ABSTRACT:
An antenna and its electronic circuit combination is presented to comprise a ground conductor plane 30, a radiating conductor plane 40 disposed in parallel spaced relation to the ground plane 30 and shorted at its one end to the ground plane 30. A ground plane 30 is preferably formed on a printed board 10 which is disposed in parallel relation to the radiating plane 40 to define therebetween an open air space. Mounted on the printed board 10 and received within the open air space are electronic components which form a receiving or transmitting electronic circuit 60 associated with the antenna structure and electrically coupled by means of a feed element 20 to a feed point 44 on the radiating plane 40. Consequently, a number of electronic components forming the electronic circuit for the antenna can well be incorporated within the antenna structure by better utilization of the open air space formed between the radiating and ground planes, giving a space saving compact arrangement to the antenna and its electronic combination suitable for installation in a limited space.
