Card-type radio receiver having slot antenna integrated with housing thereof
A slot antenna is integrated with and forms part of the housing for a miniature radio receiver having dimensions comparable to the dimensions of a credit card. The antenna is formed by three plates arranged to have a generally U-shaped cross section. One plate is on one side of and is approximately the dimensions of the "credit card" receiver. A second plate is much more narrow and extends along one edge of the other side of the "credit card" receiver in a spaced parallel relationship with the first plate. The third plate extends vertically between the first two plates and along the one edge of the "credit card" receiver. Together, the three plates make up not only the antenna, but also three sides of the housing of the receiver.
