Design and Development of an Annular Slot Antenna (ASA annular slot antenna keeping constant the operation frequency. II. DESIGN CONCEPT The annular slot antenna consists of a circular slot on a square, metal ground plane that is fed by a microstrip line, fabricated on the bottom of the Duroid substrate as can be seen in Figs 1a and 1b. Big Diode Fig. 1a ASA front side Ls1 L1 D1 D3D2 L2 Ls2 MICROSTRIP SQUARE RING ANTENNA FOR DUAL- BAND … In recent studies, concentric annular rings have been used for designing dual band antenna, where a second ring was placed within thefirstring,each operatingintheTM12 mode[10,11]and[12]. In[12], the impedance properties of a dual frequency concentric annular ring microstrip patch antenna are described. This patch operates at two

A rectangular slot antenna with improved bandwidth ... A rectangular microstrip slot antenna fed by a microstrip line, which achieves a very large bandwidth on a relatively thin substrate, is presented. The performance is achieved by employing a combination of a rectangular slot in the ground plane, and the use of the microstrip line perpendicular to the rectangular slot.

A Low-Frequency Annular-Slot Antenna James R. W ait The radiation characteristics of an annular slot cut in an ideally conducting ground plane are discussed. The voltage impressed between the concentric edges is assumed to be constant around the slot. The annular slot is backed by a hemispherical cavity which has
