phase shifter for phased array antenna

i want to know how can i design a phase shifter myself which is cheap and efficent.i need it for electronic beam steering.

phase shifter and cheap
well i made my own project in of phase shift antenna in just 1 dollar by using the LC in parallel combination phase shifter but u have to do mathematical calculation for frequency u r using.

Can you send me the details of the design.Or just tell me a website from where i can get help.It would be a hige favour.

phase shifer design depends on frequncy which u r going to operate. It can be switched line, loaded line,etc. For phase shifter design u can refer www.microwaves101.com and Inder bahl Book for lumped element design.

Refer to John D.Kraus J.Marhefta. Antennas for all Application. third edition full mathmatical explanation is given and whole project was made easy by this book.
Also THE ARRL Antenna Handbook: best book for antenna and application.

is there any ic available for this purpose?

hybrids are usually used for phased shifting
