wiki/ news/ 2003-05-23 - Dave T designs v1 CPA's on RT Duroid PCB

Using Excel and EAGLE, Dave T created a GPS (1.575 GHz) and WiFi (2.422 GHz) antenna on a single piece of RT Duroid. Attached are the design files and his writeup.

These two antenas were a great success, except for the RT Duroid material that we used. It was soft and the copper radiator on the top tended to crack causing extremely large SWR values.

Tests of the actual antenna.:

  1. First tests, on the PSU HP 8357E VNA: 2003-06-04
  2. Second tests, at Xerox's Anechoic chamber: 2003-06-10
