Micro-strip patch antenna for transceiver
First Claim
1. A micro-strip patch antenna for a radiotelephone transceiver, comprising:
- a dielectric ceramic module for transmission and reception, comprising a first ground plate, a dielectric ceramic part disposed on the first ground plate, and a conductive patch disposed on the dielectric ceramic part and having power supply terminals; and
a circuit board, comprising a base, a second ground plate disposed on the base and connected to the first ground plate, and strip lines formed on the base, adjacent to but spaced from the first ground plate, and connected to the power supply terminals.

Abstract
A micro-strip patch antenna for a radiotelephone transceiver includes a dielectric ceramic module for transmission and reception having a first ground plate, just one dielectric ceramic part for synchronizing frequencies, a conductive patch on the dielectric ceramic part for transmitting and receiving electromagnetic waves, transmission and reception power supply terminals projecting from different sides of the conductive patch. The antenna also has printed circuit board having a base, a second ground plate on the base to contact the first, and strip lines formed on the base so as to be adjacent but spaced from to the ground plates. The strip lines take care of impedance matching, and antenna provides for the use of a single channel power supply without modification.
