of ripple ? I need that the beamwidth will be 120 degree for Elevation & Azimuth. RXTX

Hi Higler, See attached, Please review and let me that i drew it correct. I am still do not understand how to connect the center conductor from the PCB, Please explain. What about to use dipole antenna with the arms like a arrow - will it achieve beamwidth 120 degree ? What about patch...

Hi Higler, For a mass production issue: do you have idea how i can not solder the coax manually to antenna ?

By the way - the antenna need to be with Linear polarization.

Hi Higler, About the antenna with beamwidth of 120 degree, it is look that the slot antenna feed complicated. Do you have article for slot antenna with BW:7% and beamwidth of 120 degree ? RXTX

Hi Higler, I have a question from different subject: Why the Antenna Handset designer not design the Antenna to Dipole which has the ability to be indifferent to human (As a GND) ? RXTX

Hi Hilger, In the article from piers.org the is no data that they reach to beamwidth of 120 degree. The book i need to purchase. There is a lot material how to increase the BW but less material how to increase the beamwidth. Can you send me a meterial for antenna with beamwidth of 120 degree...

Hi Higgler, IF you increase the Er to 8 the BW is decrease. I need BW of up to 7%. Did you see patch antenna with this high BW and high Beamwidth ? Doron

Hi Higgler, Can i receive beamwidth of 120 deg ? (i know that the beamwidth of patch antenna is around 90 deg maximum)

Hi, I summerize the parameters: Antenna with a -3dB beamwidth of around 120 Deg. frequency of operation 4.5GHz Frequency BW :350MHz The antenna can be above PCB or on PCB. Please advice.

The frequency BW need to 8%

The antenna need to be above PCB on PCB.

Hi, I need to design Antenna with a -3dB beamwidth of around 120 deg,Is anyone has ideas which antenna is compatible ? The antenna need to be with High Gain as possible. Please advice. Doron
