High frequency transmitter-receiver

   
   

A high frequency transmitter-receiver which can prevent an antenna pattern from being broken. A radar apparatus is provided with a high frequency antenna, a base plate and a module. The antenna is comprised of an organic substrate and a metal pattern formed on the organic substrate. The high frequency antenna is adhered to the base plate astride the module. Here, the gap between the base plate and the module where the antenna is adhered is configured to satisfy the expression (an amount of change in gap size with respect to a change in use temperature).div.(an original gap size).ltoreq.6%.

Un transmisor-receptor de alta frecuencia que puede evitar que un patrón de la antena esté roto. Un aparato de radar se proporciona una antena de alta frecuencia, un embase y un módulo. La antena se abarca de un substrato orgánico y de un patrón del metal formados en el substrato orgánico. La antena de alta frecuencia se adhiere al embase a horcajadas en el módulo. Aquí, el boquete entre el embase y el módulo donde se adhiere la antena se configura para satisfacer la expresión (una cantidad de cambio de tamaño de boquete con respecto a un cambio en el boquete original el size).ltoreq.6% del uso temperature).div.(an.
