| Abstract: | A new dual port microstrip antenna geometry for dual frequency operation is presented. The structure consists of the intersection of two circles of the same radius with their centres displaced by a small fraction of the wavelength . This antenna provides wide impedance bandwidth and excellent isolation between its ports. The gain of the antenna is comparable to that of a standard circular microstrip antenna operating at the same resonant frequency. A theoretical analysis for calculating the resonant frequencies of the two ports is also presented |

| Abstract: | A microstrip antenna with large bandwidth is developed using a parasitic technique. Compared to the available wide-band antenaas, the proposed antenna structure Is very compact and gives a less distorted radiation pattern with frequency . An impedance bandwidth, eight times that of a conventional patch antenna of the same size, Is achieved. The concept of coupled microstrip line model is extended for theoretical interpretation of the impedance Loci |

| Abstract: | An arrow-shaped microstrip antenna with a pair of narrow slots embedded near the non-radiating edges gives wide impedance bandwidth. The experimental and simulated (!E3D) results show that antenna bandwidth is -3.5 times that of a conventional patch with the added advantage of reduced antenna size. The radiation characteristics are found to he uniform throughout the operating band |
