Patent abstract
A dielectric antenna is provided which uses a compounded material and exhibits a small change in relative dielectric constant at room temperature against a load due to temperature changes. The dielectric antenna includes a dielectric block, a radiation electrode, a feeding electrode and a fixing electrode provided on the dielectric block. The dielectric block contains a crystalline thermoplastic resin, ceramic powder, and an acid-modified styrenic thermoplastic elastomer. The acid-modified styrenic thermoplastic elastomer content in the dielectric block is 3% to 20% by volume.
