    摘要： A mobile radio communication apparatus with an improved antenna for promoting easy manual operations, insuring desirable acoustic characteristics, and preventing the antenna gain from being lowered by user's head or hand during communication. An antenna is mounted on the upper surface of a casing and made up of a rectangular first conductive plate parallel to and spaced apart from the upper surface by a predetermined distance and having a length L.sub.1, a rectangular second conductive plate extending perpendicularly from the first conductive plate and having a height H.sub.2, and a rectangular third conductive plate extending perpendicularly from the second conductive plate and in parallel to the first conductive plate. A short-circuiting plate extending perpendicularly from one side of the first conductive plate by a height H.sub.1 and has a length M as measured in a direction parallel to the length L.sub.1. The short-circuiting plate has the end thereof connected and affixed to the upper end of a particular surface of the casing where the earpiece, mouthpiece and operation secton are arranged. The height H.sub.1 of the short-circuiting plate is greater than said height H.sub.2 of the second conductive plate, while the length M of the short-circuiting plate is equal to or smaller than the length L.sub.1 of the first conductive plate.

    摘要： Unidirectivity is achieved in an antenna including a microstrip portion and a unipole portion. The microstrip portion includes a ground plane conductor, a radiation plane conductor dielectrically spaced from the ground plane conductor, and a conductive member connecting the radiation plane conductor to the ground plane conductor., The unipole portion of the antenna comprises a unipole coupled to the radiation plane conductor. The radiation fields of the microstrip and unipole portions intensify each other in a single direction to achieve unidirectivity.
