The only responsibilty I can claim for the designs that follow is for finding them on the web! Many clever antenna designers have worked on designs for 1296MHz. For me, one of the interesting things about this band is the variety of weird and wonderful designs which can work on this band, compared to the ubiquitous yagi for VHF bands and the dish on the higher microwave bands. This is probably the most simple and inexpensive antenna you could make for 23cm. It has about 9 dbi gain, a 60 degree beam width with a clean pattern, and f/b ratio > 25 db. The picture to the left shows the antenna oriented for horizontal polarization. Here's how to make one: Cut a #12 copper wire (with vinyl insulation) to 44cm. Development of a 23cm patch antenna Looking for a robust design for a portable antenna to use with my new DJ-G7E, I decided to try a microstrip patch .
