hello,
I am interested in doing my masters project in the field of radars and I have opted to design antenna for millimeter wave radar. Can any one guide me which antennas are most suitable for millimeter wave radars and their scope as well so that I can extend my project work in phd

thanks
 

Antenna types are selected according to radar type and application.

Some radars use low power and have a wide field of view; then patch or horn antenna is suitable.,

Other radars use high pulsed power and need a narrow beam width, and often must scan the scene. The classical approach is a parabolic dish with a mechanical scanner. Modern radars use phased arrays and electronic scanning.

There are MANY radar applications and versions. You should learn your topic with one particular application in mind. Then compare available antennas and select the best.
 

Thankyou so much for reply. Actually I am confused in selecting the antenna because I want a project that can have a future extension as well so that I can continue my work in phd. I am thinking to go for dual frequency, dual polarization stacked antenna. Can you suggest, will it be ok
 

For a "dual frequency" you should define the bandwidth. Dual polarization needs two independent orthogonal feeds and a symmetrical aperture. Conical horns can meet those criteria and serve as primary or secondary feeds in a higher-gain parabolic dish.
 

PLs read this paper "Planar High-Gain Dielectric-Loaded Antipodal Linearly Tapered Slot Antenna for E-and W-Band Gigabyte Point-to-Point Wireless Services " by Nasser Ghassemi, Student Member, IEEE, Ke Wu, Fellow, IEEE
Ke Wu is working on SIW structures for W band such as mono pulse antennas which are important radar
this topic is novel and too valuable

If you like it and if it meets your specification, why not? As this antenna was designed for radio links, check your output power and side lobes. Radars usually need such parameters met.
BTW I have no access to IEEE papers.
 

@ferdows
Upload the paper plz..
